Which VHF Modulator for FotH TV - UK Vintage Radio Repair and Restoration Discussion Forum

PJL · 15th Feb 2007, 12:02 am

I was interested in getting a FotH install working and have taken a look through some of the threads in this new section in search of a VHF modulator design.

The FotH TV webpage points to a general discussion thread but would it be possible to pull together a list of links to the various designs? I found mention of Darius's design, David Robinson, David Looser and the one on the ETM site but only links for DR and ETM....Peter

David Looser's design is here :-

Another modulator (our very own Ppppenguin's - Jeffrey Borinsky) is here:-

Can you post the links you have for the DR and ETM designs ? I can build a list and put that in the archive area.

TTFN,

This reminds me that I have a modulator sitting around doing nothing. I think it belonged to the late Pat Hildred and it looks like it's based David Looser's design and built on a PCB. Complete with mains power supply and built in a metal box. Since it's doing nothing here I suppose I ought to sell it to somebody who needs a modulator. This really belongs in the For Sale section so I won't continue here but if anyone wants to PM me....

Various links I found relating to VHF modulators:
Darius UVB: https://www.vintage-radio.net/forum/...=vhf+modulator and http://bs.cyty.com/menschen/e-etzold.../uvb/uvb_e.htm
Darius London & Birmingham: https://www.vintage-radio.net/forum/...oto=nextnewest
System A: http://www.thevalvepage.com/projects...at/modulat.htm
Early Television Museum: http://www.earlytelevision.org/405_modulator.html
David Robinson: http://homepage.ntlworld.com/david.robinson3/

From reading some threads I am not sure if I have picked up all of Darius's designs though...I see David Loosers design is my System A.
