David, I generally agree with all your points. However as Amateurs, we need to be a lot more aware of where are spurious / unwanted emissions lie. In the past there has been very little thought of rad

Paul, I disagree with you. Existing equipment is on 122.400 in UK. The frequency is works well when you want to generate markers. 12.240 from an Elcom, or 13.600 x 9 from a low cost synth. It also all

A local farmer uses vhf to link his people, farms and tractors. He has several farms up to 30 miles away. He had good coverage except one, which was in a valley. We used a gain antenna 8el I think, po

In a similar vain to Andy. I have being trying to offload a Carnel Labs NM-67B 1-18GHz measurement receiver. It came out in 2003 as an update to the Stoddart NM-67. Cost circa $60k. It is too big and

47GHz loan gear and WR-15 waveguide
Keith, The info from Francois, is what you need. However I just use the Pasolink x4 multiplier. This driven by 100mW at 11.66xx GHz gives 15-20mW out, when re-tuned. This I use as LO for a wr-28 mixer

I have the 47GHz transverter, which will be the microwave group loan unit, now working. This is based on a Pasolink unit with 25cm dish. It should be good on receive with a fundamental mixer. But, is

One thing I forgot to add to the article in Scatterpoint. Is that they remember the last frequency programmed. So then just a 5 & 12V supply required. Though a lock led to ground via a resistor is use

Toshiba BA2076B amplifier for 24GHz ?
Stuart, The 2076B does not go down to 24G. Neil’s suggestion looks good, I had not seen those before. Riger
