Hi. Check out this topic: https://www.opengd77.com/viewtopic.php?f=11&t=2926&start=10 There is a short video showing the strange noise. Do you have a similar one? Kris, SP1KC Many people have this error and noise on 380/390/RT 3S. Noise or a complete lack of modulation, while the RSI shows receptio...

So the purpose of this backup is to be able to restore to the state when it was first flashed with OpenGD77? I'm not sure I understand the purpose, but I'm sure there are things I don't know about. Hence if you plan to restore your radio into a state where the memory contains the original data, the...

Thank you. Now everything is clear

Unfortunately, I can't figure out what has changed. SK2=Fn? Is it possible that the description is incorrect?

I have 2 radio stations: RT3S with GPS and 380UV without GPS. In RT3S I replaced the antenna, the amplifier, replaced the module with ATGM336H-5N-71. There are no special changes in the speed of satellite detection. It works very slowly. Finds up to about 9 satellites. In 380UV I put an external mod...

This is the active antenna ?, I presume it has power feed via the coax ? Does the radios with factory installed GPS also have an active antenna or do you need to add some power feed if you replace the original antenna ? There was no GPS installed in my radio station. I installed a kit with an activ...

I want to note that when installing a GPS kit, there is no need to make a cutout in the housing to accommodate a GPS antenna. The sensitivity is sufficient to place the antenna in a regular place. I also removed the antenna connector from the board and shortened the coaxial cable. The cable was sold...

You don't have to pick at the case - the board is placed to the right of the speaker. Unfortunately, the revision in the radio station without GPS did not fully work. The GPS board works when connected to a computer via UART, there is no connection with satellites at high speed.

When I use scanning my md-9600 can stop and I hear garbled Qso from the other time slot.

The same thing happens on RT3S. There is no such error on DM1801.
