Have you looked at Farnell, Mal? There are several pages of rectifiers in their catalogue. Perhaps 365-932 might fit the bill. It is 70A with max 100V. But there are others. In a recent message, mal
I have always had good service from Quartslab, Laurie. They use to advertise in RadCom but they still have a website at http://www.quartslab.com/ Prices and service is very reasonable and they do ser
It's G4DMP, Mal. I tried to get G3DMP but the Ministry of Posts & Telecommunications of the day would not let me have it as I could not find his next of kin. 73 David G4DMP / G3KEP -- +- - - - - - -

I have the data sheets for the BTY95 and BTY99 from the Mullard Technical Handbook, but they are Thyristors if that is a clue. 73 David G4DMP -- +- - - - - - - - - - - - - - - - - + +- - - - - - - -

I was somewhat disturbed by the piece in last Sunday's GB2RS news that gave preliminary information about the proposals to WRC-2012 for an allocation near to 500kHz. It states that the initial propos
But very few domestic broadcast receivers can be described as 'good', Warren. Even so, I can't imagine any receiver with an IF of 470kHz having an IF rejection of 60dB at 472kHz. If we do cause QRM t
Many thanks for your comments, Jim, and for the detailed background explanation. I just felt we should be aware of possible potential problems. There could be many AM radios (or wirelesses!) still ar
Bear in mind, Chris, the rest of us are subsidising you and other UK radio amateurs who are non members of the National Society. Negotiations with Ofcom, IARU Region 1 and the ITU (WRC2012, etc) do c

I see that the announcement on the Ofcom website is merely a copy of what is on the IARU Region 1 site. But there is space for comments to be entered on the IARU site. Let's bombard them with questio
Hm.. It was earlier. They're obviously still working on it. Perhaps there'll be an announcement when GB2RS news appears later today. David Link not working for me, even copy & paste. 73, Gary - G4WGT
I don't see why not, Dimitris; my 501-504 kHz transmitter uses a 6AC7 Clapp VFO - 6AC7 untuned BA - 807 PA to a once conventional pi-network output. The VFO is in fact an old top band VFO with the co
My 5 MHz NoV states from 20 December 2012 to 20 December 2017. It would seem they have recognised the anomaly and changed the dates to 1 January. Anyone applying for an NoV now should have the correc
