Hi all, I have repurposed a DDK 2008 L band source from 96MHz to 106.5MHz with an output of 1278MHz. The original was extended to include a PGA103+ to bump up the output to feed a high level mixer. Th

Back on topic hopefully. I have never objected to paying duty and VAT but I do strongly object to paying £8 to £20 on top of that duty to the courier I already paid handsomely to deliver it in order t

Nice delivery of pcbs today, the 9cm transverter is the one that I'm looking forward to building up. There is another batch of CANFI noise heads, but my pick and place is in bits at the moment, i 'll

Well, having had a guy I buy aerial parts off in Germany decline to supply because of VAT .. I did a bit more digging. It turns out, that while I thought he was wrong .. he's actually right ... any sm

Does anyone have a schematic for an MKU 13 G3? I can’t find mine. I can find the bit of paper that came with it explaining how to fit a lock indicator LED but not the schematic. I just finished puttin

I already have a 50W Continental 432MHz PA, it is very linear. For my new system I need a little bit more power. I understand that there is a 150W version of the Continental amplifiers? Does anyone ha

Is there a plug-n-play design package for microstrip filter design? I know it's a complicated, non-optimum technique, depending heavily on characteristics of the substrate material, yet is one of the

Huge interference on 2m and above in use any ideas. -- Mike GD6ICR IO74PF73TW

Just contacted the PCB suppliers, as, by my reckoning, the 15 working-days is now due (what with Xmas and all that) but it seems there's still another 3 days to go on the schedule, plus a day for disp

All, et al, I have been following with interest the posts re: ADF4351. I have a board with a ADF4350 on it. Its exactly the same layout as many of the green 4351 PCB’s on The Bay. Above. Can I still u

Goodmorning to all, After experiments with Q100 , i' want to take a new step in the microwave region. First step is receiving the ON0EME EME beacon . I made calculations ( with VK3UM EMEcalc and other

Thinking about my new 23 and 13Cm units I might put the psu in a separate box then have sockets for the 15A 28V outputs but was wondering which plug/sockets to use, something that can carry current bu

Does anyone have a pin-out diagram for the above 12volt 5 MHz reference oscillator? (spec No FU00250) Usual searches only turn up 613A which seems to have a different base. This one 7 pin. Thanks and

I have been looking at a Chinese signal source using an ADF4351 and sold for around £30. This one has a large LCD display and several functions and looks to have an SMA connector for an external refer

Hello, Does anyone have a secondhand mast head unit that I would like to attach to a trailer. I am happy to pay the going rate. 73 Dave G4GLT.
