Re: [AMRadio] 144 Mhz. AM
It's 145.25 and the call is K1JCL. It's always fun to operate 2 meter AM
during some of the VHF contests. Drives the SSB guys crazy trying to tune
you in.

Hi Byron: 144.400 is still legal but you wont make any friends 10
KHz
down.
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
I think a good idea would be to try fair radio sales in OH. if you haven't allready found it when you read this msge here.They have a lot of military parts from various radios and i believe at reasonable prices.Think it's a good alternative solution to find out this inductor after that one of Harris.

Re: [AMRadio] 10 meter AM
Thank you to everyone who replied. I have a good place to start. Going to order crystals for 29.0 and 29.1 next week, then start the retuning after they are received. An old ham friend of mine in Georgia just gave me a RS HTX-10 mobile, which also has AM. I will try playing with that until the CB to 10m conversion is done.But tube rigs still sound better to me! BTW: Been seeing a lot of good DX on the FM end of the 10m band lately. I run converted commercial gear on 29 MHz FM, and run the 10m fm list on Yahoo http://groups.yahoo.com/group/AR29MHz-FM/ but have been wanting to play on 10m AM too. This will be a good start. I work professionally in the two-way radio business as a Master Technician at the factory in Lynchburg, VA, and know all too well how easy it is to get burned-out and not want to tinker with amateur radio as a hobby. (I was that way for years...) But I grew-up listing to stories recounted by my Elmer (Santiago, WA4KSD) of the 50's heyday of 10m 6m AM Phone. By mostly staying off the 2 440 repeater bands and doing something a tad different, the hobby is still fun. 73, Mark Cobbeldick, KB4CVN Monroe, VA __ Do you Yahoo!? Check out the new Yahoo!

RE: [AMRadio] 10 meter AM
The HTX-10 is a winner on AM. Audio sounds very nice even with the stock mic. I love mine. Current draw is low and works great with an amplifier, going from the 7 watt carrier to 70 watts with most good amplifiers. I worked Japan with that rig in the truck a few years ago! When 10 is open, 7 watts is at least 5-5 anywhere in the country.

Re: [AMRadio] 10 meter AM
Mark, The HTX10 will bring you lots of AM qsos too, but the tube rigs will indeed sound much better. I'm curious which cb model you will be converting.
[AMRadio] smelly oil in the Electro Manufacturing modulation transformer
Hello Group, I was organizing the storage area today. The last thing I moved was the mod transformer for the 5 KW gates parts unit. Well one of the insulators has a bad seal and it leaks oil from the transformer. Man! does it smell weird - like a thousand times worse than the old mimeograph machines did. I have to fix it or dump it. I think I'll fix it by sealing up the insulators. But what is that oil? tnx DE KA4JVY Mark __ Do you Yahoo!? Check out the new Yahoo! Front Page. www.yahoo.com
Re: [AMRadio] smelly oil in the Electro Manufacturing modulationtransformer
If it was made anytime prior to the early 1970's then it is Dektol, Pyronal or other trade names for PCBs. The bad stuff. Don't drink it!

Re: [AMRadio] 144 Mhz. AM
I was thinking JCL, but put in an R. Did he have a 6m AM repeater also? I
have been reading on-line about WA6TDD, one of the first 2m repeaters in So.
California. It started out on AM. Wish I could remember the guy in Little
Rock , AR that was on 145.35 with a kW on 2m AM back in the '70's. A friend
of mine worked him with an FT-221 from north AL. I wonder when the VHF
contests went from AM to SSB? Those FAA rigs seem like the best way to get
on 2m AM.

All this talk about 2m AM has me remembering that I have a Navy, VHF transmitter. Don't remember the nomenclature on it, but it was like a mini T-368, with three drawers; Top) Final (with (3) 3E29's in it) Middle) modulator, with p-p 807's Bottom) power supply. It's available, if anyone is curious enough to have it. I'd say a good 100w output. I'll be out of pocket for the next week. Plan a trip to South Texas to get it. 73 = Best Regards, -Geoff/W5OMR
