“The one with some bug fixes” Be sure to check the release notes for prior versions to see what's new! I update the app regularly in response to feedback like yours. Read them at https://greylineft8.com/changelog.html Remember that Greyline now has a comprehensive user manual at https://greylineft8.com/userguide.html - you’ll also find a button in the Settings view to take you there Shoutouts: ON4LDZ - Suggesting visual indicators to tell you why stations were skipped in automatic modes K7DFS - Confirming the very popular FT710 works perfectly with Greyline! Features: - You will now see visual indications on messages that were skipped in automatic modes. WAIT indicates the station was calling you but not responding, which carries a fixed 5 minute cooldown period. SKIPPED indicates a timeout in the Hunter mode, FILTERED indicates that you set a CQ filter which this station violated, and WORKED indicates the station would be a duplicate if you worked them. - When the app flips into an RR73 recovery mode while running Gatherer, the RR73 recovery will show up in the queue so you can decide whether to continue with it, reprioritize it, etc Fixes: - Occasionally, a picosecond-scale rounding issue would accumulate and cause message slots to be shown as 1s earlier than they should be (for example, :59 or :29 instead of :00 or :30). This was a cosmetic issue only and did not affect actual transmission slots, but it looked bad. So it’s fixed now! - Moving from an RR73 recovery to the next queued call in Gatherer mode would sometimes skip a TX slot, wasting 30 valuable seconds. Now it doesn’t - CQ filters were being improperly persisted when a station changed their addendum. Now the filters are applied to the most recent call rather than the first one heard in the session That’s it, that’s all, folks! Thanks for bringing me on your activations - now get out there and POTA on. 73!

“The one that lets you get really odd” Be sure to check the release notes for prior versions to see what's new! I update the app regularly in response to feedback like yours. Read them at https://greylineft8.com/changelog.html Shoutouts: CT7DBJ - Suggesting (among other folks) the ability to pick even vs odd time slots for CQ calls JK1TBL - Pointing out that not all FT4/FT8 takes place on the default frequencies K7DFS - Requesting a tip jar link (aww, thanks) Features: - You can now pick whether to call CQ on even (:00, :30) or odd (:15, :45, and the half-second FT4 variants) time slots. Note that this only applies to CQ calls you initiate, whether from the manual or automatic modes. When you respond to another user’s call, you will always still use the opposite parity you heard them on. - Bands now have a custom frequency option - tap the pencil icon next to the displayed frequency above the waterfall to edit it. While this won’t change anything on your radio, it *will* change what frequency you report to PSKReporter, the POTA cluster, and gets written into your logs. Customized bands will have an orange indicator to remind you they’ve been changed from their default, and there is a new setting in the Settings page which allows you to automatically return edited frequencies to their default on each app launch - Added a new Buy me a Coffee link in the Settings menu. Totally optional, but I’ve been humbled by hearing folks tell me the app is underpriced for the value it provides. If you genuinely feel like you’re getting more than 4 bucks worth of value from it, feel free to send me a note and know that I appreciate you! That’s it, that’s all, folks! Thanks for bringing me on your activations - now get out there and POTA on. 73!

“The one that makes logging even more awesome” Be sure to check the release notes for prior versions to see what's new! I update the app regularly in response to feedback like yours. Read them at https://greylineft8.com/changelog.html Shoutouts: ON4LDZ - Catching some odd behavior in how we assessed duplicate contacts N2YCH - Pointing out an inconsistency in when we consider a contact loggable K4RZO - Mentioning that editing filled text fields was annoying Features: - Introducing a comprehensive User Guide! https://greylineft8.com/userguide.html - you’ll also find a button in the Settings view to take you there - Validated the Yaesu FTdx10 as supported - Gatherer mode now logs upon sending RR73 rather than waiting for the 73, which is consistent with other FT8 applications available - We now flag duplicate log entries during a POTA activation. Logs that are duplicated during normal operation don’t get flagged, but to avoid accidentally submitting logs with dupes, you will see an orange DUP indicator on any duplicate entry in a POTA log - During a POTA activation, there is a new counter for “This Park” in the logging view. It will be red when you have 0-4 contacts, yellow for 5-9, and turn green once you hit the magic 10 mark. Only non duplicate entries count towards this counter, so you know once it’s green you’re good to go - Duplicates are now assessed not just based on callsign, but callsign, band, and mode. This is accounted for in the green rows in the band activity view, as well as both automatic modes. So if you’ve worked me KB0RB on 20m FT8 before, I won’t show up as green on 30m FT4 and the automatic modes will work me again - We now prompt you to resume a POTA activation already in progress if you quit the app and come back in. It happens, and you shouldn’t have to restart the activation if it does - New support for multiple POTA log exports - if you’re doing multiple activations in a day, your logs will be separated properly and you’ll have one touch access to each one at any point - Exporting a POTA log while an activation is still running now prompts you to end the activation in addition to exporting the log - Added an advanced algorithm to determine if we should retry and prioritize finishing out a QSO that got stuck in the RR73 phase. It stinks to get caught in the middle of an almost-done QSO and now Greyline will help, if it can - Tapping into any free text field with text in it auto-selects the text, to make it easier to replace Fixes: - iPhone control sheet now pops up as full height rather than half height. This is just a lot easier to use and feels less cramped - When the retransmission limit expired in Gatherer mode, we sometimes skipped a TX slot before returning to CQ. Now we go back to CQ as soon as possible, to keep that momentum up - The retransmission counter limit (number in parentheses after the “next TX” field) wasn’t being displayed in the collapsed view. Now it is - “Next TX” message was often updated too early, making it look as though you were sending a message that you weren’t yet sending. Now the behavior is much less confusing Whew. That’s a lot of stuff. That’s why this is a 1.2 and not just a patch release. Keep the feedback and suggestions coming! Thanks for bringing me along with you and 73!

