[AMRadio] 10 meter AM
I am active on 10 meters (FM SSB) for some time, but have never played with AM on this band. Recently a ex-CB (no-code) Tech neighbor gave me several functional older tube-type crystal controlled CB radios, which I am considering converting some over to 10 Meters for AM. Being crystal controlled, what frequency(s) should I have rocks for? IE: Calling frequency Thank you in advance... 73, Mark Cobbeldick, KB4CVN Monroe, VA __ Do you Yahoo!? Check out the new Yahoo!

anything between 29.0 and 29.1 would work great!

Re: [AMRadio] 10 meter AM
There is no defined calling frequency. This is non channelized AM radio. Find a clear frequency between 29.0 and 29.1 and call CQ.

Pete, wa2cwa That's true, Pete, but, please, let me post here my personal opinion, after more than 10 years of AM activity : the best calling frequency when the band is apparently dead is 29.000 MHz : here many people leave the radio switched on and tuned (when doing some other job in the shack...hi...).

Re: [AMRadio] 10 meter AM
Mark, Don't let the low power of the cb rigs discourage you. Get one going on 29.0 or above up to 29.1, and keep trying for contacts. I have had 2 different converted rigs, one old Radio Shack 23 channel ssb/am unit in the late 70s with which I worked almost all states and many countries with a dipole. The other is an 40 channel am only Sharp unit from about 1980. I still have it, and it works very well. It tunes from 28.965 - 29.405, using the standard cb channel spacing. Someday I will get ambitious and add at least one extra crystal so that I can park it on 29.0 for monitoring purposes. I also have an old Viking Messenger, but it needs lots of work. Unfortunately, it was the cb model, not the original one for 10 meters. Mike, K5XU
[AMRadio] One-of-a-kind Broadcast Transmitter available.
I am only the messenger, in case someone is interested. Do not call me. Contact Theo, N8CSU @ (865) 925 1290. Pair of 805's modulated by another pair of 805's, 250 watts. Built circa 1945. Custom-built by a company called ERI; supposedly only three were ever made and the other two ended up in a landfill. Transformer coupled with UTC LS-series except for Thordarson mod xfmr. He says the transformers are oversized and the transmitter could run greater power by replacing the 805's with larger tubes such as 810's or 450TH's. Cabinet is 78 high and 31 1/2 wide and righ weighs over 1000 lbs. Located near Knoxville, TN.
Re: [AMRadio] 144 Mhz. AM
Hi Brian: Well,the ARRL and others virtually took over 144.390 for a digital
vehicle tracking system so you can follow suitably equipped mobils around and
know where they are at all times the radio is on. There are other uses for the
system but in my opinion, the above is all they really do. There is activity
24/7 on that frequency, even in Florida (HI) I bet. BTW, I dont want anyone
knowing where I am at all the time. There are some good points though, if some
idiot steals your car, you might be able to find it.

Hi Byron: 144.400 is still legal but you wont make any friends 10 KHz

Their FM receivers are lots wider than our AM receivers, in general.
I have ground some crystals for 144.320 and 144.360 MHz ( one calling and
one working freq.) Remember though, most AM receivers are tunable so you
can
work cross frequency if you can get their attention. I too have a TV-7
FAA Tx (had 2 and gave one to a friend).
I have worked Texas many times before on CW and SSB, especially in the
summer but we usually have a few openings in January or Feb. Let me know
if
you hear anything or would like a schedule. Good luck on AM.

