[AMRadio] Mod Reactor
I have a mod reactor from an RCA BTA-1R1. I think it's 50 hy @ 600 ma. It has some surface rust on the exposed metal, and some of the paper on the outside edges of the winding has separated at the top in bottom, leaving gaps between the paper wraps. I want to get the surface rust off, and fill in the paper gaps and repaint this thing. What would be a good material to dope up these gaps in the paper before I repaint it? 73 Brian / wa5am -- Money is only temporary, radios are forever - Jim Little aka the old dawg/K5BAI __ Our Main Website: http://www.amfone.net AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.

Peter Markavage wrote: You said: Explain to me why CW is no longer a requirement for a Ham Radio license This question really should be addressed to But, it wasn't. You beat the ARRL drum rather loudly, Pete. I (and others) have been saying the same thing about the ARRL and the YeaCommWood bunch for a while, now. The manufacturers whine and complain that they are not selling enough radios. They strike a deal with the ARRL (need I remind you, that the FCC consideres the ARRL as being -the- voice of Ham Radio?) and give them 'x' amount of dollars if they lower the licensing requirements so more people can become hams and they can (*gasp*) sell more radios. Pure economics 101, with some back-room lawyering going on. YeaCommWood tells the ARRL here, we'll do -this- for you if you'll do 'that' for us, the ARRL slips the bribe in their pocket and then rares back on it's hind haunches and tells the FCC that Amateur radio needs to do 'this and that', gets it done, and now Johnny Novice no longer has to draw a schematic of a transmitter, he can chose from multiple guess answers, or Johnny Novice no longer has to know CW faster than 5wpm to use Voice on HF, or (latest) Johnny Novice now no longer has to know CW at -all- to get a Ham License and it's all done, Pete, in the name of 'selling more radios' so that the 'shack on a belt' crowd can spend their money on the new YeaCommWood radio that costs as much as an economy automobile! A 5 digit price-tag for a SSB transceiver? For that kind of money, the damned thing had better grow legs and change the cat's litter box! ;-) I bet the SSB crowd would love to hear carriers with digital signals riding over them. I'm all for 2.5kc of deviation and FM as a viable mode on 75m, when signals warrant and selective fading doesn't totally screw up the signal. Jim/WD5JKO (of this list) had a problem with RFI in his telephone, and he switched from Amplitude Modulation to Phase Modulation on his QRO'ed CE-20A. I couldn't hear much difference on my receiving end, but his claim was that there was no longer 'other voices' in his wife's telephone conversation.

Most of the transformer leads are brittle and even carefully removing them thru the chassis hole, I can feel the rubber inner jacket breaking up. I would expect to replace the wires near as I can get to the windings. The plate transformer will need good HT wire. I have quite a bit of different sizes of silver teflon. for most of the windings but not quite sure what to do about the HT wires. This is a project transmitter, not a restoration. Suggestons? Sources of suitable wire in an affordable put up. I have other large transformers with the same problem as well.

Re: [AMRadio] Transformer Lead Dress Dave

That works for minor cracks and breaks in the insulation but these leads are so brittle that replacement is called for especially with the plate transformer at close to 2kv RMS.

Re: [AMRadio] Transformer Lead Dress Dave
They do make a shrink tubing with a type of sealant inside. We used to use these when I worked at Babcock Wilcox. They are somewhat stiff but I think it maintain insulation at 2KV potential. Mod-U-Lator, Mike(y) W3SLK That works for minor cracks and breaks in the insulation but these leads are so brittle that replacement is called for especially with the plate transformer at close to 2kv RMS. Heat shrink is also not very flexable but I might use it for the LV transformer and choke. I'm going to be turning this VK II chassis into an externally modulated RF deck. __ Our Main Website: http://www.amfone.net AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
Re: [AMRadio] Transformer Rewind
The input coil is common to all bands in the 75A1, the secondary is then fed to the band switch. Check the antenna coil primary first and then the secondary for continuity. Rewinding shouldnt be that hard if the form hasnt been destroyed. The hardest part will be removing it from the assembly.

