Looks like an interesting project, although the price of the kit is a
bit more than I'd like to pay for what I'd be using it for: talking to
AO-92 on L-band.

I've been looking into something like a varactor-tuned frequency
tripler, as shown a bit over half-way down this web page:
The schematic is here: http://www.sydneystormcity.com/1296%20Tripler.gif
It may not be an ideal solution but considering how often the L-band
experiment will be active on AO-92, I'm looking at a cost-effective

Seems to put out 400mw FM out. I am not able to take time now to review deeper (stealing away from work) but I look forward to parsing through the schematic/links this weekend. I am forwarding this notice for anyone who will be able to get there sooner. I think there is some potential here, and I would like to know other’ opinions.
