After a bit of a hiatus I've been troubleshooting my 13cm transverter. For power and return loss measurement I am using a couple of AD8313's with 20dB directional couplers and Arduino sketch that was

Has NO ONE! been active on the GHz Bands over the last month? Just 1 contribution so far... Thanks Paul GW0MDQ! Clearly we need more contests as it's not because it was raining .... (the usual excuse

Has anyone else had any experience with this 40cm Cassegrain dish on 10GHz? With the LNB removed, which isn't so straightforward, it has a standard WG17/WR75 circular flange. Seems OK but don't have m

I've just come back from the garage where I wanted to take pictures of the transverter. As I found out, the 3400MHz trnsverter was lost by the shipping company. The PA and preamplifier for 3400MHz are

Hi All, I will sell all my 9cm equipment to raise funds for another projects. There is a DB6NT MKU34G2 transverter (& MKU XO1 PLL Oszillator with 10MHz input) with Toshiba UM2683B driver and DL2AM PA

As part of my on-going experiments in search of 'less is more' I've printed a small adaptor for an offset dish I have spare. Its attractive to use as its light yet large, so hoping to get reasonable g

I have a nice 60cm back-fed dish with a N-type to WG feed labelled as for 6.4GHz. Will it work on 5.7GHz with a reasonable (as in won't harm the PA) match or should I build a new transition/modify pro

I have found what appears to be a beacon signal on 3400.920 with a slow drift upwards Just in between PI7RTD and PI7ALK. It has a very narrow shift and is unfortunately very weak which makes reading t

I just bought some sucoform type RG402 from an Epay vendor. It's the stuff with the blue outer covering. I had previously bought this in 1m lengths but it made sense to buy a 10 metre this time. As i

I have taken GB3MHZ 23cms off air for now, as something had become unstable and was generating sprogs every few kHz right across the band. It is probably temperature related as the beacon room has no

Hi All, im currently downgrading a 23cm amp from water cooled to air cooled. I’ve a new valve in place ,what would you recommend for maximum power output ? I was thinking 75 watts or is 100 ok ? Also

I am currently turning out the boxes of microwave kit I acquired during the days of wideband on 10GHz back in the 1970’s and came across a number of devices I had forgotten about. One in particular is
