Funbiz, These pics are of amps I have built in the past. I have lost track of them over time. Your in Miami huh? What type of gear are you running. Ghost Rider??? Here are pictures of a 2 tube 8295 mobile box I made for Ghost back in 88 before he built his own amps...

Shoemaker, I'm not sure who made that but it's 5-6 watts max drive (carrier). Output (carrier) should be at least 250-350 watts or better. Both the 21 and 23 JS6's should work, the first number denotes the filament voltage. It wouldn't hurt to measure the exact voltage across a single filament...

That thing is clean…. It’s been a long time since I have seen one of them. That was one of the very first amps I saw in use back in 72-73 when I was just starting out. Brings back some memories. Those amps are almost obsolete today, so it’s not worth spending a lot to fix them. But if they...

That power supply used 6 Peter Dahl transformers each hooked to a 200 amp Leese, each trans had its own rectifier board, all in parallel. With two 5kv oil caps and 220 watt bleeder resistors. Max power output; almost 30-kw’s with 30 watts drive! I have more pics…. I just need to get them...

What’s up skater? I just discovered this thread, I am just getting around to exploring other parts of this site, guess I got a little lost in the antenna section. I almost forgot that amp building is my true calling! Lol I was talking to Coily on another thread about making steel whips come...

I hear ya, I takes an open mind and imagination to bridge to certain ideas. At least you have been vindicated on that point and have at least one ally. I agree 100%. I have always admired those guys “genius”, and the antennas they designed. I don’t think we have anything like that today...

I agree with Marconi that is a cool story. What’s better is he’s agreeing with what I said. He talks about the coils inductance and matching to ¾ wave. He does not mention loading per se but calls it matching instead. But make no mistake that is considered to be loading, and in this case base...

I couldn’t have said it better myself. Chief, This is correct sir…. However, what you call a “loop” is a coil, is a inductor. BUT As we know 5/8 of a wave does not self resonate on 27mHz, that coil at the bottom just happens to be close to a 1/8 wave (65 inches) long and is needed...

Doc, That’s a good point, in the case of the tapped coil like the V5/8 and Jays I10K, I think your right – it is more of impedance matching device. However on a Sigma 5/8 old design, it’s just an inductor in series with the connection to the element – isn’t that base loading? No, I never...

I think anytime you are testing for gain, the greater the distance you use – the larger the difference will seem to be. I think most people would agree on that. But this presents a problem??? What distance should we use as a standard to compare antennas? What is the best distance….1…5….10 or...

Scott, you have misunderstood something somewhere. I am not sure what you are asking?? Suffice it to say that the 2 dB increase was shown in both positions. I simply did not mention what the signal was in the low position I just said it went up 2 dB. Dr. DX, No such radiation anomaly exists...

For brevity I did not mention the signal at the low position. The difference from low to high position was ½ s-unit (2dB’s). The 8 s-unit (Maco) signal was at the high position. As already mentioned the receiving antenna was 20 feet above ground. The 2 dB increase in gain was noted at both the...

It's funny you say that....cause I do!! When I was a kid, the only thing that attracted my interest more than radio was High Voltage! Images of: Jacobs ladders, Tesla Coils, and Van De Graffe generators were in my head at all times. I was obsessed with it........Dude!!.......I got some stories...

Mr. Coily, I wasn’t using one on that antenna…… I wanted it to arc!! Wolf

FOR IMMEDIATE RELEASE!! Test results from the comparison of a Maco V5/8 to Wolf P64. Residential installation. During the afternoon on 1/28/06 a fellow radio enthusiast, located 8 miles away from the shop - changed antennas. The test was conducted on 27.365mHz with a un-modulated...

Railroad tracks are definitely conductive, the tracks around here are bonded together with steel cable. Eddie, it sounds like you’ve got a giant piece of ferrite lol. Have you tried grinding away some of the surface and taking a ohms reading on clean metal? Doc, I wonder what would have...

Doc, I see what you are saying…. I never thought about it quite that way – comparing one side to other, because that’s clearly what is happening in a forward/reverse meter. I guess in that regard there not to reliable, not to mention they will give a different reading depending where they are...

I was thinking about using a relay, mounted inside the tubing, as close to the insulator as possible, if not inside the insulator. Then using a combination of chokes to decouple the control wire from the rf, and at the bottom where it exits the sleeve. I think the hardest part will be getting it...