Hello-
I am getting my 2 meter antenna system back up and running. One thing
I
have played around with is surplus FAA AM gear that can be operated on
144.400 Mhz. Although I made only pre-arranged contacts in the past I
was
curious if there are any reports of 144 Mhz. activity in the Houston,
TX.
area ?
I have crystalled up several different pieces of equipment on the AM
calling freq. of 144.400 Mhz. I have heard that this calling freq. cannot
be
used in some area due to interference from other modes. I guess I will
find
out soon but I thought I would ask.
Right now I am working on a surplus FAA airband transceiver, it is
solid
state and crystal controlled, but appears will do nicely for 144 AM. Hate
to
invest in crystals I can't use! This unit is the TRX-102, a 1972 era
design
that has a good sensitive receiver and about 5-7 watts out.If others are
interested I have written down the conversion info.
I do have a few nice tube-type 50 watt plate modulated AM
transmitters
that cover 144 Mhz easily, these are the TV-6. They have a 4X150 final
modulated by a pair of 6146's. These units are beautifully built with
all
sealed transformers, about 3' tall rackmount, about 130 lbs. I have one
set
up on 144.400 that easily puts out 50 watts of nice sounding AM. I
believe I
have 2 or 3 checked out and wrapped up in protective coverings in my
shop.Have a full manual for it too.Have an extra tube-type receiver
{RV-12}
that does fairly well when crystalled and tuned on 144 Mhz.
Anyway, I would like to find some AM friends for 144 Mhz, my antenna
system will be high performance { pair of 18 ele. yagis at 100'} so will
have
250 mile plus range.

Re: [AMRadio] harris Roller Inductor
Hi Tony, nice to talk to you today, I told Jane you enjoyed the wine, she said she has a bottle in the ref., too bad your not here to have a glass with her since I don't drink wine. If you can't find the Harris inductor, you may want to consider using only half of the tuner, i.e. one inductor/cap and FLOAT the tuner with the one leg of the feedline going to the normal output terminal and the other leg to chassis ground. You have to use a 1:1 balum on the INPUT. I have done this with 3 unbalance tuners with good results. Of course, the true balanced tuner is still the best way to go. I prefer the linked coupled type vs. the dual inductors type since common mode BC signal can be a problem if your are near high power AM BC stations. 73's Butch From [EMAIL PROTECTED] Wed Nov 3 19:57:14 2004 Return-Path: [EMAIL PROTECTED] Delivered-To: amradio@mailman.qth.net Received: from mail2.brightok.net (mail2.brightok.net [69.8.2.137]) by mailman.qth.net (Postfix) with ESMTP id 87054859C5E for amradio@mailman.qth.net; Wed, 3 Nov 2004 19:57:10 -0500 (EST) Received: from Wilhite ([69.8.16.8]) by mail2.brightok.net (8.12.10/8.12.10) with SMTP id iA40sD6l91 for amradio@mailman.qth.net; Wed, 3 Nov 2004 18:54:16 -0600 (CST) Message-ID: [EMAIL PROTECTED] From: Jim Wilhite [EMAIL PROTECTED] To: Discussion of AM Radio amradio@mailman.qth.net References: [EMAIL PROTECTED] [EMAIL PROTECTED] Subject: Re: [AMRadio] 10 meter AM Date: Wed, 3 Nov 2004 18:54:15 -0600 MIME-Version: 1.0 Content-Type: text/plain; format=flowed; charset=iso-8859-1; reply-type=original Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 6.00.2900.2180 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2900.2180 X-BeenThere: amradio@mailman.qth.net X-Mailman-Version: 2.1.4 Precedence: list Reply-To: Discussion of AM Radio amradio@mailman.qth.net List-Id: Discussion of AM Radio amradio.mailman.qth.net List-Unsubscribe: http://mailman.qth.net/mailman/listinfo/amradio, mailto:[EMAIL PROTECTED] List-Archive: http://mailman.qth.net/mailman/private/amradio List-Post: mailto:amradio@mailman.qth.net List-Help: mailto:[EMAIL PROTECTED] List-Subscribe: http://mailman.qth.net/mailman/listinfo/amradio, mailto:[EMAIL PROTECTED] X-List-Received-Date: Thu, 04 Nov 2004 00:57:14 - No one has really mentioned 29.1 to 29.2.

Re: [AMRadio] 10 meter AM
Jim and others, I too have made a few contacts above 29.1 and below 29.0 near the peak of good conditions. I haven't made any am contacts near 28.8 since the early 70s. I still have my old crystal that I ran for 28.825 with my original Viking Ranger when I was in high school. These days, unless there's a contest or unless conditions are really great, you won't find much ssb above 28.6, and even less above 28.7. I bet it won't take one weekend of operating much below 29.0 for some ssb cop to start screaming about us being illegal because we're out of our band plan! Let'um holler! If I find any AM on 10 meters, I'll answer it.
