RE: [AMRadio] Collecting vs. Hoarding (was: Value of Homebrew RIgs)
Todd wrote: I tend to avoid anything that involves telling someone what they can or can't have, or that they should redistribute their wealth. I agree absolutely. I would never support prohibition against collecting -- even when it mutates into hoarding -- nor would I support any sort of forced redistribution of anyone's wealth. But, I certainly claim the right to question the motives or even the sanity of someone who behaves as I described in my previous post (the lighthearted nature of which I hope showed through without the need for smiley faces). If a guy wants to fill his house up with Pez dispensers, or baseball caps, or whatever, that's his business. When does collecting become hoarding? It a guys wants a pristine example of every piece of gear that Collins ever made, and sets out to acquire them, that is great. More power to him. On the other hand, if a guy set out to purchase every piece of Collins gear he can find, which then disappear into his basement never to be seen or heard again (until he croaks, as a John pointed out), I don't think that is fine. I think it is indicative of mental health issues, and it is harmful to the hobby within a hobby of collecting old ham rigs as it keeps other folks from being able to participate. There is an unlimited supply of Pez dispensers, but there is a very limited supply of old radios. If there weren't, then a 75A4 would still sit all day in the hot sun at a hamfest with a yellow sticky on it that says '$100 OBO'. Just my opinion - if you feel I have stepped on anyone's toes, that's ok. I probably did. If you have ten John Valiants in your basement I think you should sell some of them.

When I was a 13 yesr old novice (WN4YEJ)I went to work after school in a TV shop fixing ac/dc radios and helping carry TVs on service calls. There was a business radio there we used to talk to the service vans. It was right next to the workbench where I was happily changing out 50C5's and 35W4's all afternoon. One day it was making strange noises, like waves breaking on a beach. Then I heard someone say ... in Arizona. I picked up the mic and said This is Georgia, and he replied I hear that Georgia station . I freaked out and quickly went back to work. For the next week I expected to get to work after school and see an FCC monitoring truck waiting for me! It wasn't until much later when I saw another White Faced Johnson that I realized it has been a CB station that I had worked Arizona on all those years before. Theo K4MO

[AMRadio] 10 Meter AM Frequencies
I seem to remember that about 20 years ago some folks were converting 23 channel CB rigs to use on 10 meters (by legal hams, of course). I think they were just changing four of the xtals in the xtal synth circuit and ending up with 23 channels in the 10 meter band. At the time I think there was some sort of agreed upon scheme so everyone was ending up on the same 23 frequencies. Does anyone know what these are? If not, what would be a good choice of frequencies for such a conversion? I have an old antique tube type CB rig I want to put on 10 meters. Thanks 73, Theo K4MO
[AMRadio] Homebrew Receivers (was: receiver tests for Theo)
Brett, I sure would like to see some pics of your homebrew receiver, and hear some more about it's design (tube lineup, if strip, audio section, etc). I have never built a receiver. Lots of amps, some cw transmitters, and lots of accessories and surplus mods, but no receivers. Did you design it yourself, or did you pattern it after a published design (like the famous HBR series)? My requirements are for AM only on 160, 80, and 40, with attractive classic appearance and controls that are pleasing to use. This is for a station that will be installed in the den so it can't be an ugly mess o' wires n' boxes.

The receiver filter is 5.5Kc since my ears don't work well at high frequencies, so the recording is limited... I have never taken an analog tape and converted it to a digital format. I would wonder how good a typical sound card would work converting analog to digital. On the subject of picking a receiver, I got tired of the limitations or flaws of all the commercial stuff, it seems every receiver is a compromise between cost and function, some had great audio but you had no idea of the frequency you were on. Others did SSB very well, and AM lousy. Some did AM well, and ssb poorly. Some looked very cool, some were very ugly. Some drifted, some were stable. Some were very quiet (old stuff) some were very noisy (new stuff). Some had good bandwidth choices, others had poor or no choices. Some make no provision for TX muting. If you don't want to band hop, the r390 series works very well on AM, although it needs outboard audio and is on the noisy side. My homebrew receivers were built to function, I want low noise, low distortion, accurate frequency readout, 160, 80 and 40 meter coverage, a xtal BFO for zero beating AM signals, a scope output, an S meter, and good AM selectivity choices. As an added benefit, I made it look like the rest of the home brew stuff, and made it so when you switch bands it goes from 1880, to 3880, to 7290 when you change bands. They SEEM to work well, but I need someone with good hearing to really nit pick them. Eventually, I want to add many bandwidth choices, 4, 5, 6, and 8Khz maybe. Other than the homebrews, I only have the G76 and an Icom 756 pro. The G76 has audio amp limitations, the 756 is very noisy, and rolls off the low end even with outboard audio. There are many times I could not copy signals on the R390a or the 756 that were good copy on the homebrews, weak signals on quiet bands is where the homebrews really shine. I would think an NC300 or 303 with outboard audio might be reasonable and sound good. The R390 series has a scope output built in, and it works well on receive and transmit. Its got muting, its accurate, but it is expensive and trouble prone.. Just my two cents...

