Rather than read the bandswitch, a very common ham radio solution is to
have the frequency counter read both the VFO and the crystal oscillator
frequency and do the math with the last IF offset as part of the equation.
At least one unit can also reads the BFO frequency.
Although the low end PIC o

Nice combo, have one of those myself. Do check the power-lines.
The time-base is very analog for the high-res stuff.

Oddly I am familiar with TDRs. The curious point would be why you even
asked??
Thats sort of out of the blue.
Given that we are drifting off Marullos thread and even further from
time-nuts perhaps we could work off line on your question. By the way thats
a heck of a scope.

Hi Paul,
do you know about TDRs? I have a CSA803A with SD24 dual TDR head,
which I did not used for at least five years, now I needed it and found,
that in high resolution --below10psec --it became very noisy, [both
channels] any idea? the box is cca 15 years old , power-supply?

Yes, 3.1 version is even better, up to 60MHz:

Alex thats quite a good answer to the problem with a wide selection of
solutions that account for the IFs and such,
Marullo looks like you have a solution. Even a choice of displays.

whole number of other points depending on what you are after.

Thats a mighty old radio.
That being said reading the frequency of the VFO may or may not work out
for you.
The actual frequency will be made up of a number of other frequencies that
are injected at different stages.
Drake as an example actually uses the VFO in a plus or add on some bands

An Arduino can by pretty small. Here is an Arduino compatible that can do
exactly what you ask for.

Hello,

I need it to know its frequency, either the VFO alone (sub 6MHz) or
possibly its real rx and tx frequency (up to 30MHz).
Using the VFO would be easier but then
