Pete, I gave Garey a copy of the 34NB kit that Drake sold for wired install to the TR3 and early TR4s. I have the electronic copy somewhere, and I think Garey has it on his CDs, but am not sure. I seem to remember that it had a picture of the PC board, so it might be fairly easy to fabricate. About the only hard part would be any toroids. Seems like it has 2 or 3 of them. I could guess resonate at the IF freq, but not really sure.
If you are serious, I will try to look up the electronic doc and get it to you. 73, Ron WD8SBB --- On Tue, 10/6/09, RadiosRUs <[email protected]> wrote: > From: RadiosRUs <[email protected]> > Subject: [Drakelist] TR-4 Noise Blanker question > To: [email protected] > Date: Tuesday, October 6, 2009, 9:38 PM > > > > > > > > > > > This may have been covered before; but ... has > anyone ever hand built a > noise blanker using the Drake schematic and installed it in > a TR-4? > > Pete N6QW > > -----Inline Attachment Follows----- > > _______________________________________________ > Drakelist mailing list > [email protected] > http://mailman.zerobeat.net/mailman/listinfo/drakelist > _______________________________________________ Drakelist mailing list [email protected] http://mailman.zerobeat.net/mailman/listinfo/drakelist
