Jim,
If you want to fire up ur rig and call CQ on 7160 when there is a qso
on 7161, 7158 or 7162 be my guest, it is your station not mine, but
where I come from, we call people who do that lids.

Rob, I don't think that is what Jim is suggesting at all. Rather, he is
likely referring to the 'dead air' groups who leave a radio running to
listen for their buddies, but aren't in QSO. You can listen to the frequency
for long periods with no activity. But call CQ or ask if the frequency is in
You are correct Todd, that is precisely what I meant. There are several
groups like this scattered around mostly in the lower part of the phone
segment. I have had run ins with them not only on AM but SSB. Rod,
amateur radio is not an intercom now does anyone own a frequency as Todd
says.
Just as a side note - a tip of the hat to the oft-time phenomenal
band conditions that can exist on 40m in the DAYTIME hours
for a good AM contact
I have known 40m to produce some great S9+2-dB signals from
simple 30-40 watt AM transmitters over rather short distances - say
out to around
You're right - and for heavens' sakes if you say Is this frequency in use?
They will come backl and say yes, and start talking with each other for
a few minutes then back to their standby mode.
In traffic terms these are called road hogs - the guy who drives at
20 mph under the speed limit in
To a certain extent, the same thing has happened on 40m since (most of) the
BC stations went away, as happened on 75 when the band was expanded down to
3600. Back in the spring, there was a lot of activity on 7160 at first,
until the novelty wore off, and gradually the activity has dwindled.
Hi Jerry... I have 2 heil PR-40 mics that I use on
Am... These have tremendous low end. I have a
GATES BC1G Broadcast xmtr that off course can take
the low end... I use a Radio Design labs mixer
with their parametric EQ and a URIE Limiter.
Everyone one says it sounds as good as some of the
best AM
How about against the RE27, your opinion?

Bob, As you have pointed out about other microphones, the Shure 55
Series has a VERY long and distinguished history of use under all
conditions on stage.
They get waved around, swung and banged on. They still keep ticking!
Best with 5Meg ohm input, but will also do well as low as 1 Meg Ohm.
I own several Shure 55S and E-V 664 and have used both quite successfully
(in Hi-Z) on my BA transmitters: Apache, DX-100, and the Ranger.
You have to modify the mic input circuits by raising the grid-leak
resistor to at least 5 megohms or more, and change out the coupling caps.

The most important single accessory item to have in your AM shack is a
way to monitor modulation - a cheap o'scope is a good choice. Keep an
eye on it to ensure you have reasonably strong average modulation
levels, and negative peaks that don't go all the way to 100% and pinch
off the carrier.

The D-104 or any other crystal mic needs to work into PLENTY of megohms of
load resistance. Astatic recommends 5 megohms, but I run mine at 10 megs -
probably about as high a grid leak resistance that you can use in a tube
type preamp and maintain stable operation. I have plans in the works
pair of high-mu triodes in a push-pull mic preamp. That way, each tube
can
have its own 10 meg grid leak to allow for a 20 megohm load on the xtal.
It's possible to duplicate a similar circuit using an FET differential
amplifier with dual FETs in a single package (e.g., 2SJ109), or a

If any of you guy want it I have a schematic for a Mic Pre using a SSM 2019 Mic

from Mouser or Digikey.
