Hello all, One of my friend got that amplifier as surplus.. I am just thinking about buying this from him but, first I need to be sure if this is something that I can use. I googled some but couldnt f

Been going through my sma relays and testing them on my primitive spectrum analyser has shown that I have quite a few lossy relay on TX as high as 4dB and quite a few showing around 1dB on RX side. I

Lurking in my scrap is a sheet of Rogers duriod , double sided ...... about 8 inches square The lable is a bit faded , but I can make out D-5880 I think 2 oz copper thickness , top to base on my verni

GB3KBQ is romping in here now from 340 km away, even with my dish rather low. Anyone to my south-west fancy a quick try on Q65 or CW or phone? I'll be on KST for 20 mins or so Neil G4DBN

I have a problem with my RSP 1 .It manifest itself when I was checking the spektrum of the new GB3KBQ beacon. Using a 144 MHz IF, I enter 144,870 and via the tranverter see a single signal on .870, ho

Having bought a 10Ghz Hempt LNA I find its u/s. MGF4917D What should I be looking for to replace the device? nothing on ebay. Ben

Anyone know of a source of small bolt in ir solder in feed through capacitors. 3-4mm diameter max as I want to externalize some control pins on two transverters I have. All the ones Ive seen on Ebay/B

All, I have some MGF4919G’s and I will need to make a 10GHz LNA at some point. (a) Could someone point me in the direction of a design using said devices please ? Thanks Colin de G8LBS Sent from Mail

I have a couple of Transco transfer relays type 707C70200 . I also have a chart from Dowkey Transco that shows the power handling for their 700 and 710 series SMA and plotting average power input in w

There was a thread a while back about lathing relays. The ones I had required a voltage, they latched then pulled no current. One's I have just got need volts to latch then pull about 100mA if volts l
