Back in the days I had two channel or carrier generator that put out about 50 dbmv at 7Mhz and 40Mhz for example.
lent it out and last I've seen it. had a small signal generator that had 5 switches on it for frequencies like 10, 20, 30, 40 and 60Mhz. worked great, but it died and can't seem to find something small that can generate return carriers like 10, 30, 50 and 85Mhz that can be connected in the field and check levels at the node or headend.
could used an old 3.0 diag modem to generate the carriers, but it only goes to 65Mhz and with systems going from 42Mhz to 85Mhz I would like something small that I can put in my backpack and runs on batteries.
what do you use/recommend?
