Into my SDR. Build everything myself :) 2E0KZP Hello, could you tell me where are you from (grid square) and a little about yourself? According to the prefix, you should be from England, but the introduction is in broken English, subject is strange and Offcom open data (Spectrum tab in https://www....

Reporting Small bug: APRS transmission on RT-3S and DM-1701 writes APRS TX text over the channel name which is not erased. Either wrong line is written (and it should be one line bellow) or the text should be erased first. I do not observe the "GPS problem" on my radios, but I did not do settings re...

Hi, Possibly short press of SK1 on a channel / VFO with a APRS config, should send the APRS packet without needing to press and hold the PTT But this would be a departure from the existing functionality, where the PTT has to be pressed to transmit, except for DTMF contact dialing, where the radio tr...

Hi, whilst looking into e-shops, I found out these two PLUS models (boasting AES256 encryption) sold together under same listing as original ones. As no firmware is available on-line I would like to caution to check which model is being ordered as the eShops reference original FCC ID of MD-UV390, wh...

That's not a bug, it is a feature to go to sleep until before the next satellite pass. There should also be an alarm before that but I did not see it working.

Thanks for the tool information, unfortunately I am giving up on the V2 radio, as I have found out when trying to use it in real world conditions that it stops transmitting after 6 seconds when PTT is kept pushed even with all timeouts set to very high values or fully disabled (and VFO nor full rese...

Concerning the limits of MD-9600, just a two ideas which have been floating in my head: The MIC-E (or other) compression could be implemented to shorten the initial message. I was not able to find answer to this in APRS PROTOCOL REFERENCE PDF nor on web, so somebody with more in-depth knowledge can ...

I am not an expert per se, but I will just add my 2 cents. Would increasing the message length from 16 to 24 characters be beneficial. I am not sure if the length applies to user portion of the message or not? I think it would be beneficial to have the option (either by templating or by default) to ...

Probably not relevant, but on my Simplex MMDVM hotspot, I had to set the DM-1701 to TS2 to send/receive the calls via hotspot (TS1 did not work) - July 2023 versions, even when actually in simplex the TS setting should probably not matter.

The typo (wrong information) is in FAQ : The APRS position data is transmitted by holding the PTT, then pressing and releasing the SK2 button I managed to reach APRS gateway ~50km away after several tries without direct visibility and with 5W and it decoded correctly. Considering the DireWolf issue,...
