RUMlogNG is a HAM radio logging, QSL handling and printing tool, especially made for the short wave DXer, made by a DXer. Basic logging features are included for the higher bands up to 1.2 cm and for satellite. RUMlogNG can handle an unlimited number of logs and an unlimited number of QSOs per log. Clublog data are used for automatic DXCC recognition.

Four user definable logging fields are available for your convenience.

Work in your favorite contests or run a dx-pedition using RUMlog, including full scoring and ESM mode.

Using RUMlogNG you can print QSL label and manage your incoming paper QSLs. The Logbook of The World (LoTW) and eQSL are fully supported, and you can create files for the Global QSL service very quick. You can get different statistics for paper- or LoTW QSLs. It's just a mouse click to upload or download new QSLs to/from eQSL or LoTW.

RUMlogNG can use the K7PT dx activity and QSL manager database to inform you about current dx activities and it can build and use an own manager and IOTA database, extracting the information from dx-cluster spots. Provisions are made to query the or online library.

RUMlogNG keeps you up to date about worked, confirmed or missing DXCCs and provides you with country lists and detailed statistics. Quick log searches or more detailed log queries and export routines are possible.

RUMlogNG can establish a dx-cluster connection via the internet or to your local skimmer. A simple terminal is integrated for a Packet Radio connection. RUMlogNG will separate DX-spots and alert you ,new one' DXCC or IOTA spotted.

RUMlogNG can interface with your transceiver, setting the main parameter on your TRX from the logbook or vice versa. Kenwood, Elecraft, Yaesu and Icom transceivers are supported. More controls are provided for the Elecraft K3, KX3, KX2 or IC-7300. It can control the K1EL Winkey chip. microHAM devices are supported, the MKII and DKII are fully configurable.

RUMlogNG has import and export functions to allow exchange of log data to other logging tools.

Except the DXCC statistics, RUMlogNG tracks the most interesting areas of the world for the most important awards: IOTA islands, CQ zones, ITU zones, Grid Squares, US States, US Counties, German DOKs and more.

RUMlogNG interacts with Clublog and keeps your online log synchronized in real time.

Good program, for general and contest logging

Tom has written a very versatile logging program. It has many features (ie grayline, QRZ integration, etc.)- too numerous to comment on. The key features - entering logged QSOs, importing/exporting ADIFs, LOTW integration - work flawlessly. Transceiver and Winkey connections work well.

The contest module is great fun to use. It has many contests pre-configured, and it includes all of the ‘modern’ features one would expect: ESM, Super Check partial and so on.

It is well worth downloading, spending a few hours getting to know it, and a donation if you use it on a regular basis.

Great, highly stable and versitle program

This is a great logging application. I enjoy using unix based software with amateur radio as I never have any issues with the stability of the system. Using online QSL is quick and easy. The real-time sync with clublog is great and I also enjoy the seperate, yet intergrated, contest logger. This is perfect for someone like me that contests casually, but this provides a competitive edge when needed. I've never had a problem with the CAT control, works great with both of my 590's. Absolutely worth downloading and donating.

Great Logger

Has everything a Mac user like me needs for SWL/MW DX'ing and logging, when almost everything out there is Windows-based. Being able to use a large scope on the iMac rather than the small one on the radio is wonderful for my aging eyes.
