Re: Public Beta (2021 09 05)

Great Job Roger, will you implement the possibility to download NOOA satellites in the future? You need to edit the satellites.txt file which is installed in the same folder as the exe of the CPS, and add extra satellites Set the tx freq to 0, to prevent accidental transmission All perfect Roger , ...

Re: HOTSPOT MODE RANGE

Also keep in mind that the GD-77 in VHF although it seems to have an excellent sensitivity actually has a bad filtering, and therefore as soon as you connect it to an external antenna the radio becomes deaf. I have carried out comparative tests between ID-51, D878 and GD-77 and you can see how the G...

I can also listen to a distant signal in DMR but I am in a local QSO, or there is a jammer ... in short, the choice it should be as personal as all radios have, if you t...

Re: Update 15th March

yes also in VFO, only in simplex, when I press the PTT only the display light comes on, but it does not go to TX, when they stop talking I can transmit, it is as if the Busy PTT Lock were active
