Workbench/signal generator

Sorry but I don't understand your comment, I'm trying to learn by not ordering the wrong connectors?
I'm not going to build that particular item, I'm looking into building the rf sampler that you had described. I want to order the correct BNC connectors to put in the box along with the proper cables to connect the box to the scope or counter.

The female BNC's are correct. That isn't the point. You want to build a 1k generator to test radios with. That isn't necessary, when you can use your computer to do the same thing:

Freesound.org - "TONE 1 kHz 44.1 16bit.wav" by klangfabrik

That sample is used to feed the mic when aligning the TX coils.

If you are going to monitor the radio's output signal and freq, it is better to build a standard RF Sampler. It is much easier to build an RF Sampler and use far less parts to accomplish the same thing than the one you proposed to build. IIRC, that the one you've chosen has a AM Demodulator circuit, and that isn't really necessary for bench work. Your choice also uses a padded direct signal rather than a sampled signal, and I would steer clear of that or you may burn out your test equipment if you make a mistake. Just sayin is all . . .

They only real way to do it accurately for RX is to get a sig gen that has the 1000hz signal already built in. You need to use standard tools to get predictable and accurate results.

Thanks Rob, once again you saved me money and educated me.
I found you post on signal file.

And I will need:
1-metal box
1- 100 ohm reistor
1 -ferrite coil
2-so239's (rf in and out)
1- female BNC connector
1- male to male bnc cord
mis wiring

I use a HP 8656A signal gen and I'm happy with it.
And the RF Sampler is the cheapest way to go. You can buy them too but I think they get way too much for what they are.

I ordered the necessary parts that I don't have to make the sampler.
I like to homebrew projects, it helps me with the learning curve.
