Put 60OFF in the promo window at checkout. Even though I have tube manuals, didn't have the Raytheon and ordered it from them. If you ever wanted info on flat hearing aid tubes, along with the rest of the Raytheon line, this is a good place to find it. The History of Radio Pioneers, 1945 is interesting too. I'm sure this is all online somewhere, but I'm old school, like my radios.

Most in the South know the nightmare that fires up, but how is it in the rest of the country? From the OT's of the 11 meter ham band days, they say 11 meters was wild and woolly and it all moved to 75 when 11 was taken away. Are there those 'special freqs' in your area where you might query QRZ several times, hear nothing, throw out a CQ and then get hammered with carriers, 4 letter words, and worse, telling you the freq was in use? Ever give out a short 3 X 2 CQ and get a raspberry for a response? Are there any civilized areas of the country on 75 in the evening? Do any of you operate regularly in the 3700 +/- range or just stay up on 3885? I've stepped on so many landmines, I usually stick to my local group a couple times a week.

Three nights ago, I tuned across 40m and heard nary a signal. It was so quiet, I thought the antenna had broke/fallen/came loose from the tuner... it was scarily quiet! I tuned from 7.290 all the way down until I got to 7.164, and heard a signal. Turned out to be ZS6CCY (google him - worth it!) just north of Johanasburg, South Africa. He was the only signal on the band, working North America. I moved off, tuned up quickly, and called and worked him. I didn't realize all the people calling, because I couldn't hear a -thing- stateside... then started hearing 1's and 2's, then 7's in the PNW... but that's about as close as it got. Right now, at 6:30pm, I'm listening to a Net where I know most all of the check-ins and where they are... I'm not hearing anyone in Texas or Louisiana (being in SE Texas). Only thing I'm hearing is a relay station near Portales, New Mexico, somewhere around 600 air-miles from here. I have no idea whats happening to the ionosphere. Did the F-layer go away all together? I listened on 7.160 AM as Paul/WA3VJB worked Darrell/WA5VGO for about a good 45 minutes. Kingwood, TX is only 10 miles from here and I could barely hear Darrell on his Collins KW-1. Paul's 300 was better, at my place, but not -that- strong. There was a point where he poked up to 20db/S-9, but that only lasted about half of a transmission. www.bandconditions.com 'kinda' shows what shape the bands are in, but generally speaking, not well enough (in my Not so humble opinion). Maybe someone who knows more and has kept up with the solar conditions, flux, A and K indicies could jump in and explain it better. 160m seems to be the way to go, but I don't have the room. 73 = Best Regards, -Geoff/W5OMR From k5xu at comcast.net Sun Dec 18 20:15:48 2016 From: k5xu at comcast.net (Mike Duke, K5XU) Date: Sun, 18 Dec 2016 20:15:48 -0500 Subject: [AMRadio] Very low MUF Message-ID: <903fd033.6e68.4183.b5a2.0d86e12ae650@samobile.net> It is not uncommon during much of December, especially in the days around the winter solstice, for the maximum usable frequency to dip very low after sunset, and remain low for much of the night. One evening last week, I could only hear WWV on 2.5 MHZ, and what I think was WWVH down in the noise on 5 MHZ. There were a few weak CW signals on the low end of 40 meters, but everything above about 7.150 was empty. The winter solstice occurs this Wednesday, Dec. 21, so look out for lower frequency propagation tricks especially this week. -- Mike Duke, K5XU From k5xu at comcast.net Sun Dec 18 20:33:15 2016 From: k5xu at comcast.net (Mike Duke, K5XU) Date: Sun, 18 Dec 2016 20:33:15 -0500 Subject: [AMRadio] Winter Solstice AM Broadcast Propagation recollections Message-ID: The only two times I ever heard KFI (640 KHZ in Los Angeles) from my Mississippi QTH occurred within the last two weeks of December. I don't remember the exact date, but the last time I heard them was at least 30 years ago. Similarly, as a kid who was convinced that WLS was the absolute ultimate in rock 'n roll radio, one of my goals was to hear them at noon. I did it twice. Both times were on or within 2 or 3 days of Dec. 21. Again, this was from my Mississippi QTH which was about 200 miles southeast of Memphis, TN. That will never happen again for reasons that we all know too well. During those much more quiet listening environment days, I would also often hear WLW, KMOX, and other signals that were normally heard only at night, as late as 10 AM or so this time of the year.

It's like this radio season never really took off. Weekend evenings, low QRN and 75 and 160 still have wide open swathes of unoccupied frequencies. Not just AM; no SSB, no CW either. Just a few years ago on a similar winter night you would have to hunt for a clear spot to call CQ. They roll up the sidewalks on 160 after about 9 PM. Even with propagation wide open I sometimes call CQ till I'm blue in the face and no response. You have to get a QSO well established before 8:30 or 9 to hope for any late evening operation. Where are all those 700,000-plus hams that reportedly make up the largest FCC data base in the history of radio? They are certainly not active on the radio. Is this the new normal?

