Re: Bizzare issue with MMDVM Hat harmonics and 5GHz WiFi

I've managed to find a work-around for now, I can get it to stay on 2.4GHz by changing the ssid to bssid in wpa_supplicant.conf and then specifying the MAC Address of the 2.4GHz radio on my router. That will work fine here, but that is not an ideal work around for anyone using a 5GHz hotspot "p...

Re: Bizzare issue with MMDVM Hat harmonics and 5GHz WiFi

Hi KN2TOD, That's interesting that you have had a similar problem albeit from a different cause. Did you check the signal strength when you were connected to the 5GHz WiFi band?

Why are most designs using the wrong TCXO/OSC Pin?

Looking at several Simplex and Duplex MMDVM “HS Hat’s” I have here that I’m going to change the TCXO to a higher quality part. I noticed that ALL my boards (Of all different designs) have the TCXO output going to the OSC1 Pin on the ADF7021, but that pin is for using a 0.8V Clipped Sine TCXO output,...
