Re: [AMRadio] FS Globe Champ 350
Hi Bob, no it is the one you traded to Mike and he sold it to me. I fixed the VFO and put 160 meters back in it. I straightened the panel and have it going. I changed the Tune cap so it will load into a 50 ohm antenna on 160 and returned the audio chain to the normal tube line up. I rewired it according to a 1950 type audio circuit leaving the bandwidth open. The VFO still drifts a bit but not like it did. Jim Jim is this the one that you changed the finals on???

[AMRadio] Receivers
Somehow, I've managed to hang on to the HQ110A/VHF that my folks gave me for Christmas in 1968. It needs a good alignment job, and will hopefully have that soon. Then, it will be paired with a DX60. Anyone remember the Lafayette HA500? I almost settled for that one, but chose the HQ110A/VHF because it covered both 160 and 2 meters. I also have a recently acquired HQ170 that needs a thorough going through, as it only likes to work on 80 meters. In my earlier days, I started with a borrowed S120. That one is still with its original owner, who had no idea what he was starting when he loaned it to an 11-year-old for the summer back in 1966. For Christmas that year I received a Zenith, the model number of which escapes me, but it had a slide rule dial and band spread much like the S120, and drifted like an S40 on the higher bands. For brief periods I also used an RME4350A, a BC348Q, an SX62A, and an NC300. I also operated the station of a friend several times when he was using one of the "HBR" series of receivers that his dad had built from QST. His dad still has it, and it still works great.

[AMRadio] RE: receiver survey
I have several (hi!) which are awaiting restoration. I'll concentrate on my top running ones R-390A restored by Chuck Rippel, excellent radio, very sensitive and has had audio mods, all around great radio R-388 restored by Al Parker, I use this for receive with my DX-100. Another great radio and it is very easy to get on frequency with it and the dial is easier to turn than a 390A's is, it's not as sensitive however as the 390(A's) unless I have a weak tube. SP-600 also a great radio and again very sensitive and selective, I use this for BCB DXing this one has none of the drawbacks I've heard other ops mention, the dial is right on, it's not hard to find the frequency you're on and it's dial is great, if this radio were a car it would be a Cadillac. HRO-50R1, this is in the original tall rack with speaker and all coils and is black wrinkle, originally came from someone who worked at National which was not real far from here. (Malden, MA) This radio works and looks like new, seems to be on par with the other two as far as performance. This is by far my most collectible radio. I don't think anyone ever used it for any great length of time, I know they guy I bought it from used it for only a few hours in 13 years. I am the third owner. HRO-60T, is also a great selective sensitive receiver and sounds great. I'm missing a one coil for this one I believe 6M. HQ-180, also a great radio, doesn't have the solid expensive feel of the SP-600 however, but holds it's own. I also have several waiting to be restored including 2 R390's and an R-390A, also several SP-400's and 200's. The older Super Pros have great audio with about 12 Watts output and a continuously variable filter that goes from 3Khz to 16 Khz.

Re: [AMRadio] receiver survey
Someone mentioned "what's wrong with the older receivers", and that reminded me of another receiver that I have that I forgot to mention earlier: The HRO-60. The only thing wrong with that receiver, from my point of view, is that one must change coils right in the middle of the BC band. Other than that, it's a wonderful receiver with excellent audio. I have every coil for the radio except one. I believe it's the one just below the BC band. 73, Barrie, W7ALW __ 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.

The later SX-28A tried to address some of the cap issues with removable sub-chassis which helps, but not a lot. Back in the day, it probably saved some time if a bad cap ended up on that particular board. Today you're still yanking the bandswitch shaft and getting in up to your elbows. Probably the biggest thing wrong with older gear today is the inability of folks to understand and work on them properly. We've become too much of an instant gratification society.

For a while, folks referred to them as 'rare', which they are not. They're not as common as, say...the SX-28 or any number of other examples, but they aren't hard to find unless you're looking for $25 examples. What they are is well-built and, as a result, a bit on the pricey side. Well worth it, IMO. I think they're the best Halli receiver, even above the SX-88. But alas, the collectors disagreegood for them, better for the users! The most interesting note is that the SX-73 and SP-600 both came about from the same contract, and share the same basic nomenclature. Until you look under the hood.

Re: [AMRadio] receiver survey
Hi Barrie, What's your take on the SX-88 receiver...? They sure do look attractive enough, but man oh man, do they ever command the big bucks come re-sale time! Is it as good as the dollars it attracts, or is there some kind of mystique / aura surrounding that rig? I sure am curious... That SX-28A sounds like a FB classic, too --- its only drawback, from what I've heard, is the oddball impedance of the audio output transformer for 'phones, & lack of access to specific fixed capacitors because of the switching design of it (like trying to replace a spark plug in certain GM cars with air conditioning!)