RE: [AMRadio] 51J3 or 75A3?
Wow! Thanks for all the great insights. It has me rethinking the entire idea of putting together a classic AM station for late night Hi-Fi Radio. My original idea was to recreate the feel of the station in which I took my Novice test back in '64. It was a 75A4 and a Globe King 500B. But that notion has since taken a turn to be more focused on audio quality than nostalgia (while still using classic rigs), hence my original question. Seems I have lots to learn yet before I decide what to do. The suggestion that I go visit some collectors and listen to a number of different receivers is a good one. Any volunteers within a couple hundred mile radius of Charlotte, NC? Thanks again all! Theo K4MO

I have had lots of vintage receivers in the past (especially Collins), but I usually used them on CW or SSB. The last old gear station I had was a Johnson Valiant and a 75A4. I thought the 75A4 was doing ok (it has an R390A AM filter cobbled into it) until I got a 51J4 which seemed much better on AM. So, I thought for this set up I would spend a little more time learning from the guys who have been more dedicated to 'Angel Music' that I have been. I usually just end up with whatever rig catches my eye at a flea market or whatever. I am hoping to take a different approach this time.

RE: [AMRadio] receiver tests for Theo
Paul, Thanks! Very cool ... I will listen to them again tonight on the ham shack computer where I can play them back through some good speakers without the distractions that abound here in the office. I hate it when trivial work concerns interfere with my important hobby activities.

This past weekend Brett N2DTS and myself were in QSO on 40m with a fellow running a very clean sounding DX-100. We both rolled tape on a specific part of the guy's transmission. Brett if you still have that sound file, maybe render it down to an MP3 and I'll do the same? We can then describe receivers. Meantime, there are some other sound files kicking around that are worth downloading. I've got a few that I remember what receiver I used: From the diode of an SP600 at 13Kc selectivity: http://www.wa3vjb.com/sound/HUZ-FT102%20(2).mp3 From the diode of an R390 at 16kc selectivity: http://www.wa3vjb.com/sound/W2DTC-doodler.mp3 From the line output of an R390A at 8Kc: http://www.wa3vjb.com/sound/W0VMC.mp3 Steve, WB3HUZ has a pile o' files too: http://www.amwindow.org/audio/htm/audio.htm Here is the sound of a 51S-1F up on 10 meters AM: http://www.amwindow.org/audio/mov/f5hsh.mov In addition, check this batch of wav and MP3: http://www.amfone.net/audio/ These will give a continuum of sound quality for sure.

[AMRadio] 51J3 or 75A3?
I am shopping for a receiver to use on AM. I think I want either a 75A3 or a 51J3. Which one is best for AM use as far as making pleasing sounds come out of the speaker? I used to have a 51J4 and a 75A4, and they worked fine (especially the 'J4), but I have heard that the 'J3 may have the best sounding audio section for AM. True? Thanks, Theo K4MO
RE: [AMRadio] wireless cross-technology
Good thing you have an extra one, Bob. Seems everyone is out of stock on the 900 mHz headset/mics. All they have now are Blue Tooth versions which are much shorter range ... :-( If anyone knows of a source for one (Logitech 980118 Cordless Freedom Headset or similar non-Blue Tooth model) I sure would like to know about it.

Not a big estate HI!!! I can listen and transmit using VOX from anywhere. One line to the headphone jack and one to the mike jack. Works full duplex... About $35 anywhere on Internet. It is called the Logitech Cordless Freedom Headset. It has 20 scanning channels, Base station with rechargeable Batteries, Don't know the cost today as I purchased mine a good 5 years ago and have an extra one still in the box. It says up to 1000 feet but have gone further... Bob W1PE
[AMRadio] Looking for a restoration project
Hello I am looking for a restoration project. Something between a Valiant and a KW-1 (quite a range, huh?). I want to do a down to bare chassis strip and rebuild. The ideal candidate would be a Globe King 500 or Johnson 500 but I would be interested in other suggestions. Do you have a rusted hulk languishing in the corner of your basement, crying out to once again make RF? Thanks 73, Theo K4MO www.qsl.net/k4mo