“The one with the biggest update yet” I know I’ve shipped 14 updates to Greyline since I launched it back in June, but this is the single biggest set of additions yet. Buckle up, this is a big one! Be sure to check the release notes for prior versions to see what's new! I update the app regularly in response to feedback like yours. Read them at https://greylineft8.com/changelog.html Shoutouts: JK1TBL - Proposing a Cloudlog endpoint, providing an environment to test against, beta testing the app KR4EOD - Reporting a pretty major bug when working stations with a “/“ in their callsign ON4LDZ - Submitting a Field Notes entry VK2AWN - Writing a great blog! https://andrewwoodward.net/2026/08/08/260808greylineft8/ Features: - Greyline now supports Cloudlog and any Cloudlog-compatible logging endpoint! Just provide the API URL, API key, and Station Identifier and decide whether to auto-log your contacts to it! - The logging framework has been expanded to support QRZ, Cloudlog, and eventually WRL directly - stay tuned for that - Gatherer mode now provides a manually editable queue. This is, as far as I can tell, a first for FT8/FT4 software. When you’re working stations automatically, Greyline will queue them according to your preference (first heard, strongest signal, or furthest distance). But, with the new View Queue button, you can manually reprioritize them! Want to grab that station in Japan first? Been looking for that rare DX? Open up the queue and change the order that Gatherer will work them in. - Gatherer mode also now has a cooldown period - stations sending out of sequence or bad calls to you will be ignored for 5 minutes before we let them retry - POTA auto spotting now sends a “Thanks and 73” message to the cluster when you end your activation or export your POTA log Fixes: - We had a *major* issue with working stations that had a / in their callsign (think W1A1/3, for example) - the FT8 specification provided for how to handle this edge case, and I totally missed implementing it. Now, you can work these stations without a problem! If you ever saw callsigns that looked like “…” - you hit this bug. It’s fixed now. - The Custom Message feature now follows the message queue timer and allows for full-length inputs - Changed the label on the Stations Heard map from “All time” to “This Session”, which is more accurate - On the iPhone or in some cases portrait mode iPad, text that doesn’t fit in the allocated space in the band activity view will marquee gently, so you don’t miss important info - Added string validation to the manual QSO form - making sure that callsigns, grid squares, and signal reports only contain valid characters that can be parsed by logging software - Exporting a POTA log or cancelling an activation now inserts a visual line into your log, so you can see which entries were part of the activation more clearly - We now require a grid square to be set (either manually or via Location Services) in order to transmit - POTA auto-spotting can now be optionally disabled in Settings. Give it a try and please leave a review if you enjoy using Greyline! I hope it makes your activations just a tiny bit more joyful. Thanks for bringing me along and 73!

“The one where I make getting started easier” Be sure to check the release notes for prior versions to see what's new! I update the app regularly in response to feedback like yours. Read them at https://greylineft8.com/changelog.html Shoutouts: VK2AWN - Validating IC-7300 functionality, providing Field Notes and photo, suggesting CQ only filter KR3BST - Providing Field Notes and photo K4RZO the coyote - Providing Field Notes and photo Features: - Added a brand new first-time onboarding experience. This will help new users get set up and on the air quickly. If you're already set up but still want to check out the onboarding flow, there’s a button in Settings to start it manually. - Added a new filter to the Band Activity view that only shows CQ calls and exchanges that you’re actively participating in or that mention your callsign specifically. This can optionally be set to apply on startup - Links to the Field Notes site as well as support email are now in Settings Fixes: - Better handling of microphone and location permissions - Bundled latest version of Big CTY data Give it a try and please leave a review if you enjoy using Greyline! I hope it makes your activations just a tiny bit more joyful. Thanks for bringing me along and 73!

