Re: Experimental versions to fix potential speaker hiss

There is a bug : Start scan Click left arrow --> scan its inverted to down frequency stop scan with any key click arrow UP---> the frequency decreases instead of increasing NB but it was not possible to use the up and down arrows for more than 2 seconds for start scan ,thus leave free orange key :?: ?

Re: Experimental version with DMR Talk Permit tone

Originally I tried gettings the radio to receive on the alternate timeslot to the one it was transmitting on, but I was getting some strange effects on the DMR audio when I did this, which is a shame as it would have allowed us to monitor whether the repeater was still transmitting. But even in tha...

Re: Experimental version with option to disable CC filtering

I think possibly we may be able to speed up the CC scan function, by briefly disabling the CC filtering and then checking the received CC over several frames and then calculate which is the most likely CC for the Rx signal to be using. I don't think we can simply use the first CC on the Rx signal i...

MMDVMCAL is not supported as there is no need for this to calibrate the radio. The RSSI value is taken directly from the AT1846 RF IC, however the chip is not super accurate So if I understand correctly, mmdvmhost doesn't use the rssi.dat file? Is the value I read in the Pi-star dashboard read dire...

RSSI .DAT works?

I wanted to know if OpenGD77 supports RSSI.dat and if there is a way to calibrate it. I tried to launch pistar-mmdvmcal but it doesn't support OpenGD77
