kist2001 0 Posted August 6, 2010 Report Share Posted August 6, 2010 (edited) I want to replace my RF can with one from DPCAV. Unfortunately the pinout is different. Is there anyone who has done this before? Thanks, Ken This is the comtech RF can. Mine has a different pinout. Edited August 6, 2010 by kist2001 Quote Link to post Share on other sites
Mr.RC-Cam 129 Posted August 6, 2010 Report Share Posted August 6, 2010 There are countless Comtech tuner clone knock-offs and a variety of pinouts are found on them. So, post a clear photo of your old tuner and label each wired pin with the voltage you measured on it. That way we can figure it out. Quote Link to post Share on other sites
kist2001 0 Posted August 7, 2010 Author Report Share Posted August 7, 2010 (edited) Being like Scarlet O'Hara I depend upon the kindness of others. Luckily Gary Evans has done the same mod and had the prescience to take a photo. Thanks so much Gary. I think they keep the ribbon cable standard so they can include whatever RF deck is cheapest that week. Edited August 7, 2010 by kist2001 Quote Link to post Share on other sites
Mr.RC-Cam 129 Posted August 7, 2010 Report Share Posted August 7, 2010 The receiver seen in the photo is an authentic TR-1500 (not a junk clone) and the PCB & cable on this model has been the same for several years. But, I have seen three different tuner modules used in it. Glad you got the transplant installed. Quote Link to post Share on other sites
kist2001 0 Posted August 7, 2010 Author Report Share Posted August 7, 2010 Odd that my oscillator mod worked well until now. I don't think I cleaned the flux off the board well. Perhaps it was just gremlins. -Ken Quote Link to post Share on other sites