“The one where I improve signal decoding and add spotting” Be sure to check the release notes for prior versions to see what's new! I update the app regularly in response to feedback like yours. Read them at https://greylineft8.com/changelog.html Shoutouts: ON4LDZ - Reporting issues with live band activity view N9DNR - Reporting an issue with duplicate contacts being collected in Gatherer mode KR4EOD - Reporting discrepancies in signal report calculations Features: - Added live PSKReporter.info spotting. Spots are sent in 5 minute batches and include your callsign and grid location as well as the stations seen. Spotting is off by default, but can be activated in the Settings page - Added color coded signal reports in the Band Activity view - Added ability to filter the Logged Contacts view in the mapping page by time frame - Added a toggle to allow collection of duplicate callsigns when operating in Hunter or Gatherer modes (off by default) Fixes: - SNR computation is now more accurate and accounts for real world noise as opposed to bench standard noise levels. PLEASE NOTE: Comparing SNR computed in Greyline to that in iFTX or WSJT-X is not an apples-to-apples comparison. Differences in algorithms used as well as differences in AGC across device types plays a big role in these numbers. - When you navigate away from the Band Activity view, you are now automatically returned to the most recent signals upon your return - Gatherer mode no longer collects duplicate callsigns by default. You can re-enable this behavior in the Settings view if you like - Dropdown controls in the Mapping view sometimes re-drew slowly, but now they don’t Give it a try and please leave a review if you enjoy using Greyline! I hope it makes your activations just a tiny bit more joyful. Thanks for bringing me along and 73!

“The one where I add cool new mapping capabilities” Be sure to check the release notes for prior versions to see what's new! I update the app regularly in response to feedback like yours. Read them at https://greylineft8.com/changelog.html Shoutouts: ON4LDZ - Suggestions for map views and new data columns Features: - The Band Activity view now includes Distance and Bearing columns. Both are computed from your GPS coordinates to the grid square of the remote station. You can select the units for distance in the Settings screen - The Live Spots view has been renamed to Mapping, and now supports two additional visualization types - As always, Live Spots maps the stations which hear you based on live PSKReporter data - The Stations Heard view maps out the stations which you’ve heard in the Band Activity view - Contacts Logged will visualize the contacts in your log, by band - You can select the default view for your map in Settings Give it a try and please leave a review if you enjoy using Greyline! I hope it makes your activations just a tiny bit more joyful. Thanks for bringing me along and 73!

“The one where I add a ton of POTA support!” Be sure to check the release notes for prior versions to see what's new! I update the app regularly in response to feedback like yours. Read them at https://greylineft8.com/changelog.html Features: - Greyline FT8 now helps you run a POTA activation end to end. Park lookup, spotting, logging, and export are all handled in-app - Enable the POTA Activation mode in the CQ control panel and watch the magic. Greyline looks up parks near you (based on GPS or manual grid square,) adds the POTA addendum to your CQ calls, auto-spots you to the POTA cluster, marks your logged contacts as part of an activation, and enables a one-touch POTA.app compatible ADIF export. - POTA auto-spots happen when you start your activation, anytime you QSY to a new band, and periodically in between. Give it a try - I’m really proud of this release. I hope it makes your activations just a tiny bit more joyful. Thanks for bringing me along and 73!

Read them at https://greylineft8.com/changelog.html Shoutouts: K4RZO - My favorite coyote - for Identifying and helping me chase down some audio pipeline restore and timing bugs Features: - Big CTY data now automatically updates. We do a freshness check on each app launch, and force an update approximately once a week. Data loads are only about 300kb so bandwidth requirements are tiny. - Added a Time Debugging panel in the Settings menu. Most of you will never need this. But in case you see mis-timed messages, high instances of drift, or missed QSOs this screen will provide me the data I need to help track down the issue and make a better app for everyone. Fixes: - The audio pipeline now gracefully resumes when it’s interrupted - whether you accidentally activated Siri, unplugged/switched audio devices, or started the latest episode of your favorite Star Trek Podcast by mistake. Greyline now detects and compensates for these interruptions. - Minor change to a watchdog timer released in 1.0.9 to remove the risk of an extended TX cycle

