Re: Should we adopt the KD8CEC firmware?
Gentlemen and ladies too, As one member of a software/hardware development team (W0EB/W2CTX/N5IB), I've hesitated to join in this discussion for fear of being thought as "dissing or denigrating" Ian

I believe there are ¡°ElseIF¡±s for #define variables too so this is quite powerful. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner - Operator Big Signal Ranch ¨C

Re: Should we adopt the KD8CEC firmware?
I have seen this approach used on the Ten Tec REBEL and PATRIOT and in my opinion was a disaster for people who do not know what we are talking about! Taking this approach I suggest an application,

Re: Variable IF
Hi Tom (or anyone else that knows :), Curious where you sourced the diodes, an Ebay search only showed Asian sources, are there reliable ones there, or known good ones in the US? Thanks, very. Scott

Re: Oops - variable bandwidth IF
One could try 2n7000, source grounded and the drain connected to a 470pf which is in turn connected as a tuning cap of the filter. Changing gaye voltage will change the effective reactance of the

Re: Should we adopt the KD8CEC firmware?
I agree with K9ZC. ?The easiest way to free up code space in the Nano is to use conditional compilation for "optional" features that not everyone wants. This is the approach taken with the K3NG/ NANO

Re: Variable IF
I'll draw something up, take a picture and post it as soon as I get a chance. I have some other changes, simple ones, that also are worth the effort and I should post them also.

Re: Should we adopt the KD8CEC firmware?
I think it could be done without too much confusion by using preprocessor directives. That way, you don't actually mess with the code; you only change the symbolic constants you wish to affect. For

I have already built your BITX40 which I am using with great satisfaction. I have just received your "Micro BITX40". I ask you if I can feed the two IRF510s separately with a higher voltage to get a

This is where problems will begin to occur. Are you going to add in functionality to modify ubitx_menu.ino on the fly? Or are you going to break up ubitx_menu.ino into a lot of little pieces that can
