[AMRadio] Stock or modify? BC rig value
In the discussion about RCA transmitters I picked up on the comment of Neal/CAF -- I feel the Rig has more Value if kept close to Factory origonal. Value to whom? Branching off Rick's situation for a moment to try to get your thoughts on a dilemma. Several people have asked me, over the past 10-15 years, whether it is better to preserve an old broadcast transmitter as-is or modify it to make it more useful in a second life on the ham bands. I wholeheartedly say modify it ! Radio stations are throwing out transmitters like this, and replacing them with little rackmount MOSFET jobs that plug into a standard AC outlet. Change the filters on the muffin fans, and settle in for years of no-maintenance service. Occasionally a station will decide to get rid of a Gates, an RCA, or other fairly common transmitter of the late 1940s and 1950s, and they will start high with their asking price. There's one just like Rick's asking $3000 right now in an industry newspaper. But far more common is the scenario I've mentioned -- word will go out a station is freeing up space, getting rid of an old transmitter that the new engineer can't fix. Out the back door, come get it, yours for the taking. Modifications performed in keeping with spirit of the original quality of design seem warranted to the prospective ham as a way to continue to obtain the most useful service out of the transmitter, to provide greatest enjoyment to those of us on the other end receiving a classic signal like that, and perhaps best of all, settling the question of what to do with a 1000 lb beast if it is to be saved from the landfill or the scrap metal yard. THAT's why converting a BC rig to 160-75-40 is a valuable upgrade, in my opinion. Paul/VJB __ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
[AMRadio] 10 Meters
Well I want to apologize y'all. I'm a ten meter NUT and was reading the postings yesterday, but my bride had plans for me that did not include ham radio LOL I will be listening today, on 29.025 give me a scream! My Ranger will pump out a whopping 40 watts, but I'll have the Globe King 500 tuned up there too for the heavy work ( though it does not like to work on ten real well ) Hygain 5 element DX long john at 82 feet.. ten meters is callin! ronnie
Re: [AMRadio] BTA Mods
Steve, That could very well be true. When I receive the schematic I'll know more about exactly what the work is all about. There are very few differences between the BTA models circuit wise, but it seems the oscillator is one of them. The BTA-1R1 uses 4PDT AC relays to switch the crystal frequency and the R2 I have uses DPDT reversing latch relays with DC coils. I'm not sure exactly what else is different, but I have found some of the edge connections to be different. Thanks for the insight. 73, Rick/K5IZ Perhaps someone needed more capacitance to net the crystal on frequency... and two of the three crystal sockets more or less taken out of use Perhaps someone cut out the Conelrad crystal switching... Steve WD8DAS
Re: [AMRadio] BTA Mods
Neal, Thanks so much for the insight and advice. I think first hand experience and advise from that experience is most valuable. Larry Will, another fine engineer, has also given me some great advice and help. Hopefully, with the things I've learned thus far and the help and advice from you guys who have been there and done that, I'll be able to get this old gal back on the air. I really don't want to make any major modifications in the layout or circuitry if I can help it. I have always thought it a great challenge to retain the original design and layout while achieving my goals. Whether it will be possible in this case remains to be seen. I'll keep you guys posted on my progress and I'm sure I'll be tapping into your vast experience for help and advice. 73, Rick/K5IZ neal Newman wrote: Hi Rick No matter what I tried to Fix what was done to this transmitter. It would Put out Spurs all over the place. Yes It got to 75 meters...looking at the spectrum analyzer It was all over the place. these spurs were causing High currents and arcing. in the output Network. self oscillations the transmitter was what I call a Runaway. you Could pull out the crystal and it would still deliver full output Not a Good sign.. thats when I decided to Build the output network back to the RCA design. and try 160 meters.. it worked first shot. Clean spectral. If you like to Tinker with High voltages and networks. and not worried about Blowing out coils. Cool Go for it. I would recommend you put a spectrum analyzer on it when your Done. best to cover your butt.. and If you Do get a clean Output on 75 meters. Let me know Ill try it on another Rig I just picked up.. Now I know the Gates BC-1H can go to 75 meters I know one down south where its a dual bander it does 75 and 160 meters. going through a Divorce right now. so eventually Ill get to working on the Gates..
Re: [AMRadio] BTA Mods
That is interesting about the relays Rick. Are you sure they are DC coils? I have a PB LK 17A relay here that NIB. It is the same setup but has 115 V coils. They are marked AC but I wonder if the BTA ran them off of DC? 73 Jim W5JO Steve, That could very well be true. When I receive the schematic I'll know more about exactly what the work is all about.

Re: [AMRadio] BTA Mods
Hi Jim, I don't have the schematic yet, but the input to the trace on the board that goes to the coil goes thru a rectifier diode then on to the coil. The relays are both marked Potter Brumfield SL4349 Reversing Polarity Latch. I have been unable to find any information on the relays themselves thus far. They are very small plug in type relays and the diagram on the case indicates they are DPDT. I have not tried to power the relays to see if the contacts are working properly since I'm not sure of the voltage of the coil. I am assuming they are 115 v, but I don't want to chance it. 73, Rick/K5IZ Jim Wilhite wrote: That is interesting about the relays Rick. Are you sure they are DC coils?
