[AMRadio] 10 Meter AM Open
Beginning just after 11:30 AM central time, I had a 15 minute qso with Bob, K0RDF in Mo. I had to bale out when the phone rang. Haven't heard any other AM on 10, and none on 15. He was running a great sounding Ranger, and I was on my usual Kenwood TS570.

Re: [AMRadio] OT but of interest to some
Now living in Utah, obviously I can't listen to WLS directly - at least during daylight hours. Nice to listen to the internet stream. I lived in Chicago for a time 20 or so years ago, and fondly remember them as the "Big 89." A major interest in my hobby is restoring vintage broadcast receivers, and also building high-performance crystal sets. I have one local AM station in Provo that broadcasts music. Otherwise, it's band edge to band edge of conservative talk and sports. I've set up my own Part 15 transmitter so I can at least have something worthwhile to listen to on my old radios if the Provo station doesn't suit me. Now, KSL in Salt Lake, for example, has gone digital. They still broadcast analog as well, but the digital content spews 30KHz wide! Why does Rush, Sean, et al need "digital" AM? The market might be small, but I believe there is still a market for music on AM. 73, Joe, N6DGY Pleasant Grove, Utah On 5/28/07 8:20 AM, "Robert Nickels" <[EMAIL PROTECTED]> wrote: > The "Big 89 Rewind" aka WLS MusicRadio is back the air today - listen > live at www.wlsam.com if you're not within the sound of Lyle Dean's > voice.

Re: [AMRadio] OT but of interest to some
Here in Oklahoma I have a choice of music, if you can believe it. There is an old country station down near Dallas, TX that plays it plus a small town station about 50 miles away. On top of that a station about 25 miles South has R&R from the late 60s to the 80s. There is another station about 25 miles North that has the same format, unfortunately it subscribes to the same satellite service. In Dallas there is also a big band station KAAM which gets some of my attention. Frequencies for all this is 770, 1190, 1240 and 1470. That keeps my dial lubricated. But I do miss 50 KW KOMA in OKC playing true R&R from the 50s to the 80s. They sold 1520 a couple of years back and now it is talk. The R&R format moved to the FM band with 4 of the old time DJs from the OKC market. As a youth I had it good in SW Oklahoma. 890-WLS, 930-WKY, 1510-KSTP, 1520-KOMA, 1060-WNOE (remember Jack the Cat?), 1200-WOAI, 940-KIXZ, and 990-(I forget their call) in Wichita Falls, TX.

KNIN is the station I could not recall. It was 990 and there was another station there owned by Raymond Ruff that was its competitor. I don't remember what the frequency or call of the other even though I worked for KIXZ in Amarillo from 1968 until 1972, also owned by Ruff.

[AMRadio] Better AM audio for a EF Johnson Messenger2
Hey all, Has anyone here ever played with a Johnson Messenger (or Messenger Two) CB on 10 meters? I am looking for suggestions on how to get better sounding audio out of the one I have. The Hardwired Crystal "Banana" microphone is coming off ASAP and I plan on inputting audio from my rack gear, or using a more modern dynamic microphone. But I know this thing has to have some audio bandwidth bottlenecks. Has anyone ever used one on the air? The schematic is here: http://www.cbtricks.com/radios/ef_johnson/messenger_2/graphics/messenger_2_s ch.jpg For Starters, I think C24 needs to be increased to .22uf, to let some low end through.

Re: [AMRadio] Better AM audio for a EF Johnson Messenger2
I remember being amazed as a 10 year-old when a family CB friend changed from the stock Johnson hand mic to a non-amplified Turner desk mic on his Messenger 2. The fidelity improvement was incredible. So, install your favorite mic connector. Then, follow your ears and your instincts. If you want to keep the physical appearance unaltered, just put the connector on a pig tail. I have two Messenger 1 units awaiting restoration myself. At least one of them will end up on 10 meters. The other is so dirty that it may end up as the poster child for a cleaning product.

Re: [AMRadio] B&W 850-A vs 852 Pi-Network assembly
Larry - The 850A and 852 have the same voltage rating but the plate impedance for the 850A is 2500 to 5000 ohms, while the 852 is 1500 to 3000 ohms. In other words the inductance of the 850A is 13.6,6.5,1.75, 1 and 0.8 microhenries, and the 852 is 7, 3.72, 2.34, 1.34, and 0.95 microhenries. I have a chart that shows capacity to resonate on each band, etc. from an old B&W catalogue if it would help. It's sure not a drop in, but I expect you could make it work ok except perhaps on 80 with a bit of juggling.

While I know that the B&W butterfly cap is worlds different from the pi-net tuning unit, it should be noted that the wider the impedance rage, the easier it's going to be to match it with a 'normal' sized capacitor. The capacitance on the tuning cap in my push-pull, link coupled final isn't -quite- enough for 75m. A split-stator capacitor was added in parallel to allow the tank circuit to resonate on 75m. I understand if you think the 850-A is what you've designed the rig around, but from what I see about the 852, it's range is more dynamic.

RE: [AMRadio] Better AM audio for a EF Johnson Messenger2
Bow, I would change out the following capacitors to .1 uF (or .22 if you like; there won't be much diffeence): C24, C31 and C35. C24 is key, while C's 31 and 35 will also affect receive audio (more lows). While your at it, remove resistor R48, or make it much smaller. It controls power output. Finally, you can either leave R22 as is, or change it out for a 10 megohms. 10 megohms is required when using an un-amplified D104. Otherwise, that 4.7 megohms is satisfactory for most Hi-Z mics. -- Bow wrote: Has anyone here ever played with a Johnson Messenger (or Messenger Two) CB on 10 meters? I am looking for suggestions on how to get better sounding audio out of the one I have. The Hardwired Crystal "Banana" microphone is coming off ASAP and I plan on inputting audio from my rack gear, or using a more modern dynamic microphone. __ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net 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.
