Title: Signal Shifter to drive BC-610E Post by: Steve W8TOW on July 06, 2012, 05:19:09 PM Just wondering the thoughts out there on
driving a BC-610 with a Signal Shifter (band switching version)... Rather than injecting the VFO signal at the XTAL input, how about pulling the 6L6 and dumping the VFO sig through the 6L6 tube socket (using a 100 pF coupling cap to block the DC...) Anyone done this before? 73 Steve w8tow Title: Re: Signal Shifter to drive BC-610E Post by: W7TFO on July 06, 2012, 05:28:57 PM I get your drift... ;)
Anyways, there are several SS models here for my projects, and any of yours ought to work just fine. They have a good 5 Watts or so output. I am building a TX with a CV-11 (sort of a V-70D type) IPA, and that is plenty of drive for that triode. 73DG Title: Re: Signal Shifter to drive BC-610E Post by: W3GMS on July 08, 2012, 11:43:17 AM Just wondering the thoughts out there on driving a BC-610 with a Signal Shifter (band switching version)...

Keep in mind the Signal Shifter's earned the nickname Signal Drifter for good reason. Some are really quite bad in the drift department and others not so bad. I have a couple of them around here but never examined all the reasons why the beast drifts. I am sure things could be improved once the analysis was done. Its a neat classic beast and good luck with mating it up to your BC-610E. I have a 610E and its a great classic rig! 73, Joe, W3GMS |
