I recently acquired a 10Ghz / 144MHz transverter which should get me a little closer to the band. I do still have a kit to build but having this means I can eventually test that as well. It needs a 10MHz reference input and I was recommended one from an eBay seller in China. The unit arrived today and having had it sat on a ‘scope and counter for several hours it does seem to produce a solid 10Mhz signal at a nice sine wave (it has TTL output too). Not bad for £12.
