26-November-2019 – my first contact on the 2.30 GHz NoV band

With the SG-Labs 13cm transverter in a box indoors, I can use a sub-band switch on the front panel of the box to switch between 2.30, 2.32 and 2.4 GHz. At 1870 MHz, the LO (Local Oscillator) frequency is rather low for the Microwaves Modules 70cm transverter (1870+430=2300 MHz) as I have not reprogrammed the SG-Labs transverter, so I thought the configuration might not work on the 2.300 to 2.302 GHz NoV band. I had configured the K3 with a 2300 band setting to generate the correct frequency on 10m band Intermediate Frequency (IF) feed to the 70cm transverter.

Using my Tiny VNA as a signal source, I found I could receive in the 2.30 GHz band.

I tried a contact on transmit with Keith G4ODA. It worked easily! Keith’s signal was very strong. I was using the Andrew linear amplifier producing about 50W, feeding the 40 el Wimo yagi through some metres of Ultraflex-10.

Really the SG-Labs transverter needs re-programming to give a more appropriate LO frequency, but it is nice that something works on the NoV band for the time being.

UK radio amateurs can apply for an NoV here for the 2.300-2.302 GHz band.
