Frequency offset entry

Hi guys, I'd like to ask you for adding possibility to enter frequency offset to compensate frequency shift caused by non-working calibration. E.g. I have set-up 430.000000 MHz in radio but real frequency is 430.000270. Calibration doesn't have any effect and I have to correct/adjust frequency for e...

Calibration is not working

Hi guys, I've tried to setup and use GD-77 as radio and not just like a hotspot but I've found that TX frequency is 270 Hz above set/programmed/displayed frequency. The same situation and value as on DM-5R+ so tried to correct it by adjusting reference value in calibration menu - unfortunately no ef...

Re: Experimental Baofeng RD-5R version

I've bought one of this piece just for hotspot use but I'm curious why I'm not able to use this radio (with alternate firmware of course) against any RPT (Hytera RPT, MMDVM repeater based on Motorola radios as well as ADF7021 based hotspots/repeaters). I've spent a much time by try&fail attempts to ...

Re: New CPS with OpenGD77 Com port selector

Still the same situation is not communicating with Open software, maybe I have a bad cable. Hello everyone VY73! Jirka OK2JIQ I've solved the issue by installing English Win7 to virtual machine and everything works fine. There is issue somewhere inside Czech Windows and I haven't been able to find-...

Re: Unable to read/program GD-77 using OpenGD77 firmware

So I can confirm that I'm able to read/write the radio. I've downloaded Win10development image for VirtualBox from Microsoft portal, installed last community CPS including driver and can read/write radio without any problem. But I'm still interesting in the root-cause for Czech Windows issue. But fo...

Re: Unable to read/program GD-77 using OpenGD77 firmware

Regexp looks OK - it's looking for COM and one or more digit(s).

Re: Unable to read/program GD-77 using OpenGD77 firmware

The issue has been reported just from Czech HAMs so I've thought that is caused by Localisation setting (decimal pointer - dot or coma) - mostly typical issue on some SW running in Czech localization environment.i So I've changed localisation from Czech to US, removed driver, rebooted windows, re-in...

The latest Hotspot version is not 100% stable it still has bugs

Also, Did you press the Black button during startup?
I've just tried to start MMDVMHost and hold down black button when powering on the radio and It seems to be working fine. Thanks.
