This is the Norcal FCC-1 frequency counter with the addon FCC-2. The Case is a PacTec Electronic Enclosure. It's a multimeter case with back stand built into the rubber boot that surrounds the case. It ws a very tight fit and I used a dremel tool to get it into the case. I still have to mount the input and output connectors. The FCC-2 transmits CW and RTTY with RTTY software to generate the Mark and Space. Output is about 10 to 25 MW. I am working on a 5-10 watt amp. The two kits are $35 each. The FCC-2 is a SMT kit.