Rewinding shouldnt be that hard if the form hasnt been destroyed. The hardest part will be removing it from the assembly. A couple of decades ago, I accidently dumped a few hundred watts of RF directly into the front-end of an SX-73, on 75m. The input coil took the brunt of the damage. John Mohn/W5MEU(sk) told me to come out there and get some 24ga copper wire to re-wind that coil. Very carefully, I removed the phoenelic board from the turret in which the coil was installed, then ever so-much-more carefully, removed the coil from the board. There was a spot on the coil that -wasn't- burnt, so I was able to count turns, and re-wind the coil. Luckily, I was working at Southwest Research Institute at the time, and was able to utilize a small-wattage iron, some organic stripper and a magnifying glass to re-solder the connections. -- Driving your AM Rig without a scope, is like driving your car at night, without headlights.

[AMRadio] FS: Rack Panels, Used Chassis, Cabinet Sheet Metal
For Sale. All prices plus Shipping Cost. 19 Inch Rack Panels. These are all heavy-gauge panels suitable for front panel component mounting. 3.5 inch, aluminum, scratched gray paint. $5 5.25 inch Bud aluminum, black wrinkle, NOS in original wrapping. $9 5.25 inch steel, painted gray. $7 8.75 inch, steel, gray wrinkle, 4 1/8 inch holes near edges for chassis mounting and one 3/8 inch hole dead center where the chassis would be. $7 8.75 inch aluminum, scratched gray paint. $8 Three 10.5 inch aluminum, natural finish protected by stick-on paper. $10 each Two 14 inch aluminum natural finish. These were back panels and they have a small notch cut in one edge for a line cord exit. $8 each 17.5 inch Bud aluminum, natural finish, NOS in original wrapping. $15 Chassis and Boxes, Mostly Used 17x10x3 black wrinkle chassis. This may have been a commercial ham TX or early kit that someone cannibalized. It has 3 tubes sockets mounted--4 pin rectifier, 5-pin and octal. The power supply components--transformer and electrolytic are mounted. The front chassis apron has an on/off switch, pilot lamp, var cap, octal socket, hole for a meter and 1/4 inch jack. The back chassis apron is clean except for a line cord exit hole. Two ceramic standoffs on the center-rear of the chassis are apparently for antenna connections. The wiring suggests a one-tube CW transmitter in the 6V6-6F6 class, or maybe octal sweep tube--6BG6? The 5-pin socket is for a plug-in coil I think. Maybe someone wants to resurrect this? Or just turn the chassis around and make the back the front for a new project. $10 5Dx10Wx3H Bud aluminum chassis, NOS in wrapping. $8 7Dx12Wx3H thin aluminum chassis with gussets at the corners. Someone started a project. They mounted a crystal socket, 9-pin socket, octal socket and 2 pots all facing up on the chassis. Underneath, they mounted one ex-ARC-5 cap and one small Thordarson transformer of unknown utility. The only thing mounted on the front of the chassis apron is one DPDT switch dead center. As-is. $7 2 plastic radio shack project cases, NOS. One is 4 x 2 x 1. The other is 8x3x1 with aluminum front panel. Both: $4 5x7x3 Premier aluminum chassis, NOS. $5 4x4x2 steel box black wrinkle with front panel, 3 holes in panel plus what looks like 9 sets of 3 holes for BNC-connectors or similar on 2 opposite sides of the box. Nicely drilled. Some sort of switch box or combiner. Free with any purchase. 4x6x2 aluminum chassis, one RCA jack on one side and two on the other, 3 RCA-jack size holes on top plus a bunch of 3/16” holes. Free with any purchase. 7x12x3 thin aluminum chassis with braces at corners. 2 7-pin sockets and 2 octal sockets mounted on to plus many 3/16 inch holes. Apron has SO-239 and 2 3/8 inch holes on one side and line cord exit on short side. Sloppy work. Some parts mounted underneath. $4 17x10x2 thin aluminum chassis with gussets at corners. NOS. $8 Cabinet Sheet Metal. Someone went to a lot of cutting and bending work to make 3 sheet metal “cabinets” that would mount right onto the chassis, leaving the chassis apron showing as part of the front panel. These are cut and bent and partially drilled for the screws necessary to hold them together. Top quality work and medium gauge, strong metal. 1. Top, back, sides and front for 17x10.75x3 chassis. Undrilled. $9 2. Top, back and sides (no front) for 17x12.75x3 chassis. Drilled. $8 3. Top, sides and back (no front) for 17x12.75x3 chassis. Undrilled, Back piece seems cut a bit too long or maybe I figured it wrong. $5 Thanks for looking. 73, Don Merz, N3RHT __ Our Main Website: http://www.amfone.net AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
