Hi - Well if you want to try the transmitter, there are a couple of places to get ham-band crystals. These guys
http://www.expandedspectrumsystems.com/prod4.html have a good collection but they are wire-lead types so you must adapt them to the crystal socket (and they are cheap!) It's what I generally use. Also try AF4K.COM (no connection to either outfit). Yep - one doesn't forget CW, just have to clear some rust out occasionally...
Hartley: Nice photo, ready for inspection!...But you DO show the GRA-71 code burst kit, approximately in the center of the photo, below the receiver/transmitters. It's all there. Those gas generators are different though. Interesting.
That website
www.n6cc.com is mine. It's where I've been putting my research on these sets plus recent photos of boondocks ops with mine. There is also a post on the RS-6 set if you are familiar with them too. Similar capability as the '109 but a lot smaller and lighter.
It all works!
