Worth Its Weight in Gold

I have an IC-705 and IC-9700 at home, but I spend most of my time at my girlfriend's house 10 miles away. SDR Control allows me to remote either rig, which means I get to spend more time on the air. The setup is a little finnicky, and requires some time to get right, but the app itself just works.

Now if I could just add remote capability to my IC-7300, I'd be thrilled! At least I can access my local repeaters from a remote location, which means a lot given my involvement with my club.

Works ok, but FT8 is very poor compared to WSJT-X

Works well on ssb and general RX. But, is lacking on FT8. Better off running remote desktop into pc in the shack and running WSJT-X there. Ive ran this app on iphone, ipad, and a new Macbook M3. Ive found that WSJT-X on pc connected via usb and my ios devices connected via LAN or WAN at the same time there is a huge difference. The app is always decoding the same data 6 to 12db lower than WSJT-X does. Once WSJT gets to -13 to -16 the app is already -21 or lower and missing decodes. Once WSJT-X gets below -16, this app no longer decodes. What was odd was on the Mac version i enabled alerts for a DX call i could see on WSJT-X and the app would alert the sound, but never display it. All filtering was off. Even tried it with filtering. So it appears a coding issue and threshold on when the decodes no longer display. I emailed Marcus and he basically said hes seen the same thing and it is what it is. Appears he has no desire to dig into it. So, if your looking to use it for FT8, dont. I bought a brand new Macbook Pro M3 3 days ago thinking the faster processor may help. But its not processing i can see. Its the levels in the coding of the app. Other than that, app works good. Usually when i have found bugs he has been great at emailing back and working on a fix. This time it appears as if he is saying it is what it is. Kinda disappointed. Guess i shouldnt have bought the mac or the app.

Developer Response ,

Unfortunately, this user confuses a couple of things and is wrong with most of what he wrote about FT8. I tried to help him to understand his mistakes but it looks as he never received my answers. There is also no need to use a 'brand new MacBook Pro M3' as decoding has nothing to do with CPU speed. The App just decodes well even on older Macs.

Best HAM software I own!! Worth every penny

I have to say that I purchased an Icom IC705 based on this app being available. I know that is not the normal approach but, I was not disappointed. I wanted rich remote features for use via an iPad, not just CAT control. SDR Control for Icom gave me almost everything.

I was up and running on it in an hour or less (New radio, new application). Unlike many apps, this is logical, well designed and simple. No flustration, it just works.
