The 55G-1 uses a single FET, and works on two bands, 200 to 600kc and 600kc to 2mc. It came in a cabinet which matches the style of the 55S-1. A small speaker is included. The 55G-1 is pretty rare, and may cost almost as much as the receiver, depending on condition. If your receiver is totally dead below 2 mc (i.e., you can't even hear the 100 kc calibrator), V10A or V16A may be bad. (Both are 6EA8 tube sections). If the previous owner used the 51S-1 receiver with a 55G-1 tuner, he would have cut the internal link between J13 and J14 (RCA connectors on the back panel of the 51S-1). Try plugging in a patch cord between J13 and J14 and see if that helps. 73, Ed Knobloch ritchi50@optonline.net wrote: > Help: Collins 51S-1 No rx on 1 band > Hi > I just received a MINT Collins 51S-1 > and I tried all bands on receive and all work great > except the AM broadcast band 77 ABC etc. > All other bands are fine?

But yes, external modulators seemed common at that time, and maybe for a longer period. When the US Novice license came along, it made a certain amount of sense to have the modulator external, so the rig was initially cheaper and you didn't need a modulator until you upgraded your license. An external modulator was also a way of dividing the weight. Get the heavy modulation transformer out of the main rig. But from reading of material from that period, nobody seemed to be plate modulating an SSB rig.

And depending on the high level balanced modulator, it just might be plate modulation. You put two high level balanced modulators at the output of what amounts to a CW transmitter. The balanced modulators knock out the carrier. Then you use the phasing method to knock out the unwanted sideband. No commercial rig did it this way. I'm not so sure any homebrew rig did it. But it is within the realm of possibility. Certainly, there were a fair number of articles for high level balanced modulators so you could take an existing rig and output DSBsc. It was far easier to add such a stage, or modify the output stage of an existing transmitter to make it a balanced modulator, than to put in a low level balanced modulator and then linearize the rest of the transmitter.

They said if you unbalance the pot in the KWM-2 "carrier balance" circuit (on the right front side, on top of the chassis), but leave the trimmer capacitor alone, you can get about 90mA of plate current due to the carrier, about 15W out with the rig in SSB position. Keep the mic level down so the plate current barely flickers on peaks, and you will be transmitting a.m. with one sideband. Return the pot to its original position for SSB use. Chuck Scheuers said he tried it and that it works. QST had a better method, reinserting carrier after the mechanical filter, by adding it to the PTO output using a variable pot for carrier level control in place of the headphone jack on the front of the KWM-2. See June '63 QST page 48. (A correction appeared, that turret connection E40A should read E20A). The relay connection information in the article applies to the older, non-plug-in relays (Winged emblem KWM-2). Relay K4 shorts out the carrier injection during receive. With this method, you should run 120mA carrier plate current, and will get about 25W carrier out. 73, Ed Knobloch Article: 99746 of rec.radio.amateur.boatanchors From: ritchi50@optonline.net Subject: WTB: Nye Viking MB-VA Antenna Tuner Message-ID: Date: Fri, 26 Aug 2005 17:11:57 -0400 WTB: Nye Viking MB-VA Antenna Tuner Must be in good working order.

For my old but servicable Tek 547 I acquired a Tektronix/Pentrix/Spectropulse spectrum analyser plug-in. This 1 - 10.4 GHz unit appears to give way to much vertical deflection signal to the scope, the scope itselfs works fine with a 1A4 plugin and is thus probably OK. Although I have the manual, it appears there are some schematic sheets missing: I only have sheets 1 and 2, which don't describe all the circuits, so there must be at least one more sheet. The manual says up-front it is for type L20-L30 . This forerunner of the L30 has still a continously variable dispersion knob, rather than a calibrated switch, and has the frequency display in the upper left. On BAMA, I only find the manual for the later L30, which is electronically a very different unit. Who has the missing schematic pages for me, and who knows what might be wrong with the unit?

What the original source frequency was is no issue as to what the original supply PUT INTO THE CIRCUIT. The 400hz supplies only cared about the INPUT voltage and frequency.

The machine comes on, I get a display, all leds for frequency bands are on, Iguess that only FM, default, or the last band selected should be on) half of them dimmer than the other half. Can repeatedly turn radio off and on if no other function/button is selected. If I push a button of two, I can neither turn the machine off, nor select any other bands, have to unplug... 2. When the machine sits a bit, off (power plug attached) It comes on, and now I am even able to tune a bit w/ the encoder, and even key in a frequency, and it changes, and plays a bit, then dies...Letting it sit a couple of minutes, it can be switched back on, and tunes and plays a bit more, starts to growl...and then the sound stops, its stuck and I turn it off.. While I'm not even a mediocre tech, it sounds like a cap is initially empty, charges, then starts to leak...IIRC, a power supply cap, or drop in ps voltage might be might explain the growl..... Maybe the same in the 5v supply? Or should I freeze spray the thing??? The radio uses, AFAIS, among others, M5840 cpu MM5481 led driver?

Power isn't getting to where it should be. The supply rails somewhere are too low. >While I'm not even a mediocre tech, it sounds like a cap is initially >empty, charges, then starts to leak...IIRC, a power supply cap, or drop >in ps voltage might be might explain the growl..... >Maybe the same in the 5v supply? Or should I freeze spray the thing??? Get out the meter and start checking the power supply voltages. After checking them AT the supply, start checking them in other places because you may well have a cap that is intermittently shorted and pulling down the supply rails. Also feel around with your fingers and see if you can find anything hot. One trick I like for finding bad decoupling capacitors is to bridge a large bench supply across the supply rails. If a cap is partially shorted, the high current suddenly available from the bench supply will usually make it fail catastrophically. Note that it DOES sometimes take out board traces so be careful. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis."

If you come thru Gaffney, SC on I-85 there was fuel at $2.65 (as of 2 PM 8/31) on exit 92 (Pilot and Petro). I notice a lot of spaces that had not been taken at Shelby (I was over there today putting up my tent). There are quite a few campers there as always, and more will prolly arrive tomorrow.
