Do any chasers have 4m SSB/CW? My transverter is nearly ready. Invoking Theseus’ paradox in a process rather like the joke about the old broom I have built a G3XBM transverter but;
The receiver section is completely different and the transmitter section will be completely different. And, of course, the local oscillator system is completely different.
The RX has a critically coupled input filter, an MMIC as an RF preamp, a TUF-25S ring mixer
The oscillator uses a BFR90 feeding another (different) MMIC which feeds a magic T power splitter.
The TX (still under development) will use FETS and should have an output of around 5W. It will use two 175MHz Mitsubishi RF FETS (from SDR-Kits).
I have made extensive use of SMDs to allow the complete board to measure just 8 x 10cm.
With a bit of luck I might be in a position to try it out from the shack on Sunday.
