I managed to damage my "KKMoon" 25 MHz DDS signal generator while testing a chassis this weekend. Even through I was being careful, and using a decoupling cap, contact with the IF stage took out one channel's output. I'm annoyed with myself for this, but realistic about the low cost and subsequent fragility of the unit.

Anyway, should anyone else be in possession of one of these units, be warned that extra care is needed to prevent damage. I am actually thinking of making an R.F. isolating transformer for the output.

The unit is useful (and precise) enough, that I ordered another. I also scoured eBay, and picked out an old Heathkit signal generator. The Heathkit will probably want a bit of restoration, but I chose it because it allows for modulation (good for RF stage alignment) and is "Tough as old Boots" when dealing with vintage gear. And I like them Icon_smile

Cheers