SX-42 Nice SX-62B Very, very nice SX-73 Very, very nice SX-88 Nice SX-99 Average TW-1000 and several Trans-Oceanics and other portables from the 1940s and 1950s. R-390Very, very nice 75A4 Nice. Since I am no longer able to lug the heavy receivers around, it's likely they will be for sale soon. Condition listed above. I'm open to realistic offers, before they go on that other place. 73, Barrie, W7ALW __ 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] Hi Current AC connectors
Got to agree with Paul on this. Going to extremes to find these old type connectors doesn't make much sense. Paul points out a good source and if you hit your local electrical supply house, with either your original male ot female plug/connector in hand, they probably would have a very close replacement. A little hole reaming, if necessary, shouldn't be that big of a deal. I believe I remember seeing a small selection of these types of twist-lock connector/plug in either Home Depot or Lowe's.

Re: [AMRadio] Receivers
First let me say that I'm a Heathkit fan and run a DX-100. Due to wanting to primarily use Heathkit products I paired the RX-1 Mohawk as my receiver of choice for AM. Many will tell you it has technical deficiencies but it matches my DX-100 with respect to band coverage. They both cover 160-10 meters where as the physically matching transmitter for the RX-1 is the TX-1 but the TX-1 does not cover 160, which is strange. The biggest fault of the RX-1 is it's drift but on AM which it is a lot less bothersome than on SSB. For about 2 hours the radio drifts frequency quite a bit. With AM you can drift a fair amount and still read the signal but with SSB your hand is always on the dial trying to keep Donald Duck out of your radio. There is a process detailed in a series of articles in ER Magazine on how to minimize the drift but it's too much of a bother for me. I guess it's like driving a Studebaker...you do it because you want to. 73, Tom K3TVC > > From: Kim Elmore <[EMAIL PROTECTED]> > Date: 2007/09/18 Tue PM 09:27:00 EDT > To: amradio@mailman.qth.net > Subject: [AMRadio] Receivers > > Much of the traffic here concerns transmitters.

Re: [AMRadio] Receivers
This was going to be my next question; How might I use a modern rx with a boatanchor tx? I'll have to look at my Orion II Manual again... What a fabulous list of Golden Age receivers! Hat's off to all of you who keep them going! With some luck, at some point somewhere down the road, I'll get my Dad's (W5JHJ) Globe Champ 350, HQ-170A and HQ-110. He's now a Silent Key (in QST this month -- I guess I'll keep that one) and was the original owner of all of these, along with a NC4L-blessed FT-102 (NC4L took it from a miserable piece of junk to a fabulous rig). They are all currently tied up in a very nasty probate, thanks mainly to a career deadbeat brother-in-law and my sister to idolizes his work ethic. But enough of that... Last time we checked, they all worked. Dad had kept them in working order, though I don't know how well they work. I know them all well, so I'm not queasy about rummaging about inside and fixing what needs to be fixed. I think the Globe is in the best shape, followed probably by the '170A. The '110 was always used as a gc rx -- I tried using it once as a primary rx for CW when the '170A needed some work. I found it totally inadequate. Maybe I'm spoiled, but it drifted, tuned way too fast, was microphonic, and didn't have sufficient selectivity. It was much better for 'phone and seemed fine for SWLing. Both the '170A and the '110 have muting lines, and Dad has an appropriate relay set up to mute the rx when the tx is keyed. I know that's all still there, so when the time comes, shaking the dust out should be pretty straightforward. I'll look to see if my Orion has a muting line (or anything similar). 73, Kim Elmore, N5OP __ 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] Another BC-610 Question
Ya know Todd, I'm looking for the same thing to replace the original AC connector on my Collins 30K-4. Those old hard rubber (Hubbel) connectors...sooner or later become brittle and crack and break. I need to find the chassis/panel mount version of the recessed 2-pin male twist lock connector that is rated at 20 A @ 115/120VAC. They seem to be rare or non-existent around here.

Pretty cool, to listen to the side-band power without the phase-shift and selective fading typical on an AM signal that rises and falls with QSB. What I DIDN'T mention was the mobile receiver that Otis built, when he came to San Antonio, in his 'Good-Times Van' (that he never had a good time in) to visit Koby/K5MZH(sk). It was/is a converter rig, that used 1400kc from the AM broadcast receiver in the van. Seems I recall, he built the thing up in 3 or 4 days, and then remembered "Oh, yeah - Koby's on SideBand, now" and as an after thought built up a product detector. He had 80, 40 and 10m in the little rig that was no bigger than a cigar box. John, was that the same project where Otis was on his knees with an Ohm meter, measuring resistors, looking for a 39k (I think)? (Otis is color blind, y'all) Poor Otis... had been checking a pile of resistors for a couple of hours, looking for the right Ohmage he needed with his Simpson, and John walked in the door, saw Otis on his knees and said "What -ARE- you doing?" Otis says "I'm looking for a (_fill_in_the_blank_) ohm resistor!" John took a diddle stick from his pocket protector and fished through the pile of resistors, and in about 45 seconds had about a half-dozen pushed over to one side. Otis said "Do you have any idea how long I've been down here on my knees checking each resistor? And then you come along and bam, there's 6 of 'em!" Ah, the good times! ;-) Wonder where that receiver is now, John? -- Driving your AM Rig without a scope, is like driving your car at night, without headlights.