That's why I became acquainted with the station. It has always been very difficult to hear classical music in the radio in my country, although in my 1.000.000 city we have regularly 5 classical live performances per week.

James Weldon the founder of Continental designed and built the rig. When Collins Radio was selling off its broadcast division Continental bought the designs and assets and continued building some of the gear and mixed in their own designs. All of the FM transmitters at the stations I work for are Continental and they're great rigs, we even have a Rockwell "rocket ship" version of the 831G as a back up, but I'm afraid that Continental is well on its way down the drain. We had several Collins AM transmitters but they'e been replaced by newer designs (one of which has a high coefficient of suck). I know that Jim Tonne worked for Collins along with other engineering greats like Jack Sellmeyer but the company that exists today is a shell of its former self.

The General Class ranks increased by 61.8K during the same time frame. The Tech Class ranks only increased by 33.4K during the same time frame. So, licensees with lots of HF privileges, increased by 129.8K during the same time frame. I doubt "no-coders" have anything to do with less perceived activity. 50 years ago there were generally 3 main modes, CW, AM, and SSB. Today, the list of available modes is a mile long. Over the last 15 years, numerous digital modes have gained in popularity along with some obscure modes gaining interest. Plus, there is probably a large subset of licensees whose main interest is contesting and DX chasing and have little interest in day-to-day idle chit-chat in any mode. Today there are other amateur related on-the-air activities that might be time/day/week defined that further reduces the number of idle chit-chat QSO's. Amateur radio activities are a lot more varied today then they were back in the "good of days". As we move forward in the 21st century, I find it easier and less unsettling not to look back as to how it was in the past since it's difficult to repeat the past and the players are always changing.

But before the Color Radar, back when WLS switched from The Barn Dance station to rock and roll in 1960, they bought a memorable set of jingles sung by the Anita Kerr Singers, including the famous "Radar Weather Eye" which can be heard at 1:25: https://www.youtube.com/watch?v=MLu4UVorDSo The jingle featured a long instrumental bed for the announcer to describe the weather including what was forecast using the newfangled radar gizmo. I think this set the stage for how radio stations tried to incorporate visual elements into programming and probably triggered the idea that visionary program director Chuck Blore exploited a year later to create the "Color Radio" format for a chain of radio stations across the US. Color Radio and channel numbers became the metaphor for moving his stations into the forefront of their markets, just as color television was doing in the visual media. The most recognizable Color Radio station was Los Angeles's "KFWB Channel 98". You can hear the Johnny Mann Singers jingles and read all about Color Radio at http://www.colorradio.com But the most interesting part of this story to me was discovering that in this case "art" imitated "life". As explained at the link below, noted LA film score composer heard the six note KFWB musical signature at the end of the Johnny Mann jingles and approached the station about making a full-length instrumental record based on it. The result is called "Image" (parts 1 and 2) and is a nice jazzy tune that actually hit #1 in Los Angeles! http://bayarearadio.org/audio/kewb/kewb_theme-song_1961.shtml I'm a bit nuts for this kind of radio history so thanks for indulging me.

Back in 1952 I was a Boy Scout and got Boys Life Magazine. The magazine got me interested in ham radio and they had an article in it on how to build a 6V6 Slat board Transmitter. But I never heard a ham signal. I had gotten a Burstein Applebee catalog and in it they described this Loop Stick Antenna. The way they described it, you could remove the loop antenna from an All American Five radio and install this thing. With it, it sounded like I would be able to pick in every AM station in the US. So I paid my Dad to order this 35 cent device. It arrived just about the time I stayed home one day with a cold. I was in bed and had nothing better to do and I was getting board listening to local AM station with my mother's kitchen radio sitting next to me on my bed. (I was listening to local 250 watt station, WEMP, Milwaukee). So I decided to install the Loop Stick Antenna and see what it did for the radio's sensitivity. (As most of you know the Loop Stick Antenna was nothing more then an input coil tuned to the broadcast band. This one had an adjustable slug in the coil.) So I got it installed and now I turned on the radio and had to adjust the coil slug for "best signal sensitivity." It did indeed peak to the frequency in use but the signals didn't seem any louder using it. But what amazed me was when I basically removed the slug from the antenna coil I was hearing AM Ham stations! I later found out I was listening to the 75 meter ham phone band. I was hearing a whole bunch of hams talking in and around the Milwaukee area. I was amazed at all this and from that time on this radio was basically a 75 meter AM radio and no longer a BC set. I listened and listened and got to know these people a good year before I became a general class ham myself in early 1954 as W9DRC using my new Globe Scout 40A transmitter and Hallicrafters S-38C receiver. (I got to know by listening, w9hif, w9pym, w9ezz, w9mer, w9zaz, w9ttt, w9uit, and many others with this lowly Motorola All American Five receiver.)