Be sure to check the release notes for prior versions to see what's new! I update the app regularly in response to feedback like yours. Shoutouts: KN7AHS - Identifying a missing field in our ADI exports Features: - Greyline now makes use of Big CTY data courtesy of AD1C and ClubLog https://www.country-files.com/big-cty/ - This new data source makes grid square, call sign, State/Province/Country and DXCC lookup fast, reliable, and fully local with no internet access required - Greyline now supports both QRZ and HamQTH callsign lookups. If you’re an existing user, make sure to check out the Settings page and input your login for one or both! - Antenna tune mode now automatically applies suggested free frequencies Fixes: - ADIF exports now include the DXCC numeric code for every QSO - ADIF exports now include the Country identifier for every QSO, including non-US ones (whoops!) - Significant streamlining to log file handling and guard rails for bad or malformed data Thanks and 73 to everyone for the feedback and bringing me along on your activations!

1.0.7 Be sure to check the release notes for prior versions to see what's new! I update the app regularly in response to feedback like yours. Shoutouts: KJ5FVI - Requesting selective log export M0RVB, G7UFO - Suggesting “Tune” functionality Features: - You can now select only specific QSOs to export to ADI from your log. - Exporting to file will place a marker in your log showing when you last exported and how many log lines were saved - Now that we have this marker, there’s also now a simple “Export all since last” option that will save off all your logged entries since the last export to a new file - great for uploading to POTA.app or your external logger of choice - Added a new “Antenna tune” function - this function will transmit a constant carrier for a predefined amount of time. You can select the frequency from the main control panel, and the transmit duration from either the Settings menu or the Antenna Tune screen directly - The Tune screen will show a large-font countdown (or count-up, if you selected an unlimited time) so you can clearly see how long you have left if you walk away from your station to touch an antenna 25 feet away Thanks and 73 to everyone for the feedback and bringing me along on your activations!

Be sure to check the release notes for prior versions to see what's new! I update the app regularly in response to feedback like yours. Shoutouts: K0JGL - Reporting grid square lookup issues, confirming HF Pebble support IW2EYN - Suggesting log import functionality Fixes: - Grid squares were occasionally returning partially correct lookup results, due to an “alphabetically first wins” algorithm where multiple states, provinces or countries were in a single grid. Now we show everyone, no favoritism here! - When you highlight a log row, we now use much more readable and high-contrast colors Features: - Added the ability to import ADI formatted log files. Imported log entries will help you know who you’ve worked before. Note that imported log entries CAN be exported to a new ADI file, but can NOT be uploaded to QRZ. This is intentional, to prevent conflicts and duplication. Thanks and 73 to everyone for the feedback and bringing me along on your activations!

Shoutouts: K0ARG: Reporting issues with FT4 timing KL7EC: Support for TX-500 confirmed, now validating no spaces in callsigns NL7OT: Support for QRP Labs QMX confirmed IW2EYN: String validation in QRZ API keys, great club promotion! KO6IUH: Updated connection info for IC-705 Fixes: - When applying a manual override TX frequency, the frequency selection behavior changes to “Hold” and respects your selection. The app will always return to Auto Select mode on startup, since band conditions are always changing. - Applied dynamic delay algorithm to FT4 cycles to eliminate dropped symbols with high-latency audio devices. FT4 decoding is now SUPER reliable! - Always check previous band activity for grid squares. I never want to see a log entry without one again! - FT4 timing is now corrected and operates on the 7.5s cycle rather than FT8’s 15s one. - When FT4 mode is active, we now correctly display frequency settings at the top of the band activity view. - When tapping a message to restart a dropped or timed out QSO, R-signal reports are now correctly sent with the R prefix. - Ensured the 160m and 60m bands are not selectable for FT4 per the band plan. - If the message being sent changes in the middle of a TX cycle, update the band activity view with the new message. - When the retransmission counter is reached while in Gatherer mode, we now return to calling CQ instead of halting transmission. - When the retransmission counter is reached while in Hunter mode, we now call the next station on the next available TX slot instead of waiting several cycles first. - Sometimes, grid squares were not logged while in Gatherer mode. Now they should be. - String validation in the QRZ API key and Callsign fields, so phantom spaces should no longer cause problems. Features: - Added an option to preselect Previous, FT8 or FT4 as your startup mode. - Added a “Mode” selector to the logging dialog so you can pick FT8 or FT4 when creating a manual entry. - Added a decrementing counter in the status area, so you can see how many times a message is due to be retransmitted before we time out. Thanks and 73 to everyone for the feedback and bringing me along on your activations!

- Tapping the Live Spots view now forces an immediate refresh. Great for when you're just starting an activation!

- Changed how pending QRZ log uploads are displayed - Added a helpful button in Settings to redirect you to the Greyline FT8 website for tips on cabling and configuring popular radios
