Thanks for your input,ill look into this.No.....
But, if I understand what you are asking or attempting to do, it might be possible...
I suppose you want to use this as a piece of Test Equipment for possibly Servicing Equipment ???
I suppose you may want to make a "Probe" using Coax and Connectors ??? One end to screw onto the Input Connector and the other end, the Probe... Using the Coax Center Conductor as the Probe and the Outer-Shield as the Ground ???
NO Technician here, just a Tinkerer... BUT, I do own a ParaDynamics PD-256 Frequency Counter... It's Instruction Sheet shows "a way" you might be able to use your Counter the way I "think" you want to use yours ??? Notice the Additional Components that ParaDynamics provides... They prevent "False Readings" from being displayed, I believe, by the Counter being "acted-upon" by the Equipment it is connected to...
Anyway... Have a look here

I suppose, you could find a "Used", or Inexpensive "Probe" to use as a Base to Build upon... Or something like this ???

Or get Creative and Homebrew something...
Perhaps others may have First-Hand Experience with this ???
I am thinking it will work, as I describe... Nothing Ventured, Nothing Gained ???
" Don't hold me responsible, IF you try this and it does not work-out for you.... "
I apologize, if I made incorrect assumptions... I own the PDC-256 and have it connected internally to the Circuitry of my Vintage Tram D201A, using the Additional 2 Optional Components....
Very well, I read his post incorrectly.I believe he already has a "Counter"... I assume he wanted / needed a "Probe" to go with the Counter, in order to use it as a Piece of Test Equipment...
I believe in order to use the Counter as he had hoped to, the Probe would have to have the 51 Ohm 1/4 Watt Resistor and a 15pf Ceramic Capacitor in Series to the Tip of the Probe, in order for the Counter to provide Accurate Readings, and not having the Equipment's Circuitry effect the Counter's Readings...
No Problem !!! It happens to the Best of Us, Including ME !!! LOL ...Very well, I read his post incorrectly.
All the best.

No worries.No Problem !!! It happens to the Best of Us, Including ME !!! LOL ...
What is the best or close to best of a test frequency counter for am and ssb?No worries.
The SanJian Studio
PLJ-8LED Is cheap and may help you get started kaos513.
Not a whole lot of info on the net for this module but it seems to do the trick so far..
I think Captian Kilowatt already tried to explain it, but I'll go into a little more detail while keeping it simple.What is the best or close to best of a test frequency counter for am and ssb?
thanks will look into for a counter that is made for testing.I think Captian Kilowatt already tried to explain it, but I'll go into a little more detail while keeping it simple.
You Will Get To A Point When the Frequency you are trying to Measure gets So Low You are Going to need more than 6 digits to have a HIgh Enough "Frequency-Resolution" In Order to Display the Full (&True) Frequency in that Sub-Mhz Range;
Say Like When Taking A "Khz/Hz" Measurement.
6 digits of resolution won't get you close enough, and so you can not use a 6 digit Counter for Tuning a Radio.
Fictional & inaccurate example:
Literally drawing it out for You imagine two different counters where in front of you,
You had to take two readings one would be say 027.215 Mhz & the other could be 0500.2155 Hz.
How is the second reading going to display on the 6 digit counter?
Something to think about
All The Best.
