The device is Texas NE5532P which is NIPDAU/SN (Nickel Paladium Gold over Tin) so it won't be corrosion but some kind of tarnish or foreign gunge. It's on the top of the pins not the bit that gets

Re: QDX FLrig JS8Call Pi4
John, the way FLRIG is designed to work is that it connects to your radio, then all your other software looks at FLRIG as being your radio. In your example above, ?If JS8Call¡¯s radio is something

Thanks for getting back Greg. Also, thanks for the feedback on the attenuator. I am getting the heartbeat and maidenhead with the GPS so I guess all is well. Quite impressive for sure. -- 73, Rick

Hi Rick, Those settings seem right to me. If you display the heartbeat signal on the LCD and you see it pulsing, I think you can be sure you are disciplining the frequency. This is the #HB special

Peter, Been there-done that! - You popped one (or maybe two) of the BS170's - easy just to change all 4. Some folks have even installed sockets for the BS170's - Like "Smarties" always keep a supply

OK. Figured it out. Going through the menus I noticed that the Ref Freq was reset to 27 MHz with the new update chip. I installed a TCXO some time ago, so upon changing the freq to 25 MHz, SWRs went

QCX Firmware Update - High SWR
I think I'm missing something. This behavior is so bizarre: Purchased 1.09a chip from Hans and inserted into 40m mini. 5 watts out with 1.0:1 SWR into a dummy load. All good! Then tested on my dipole
