I want to see what 70cm is like now. It may have become a lot noisier than 4 or 5 years ago when I last had 70cm 'DX' capability.
Ideally I want to build a new 70cm transverter, but before expending (more) time on the development of a transverter I though it might be better to just connect up my TS2000 again, but with a PGA432 preamp to lower the noise figure to something a bit better than the TS2000 can achieve!
I have a reel of M&P 15mm flexible coax and that ought to allow me to mount the preamp in the shack, initially, and yet still achieve a reasonable system NF.
I also have a 500W SSPA for the band, so that ought to help any DX hear me. However, driven by the TS2000 it is limited to 350W max out or 200W for a good IMD due to the poor TS2000 TX IMD. The SSPA was originally designed as a TV transponder amplifier.
