I don't have much in they way of microstrip design software, and the learning curve is too long to start playing - especially at this time of year, so: Is there anyone so au-fait with a microwave / mi

Folks, I got back from Prague early this morning. This was a terrific meeting and even though we think we know all the answers, I learned an awful lot of new stuff! The next of these truly internation

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

An item left behind from last Sunday's FRARS Hamfest is shown in the attached pic . It is , I think , a MM downconverter , but from what to what ? The free running LO , green trimmer and 3 turn coil w

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

Hearing this beacon here in n.e. Norfolk every 10kHz for a fair distance either side of it’s intended frequency. Suddenly went off whilst typing this. Presumably the heat and deliberately turned off r

Hi all, if anyone is interested Bob G3VCA has two wimo 44 ele plus phasing harness for sale £80 (very cheap!), located Gamston (DN22), PM me and will pass details on. thanks Andy G0FVI

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