Re: [AMRadio] Another BC-610 Question
Grainger, Home Depot if you go to the Contractors counter, Richardson Electronics on the web, or Mcmaster-Carr! That's where I got mine and spares, for my BC-610(E&I). As for how I connect it to AC I have a 30 Amp. line that runs to the operating position, where it is connected to a 0 - 130 VAC Variac @ 30 Amps, the output goes to the cable with the Hubble connector that connects to the transmitter. Query, did you check the wiring to your transformers, specifically the filament transformer for the 250TH? Adjustments to the front panel control (FIL) when set at 5 VAC on the meter ensure that the AC input to the other AC transformers is correct. It is advisable to check where they are strapped to as in some cases folks have changed the settings on one or more of the AC inputs for whatever reason. FWIW!

Re: [AMRadio] Receivers
Lots of receivers here also. A Collins R390A is the main AM receiver utilizing detector output to an external audio amplifier with a pair of 6L6s and a large speaker for nice audio. Also have a National NC 240D that really sounds great on AM with its matching speaker. A Collins 75A-1 and a 75A-2, Hallicrafters SX-28, a National NC-300, and a Hammarlund HQ-129X (doesn't everyone have one of those?) I also have in my collection (on the shelf) a National SW54 and an old Heathkit AR-3 just like the one I had back in 1959-60. The AR-3 has the relative sensitivity of a cardboard box, but was my first real communications receiver. It might be interesting, however, to note that my first "ham" receiver was an old Zenith 7S363 console that I pulled the chassis out of and set on the operating table. I utilized a another little ACDC radio along side the Zenith for BFO to copy CW by heterodyning the local oscillator in the Zenith IF.

"Modern" receivers include a couple of ICOM transceivers, but they just don't have the classic sound and ambience of the boatanchor stuff. 73, Jack, W9GT -- Original message -- From: [EMAIL PROTECTED] > > >what sort of receivers are in use in the AM community? > > __ 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] Receivers
Favorite receiving setup for AM is currently an R-390A. I-f output feeds a homebrew setup - 455 kHz preamplifier that drives a four way power divider...the four outputs are run into: 1) peak detector, 2) precision rectifier, 3) synchronous detector, 4) output to scope. The three audio outputs are selected by a Hafler DH110 audio preamplifier which drives headphones and a Hafler P3000 power amplifier / speakers. Also have (in order of next preference): SP600-JX17, Harris RF-590, 75A4, R75, etc. Jay W1VD > - Original Message - > From: "Kim Elmore" <[EMAIL PROTECTED]> > To: > Sent: Tuesday, September 18, 2007 9:27 PM > Subject: [AMRadio] Receivers > > > > Much of the traffic here concerns transmitters.

Re: [AMRadio] Receivers
There are two ways. Both involve muting/switching to standby the reciever: 1. Quick and dirty (and very old school) - switch the rciever to standby before transmittting by hand from the front panel. 2. For PTT-type operation - most halfway decent older receivers have a muting line on an accessory plug on the back of the receiver. Oftentimes you'll see a wire bridging the two muting contacts, so you can use the Standby switch on the front of the receiver. Wire the muting line contacts to a relay that's fired (and will go to Open when actuated) by the PTT/keying line of your transmitter. This will mute the receiver. Oh, I forgot to mention, some of the newer receivers will actually have a terminal labled "Receiver Mute" on them. The older tube receivers can take some abuse if you goof, and forget to mute them during transmit. But, it's not a good idea to do it all of the time, as the receiver can end up permanently desensed. 73, Ellen - AF9J - Original Message - From: "Jim Miller WB5OXQ in Waco" <[EMAIL PROTECTED]> To: "Discussion of AM Radio in the Amateur Service" Sent: Tuesday, September 18, 2007 10:38 PM Subject: Re: [AMRadio] Receivers > When using a receiver and a transceiver as a transmitter how do you switch > the antenna off of the stand alone receiver when transmitting.

The TS-2000 has an aux. jack on the back, right? There are some relay contacts in there for keying an amplifier, right? You could use those relay contacts control some voltage for a T/R relay, I'm sure. There's all kinds of ways of making that happen. -- Driving your AM Rig without a scope, is like driving your car at night, without headlights.

Re: [AMRadio] Receivers
National wrote a lot more service bulletins to fix a number of things in the NC-300. I believe there was only one for the NC-303. AM quality seemed to be the same on both receivers but the NC-303 definitely had far better stability for CW and SSB reception. Had two NC-300's and got rid of them but still have a NC-303.
