COBRA 148 GTL ADDING FREQ. COUNTER
COBRA 148 GTL ADDING FREQ. COUNTER
I have a dyi freq, counter and would like to connect it so that it reads tx and rec freq. How do I connect? ![Very Happy :D](./images/smilies/icon_biggrin.gif)

Re: COBRA 148 GTL ADDING FREQ. COUNTER
DYI ? Havnt heard of that one, Is it anything like the SS3900 type counter ?
Re: COBRA 148 GTL ADDING FREQ. COUNTER
The diy freq meter is a counter kit from electronics-diy.com measures freq fron 10 to 60 MHz.
it can measure weak signals from crystal oscillators. sorry about the DYI. AT 84 my fingers are a little tired
Thanks for the come back, keeps me on my toes.![Very Happy :D](./images/smilies/icon_biggrin.gif)

Ah right, I did actually think DYI was a model, I wasn't playing grammar police.
I cant help you on this one as i only know how to connect up a 3900 type counter [CRT superstar kf v1] for the 148, Theres plenty of instuctions around for this maybe it could give some clues, You never know.

Re: COBRA 148 GTL ADDING FREQ. COUNTER
surrely some one out there can answer this simple request---or is there?
Re: COBRA 148 GTL ADDING FREQ. COUNTER
lets try another approach-----can anyone tell me where to connect a freq meter to read both tx and rec on any cb unit,
probable not!

Re: COBRA 148 GTL ADDING FREQ. COUNTER
The only way to read the TX and RX freq on a radio is to hook into the offset oscillator, however, this will not give you the on channel frequency, as it would need to be mixed with another frequency (to match the radios IF), for instance if you hooked into the 148, you would be seeing a 34MHz frequency, if you then had a mixer circuit installed too then that could deduct the 7.8MHz IF from that to give the correct on channel frequency.
