I'm looking for a good condition used a WR90 waveguide load (8.2 to 12.4 GHz) with a low reflection coefficient. Something like an HP X910B Has anyone got anything? There's a few tatty ones on eBay ht

Now having a decent sig gen I have just tested the LNA for 23 I have, and find its 23db gain, that and the 20db off the Kuhne gives me quite a bit of gain, not sure of NF on LNA though. I thought of u

All, I use a G0MRF designed 739-144MHz downconverter for QO-100 RX. Uses a 595MHz pre-programmed LO. Has anyone tried a 307MHz LO for an IF of 432MHz ? Same IF I use with my uplink transverter. Other