I was amazed at all this and > from that time on this > radio was basically a 75 meter AM radio and no longer a BC set The same thing happened to me. I had been listening to 40m and 20m phone on our BC receiver with one 6-18 mc short wave band. I had never monitored 75m because I didn't have a receiver to cover it. I found an old 5-tube AC/DC set in a dumpster, brought it home and tinkered with it till I got it running. The back masonite cover and loop antenna attached to it were missing, so I strung up a wire antenna and attached it to one of the wires that originally connected to the loop. Lacking the front-end selectivity provided by the loop, images came through about as well as the fundamental signal. Starting about 4 PM on winter evenings, 75m phone signals began to override anything on the broadcast band. Evidently, over a certain portion of the AMBC band, the second harmonic of the local oscillator would beat with the 75m signal to produce the i.f. signal. I was introduced to the 75m band using that receiver, and a year or so later, picked a 1939 vintage all-wave floor model broadcast radio that had both longwave and shortwave bands, and a RF stage to boot, and had a real shortwave receiver. I later added a BFO to the all-wave set and used it while I was a Novice. At the time, 75m was almost 100% AM, and a whole lot different from what it is now.

Before IL, the Extra Class was something hams could earn for pride of accomplishment but which carried no additional operating privileges beyond those of the General. When it became necessary to have the Extra for full amateur privileges, that changed the whole nature of the licence class. It was no longer a mere trophy to display on the wall for bragging rights. When the 20 wpm was dropped (and eventually the code test altogether), and Advanced class privileges discontinued as an option for upgrade, the option is now either the General class with highly restricted privileges or the Extra for full amateur privileges, so Extra Class is no longer anything special. This is especially true with current system of published, verbatim, questions/answers for the M-C written tests. A better nomenclature for the three present-day licence classes would be Full, Limited (or maybe Restricted), and Communicator. The name "Technician" is a joke.

The words "home brew" were reserved for building gear such as transmitters, receivers, antenna tuners, amplifiers, etc. Building a dipole from a roll of wire, a few insulators and roll of feed line was a given. You never said you "Home Brewed" your wire antenna.

The "class D" (PDM, PWM) tube-type broadcast transmitters employ a class D *modulator* operating at, I believe, the 60 - 100 KHz range. The RFPA in these transmitters is conventional class C. My homebrew "big rig" also uses a class D modulator (an 833A) at about 80 KHz, but the RFPA is just a tube-type class C final with the negative lead floating, because the modulator is in series with the final from a DC and AF perspective. Because its a series modulation scheme, the DC supply needs to provide more than double the quiescent voltage required for the RFPA, but there is almost no extra energy wasted in the modulator. The HV supply needs to provide more voltage, but much less current, that a power supply that supplies both the RFPA and a "conventional" analog modulator (for example, class AB1, AB2, or Class B). If a tube-type class D modulator can operate at 80 KHz, which it can, it is not a big stretch to expect it to be able to operate at 137 KHz in an RFPA. But this is the pulse repetition frequency, so there is significant odd harmonic content, and therefore significant energy that must be amplified, at much higher frequencies. I have much less experience with/knowledge about class E amplifiers, so I cannot say much about that part of the question. 73, -Larry/NE1S From ranchorobbo at gmail.com Tue Dec 27 09:31:55 2016 From: ranchorobbo at gmail.com (Rob Atkinson) Date: Tue, 27 Dec 2016 08:31:55 -0600 Subject: [AMRadio] Can you have Class D and Class E tube amps?

The Retro75 and Retro40 transceivers made by Small Wonder labs used a class D RF output stage using a power FET followed by a LPF. Both class D and E can use sine wave drive, or preferably a single polarity pulse that is about 40-45% the width of a half cycle. The output circuit for class D is a LPF, and for class E, it is a resonant tank. Class E is usually a little more efficient, but class D is simpler in that no tuning is required. For 137Khz, if the old 1 watt DC input rule is still in effect, you want the highest efficiency possible. Therefore class E would be desired. Should be able to get 95% or higher efficiency.

Hi Chris. I have investigated both D and E designs based on FET, MOSFET, HEMT devices and there is nothing sacred about the designs which forces them to be linked to solid state units. The success of these designs is based on the ability to provide properly shaped current and voltage waveforms across the device and at the load. As one figure of merit, the FT or FMAX of the device applied to FETs can be applied to tubes and in a similar manner compute a gain/frequency figure of merit. Bottom line high gain at high frequency compared to the operating frequency is a place to start. So a tube with significant gain at 136 MHz would be a good start.
