First steps on 3cm band
Two years ago in 2014 I bought from an Israeli surplus store an Eyal-Gal unit, model 6075 with range 10.0 – 10.85 GHz. This module has a LNA and a mixer for the RX path and an amplifier with huge gain and discrete power for the TX. It needs few other parts to become a complete transverter: local oscillator, mixer, bp filter and two relays for the TX/RX changeover. For the local oscillator I used a 100 MHz OCXO with a crystal at 99.36 MHz, manufactured by Eisch-Kafka Electronics, as a reference for a PLL-DRO to obtain 9936 MHz. This permits to convert 10368 MHz to 432 MHz and use the FT817 as IF.
Here the module tested in RX and TX in the LTG lab:
Finally this summer I had the time to install the dish on the roof, an old tv-sat 85cm dish and a feedhorn.
I still need some parts to complete the TX section, but at least I can receive and testing the band.
For now I received 4 beacons directly IQ0RM/B JN61fw, IW0REF/B JN62hj, IQ0AH/B JN40qw, IT9CIT/B JM67lx and IQ5FI/B in rain scatter.
