OpenGD77

Hi david, in our club are many GD77 devices from the bad RX audio at 100% charged battery. My modification has fixed the error. I am thrilled... Whether the own device is affected, one can recognize fast. Charge the battery to 100% and listen to a QSO.... But the soldering is not suitable for beginn...

Hello Colin, Thanks for the link. Fixed bad RX audio today. (Battery charge over >90%). RX audio now works UFB! There is a little more space for the SMD resistor than in the instructions, an SMD soldering pad is free directly behind it! 10k resistor replaced with 15k! http://tyrofly.at/forum/Audio_G...

Hello Colin and GD77 team,

with a fully charged battery (>90%) the RX-AUDIO is not so good....
Is it possible to fix the RX-audio problem with a hardware modification on the GD77? I would be willing to solder a little too.

Thank you !

hello roger,

I get this error message with the current CPS at the end of the installation or when I start the CPS.
When I install an older CPS, the error message is not present!
A colleague has the same, so not an isolated case.

Merci Roger !!

If anyone has this problem, I can recommend these (internal) microphones. They work perfectly! https://www.amazon.de/sourcingmap-Elektret-Kondensator-mikrofon-Pick-up/dp/B00OK6GPWC/ref=sr_1_1?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=2M61A3H3NCET5&keywords=sourcing+map+8+St%C3%BCck+2+Pins+L%C3...
