Re: Teensy 3.5/3.6 upgrade for uBITX
The uBitx has a 12mhz BFO. We have trouble on the uBitx with either the 12mhz USB port oscillator or the third harmonic of the 16mhz processor oscillator wreaking havoc with the receiver.? Could be

No way should anyone hate anything.? It may be an eye opener to some what can be done with a modern micro-controller.? I am glad Jack gave honorable mention to the Protoneer.? Before I ordered it

Re: KD8CEC 1.072 download
Im not sure you understand this completely, so ill put this more clearly. When the main sketch has the same name from version to version and you upload it to the Arduino IDE, it over-writes the

I¡¯m using the 78L08 and mv109. I may revert back to the capacitor and fine tuning pot. The real problem I had was stability, which I have now. 72/73 de Chas ai4ot

Re: Bitx20A bandspread
In varactor tuning, your goal is to maximize the capacitance variance from one end to the other. Therefore, the real questions are two: what varactor is being used, and what is the voltage range it
