Subject: AM Sensitivity Problem with TM-241A ??
To: info-hams@ucsd.edu
Deane,
its interesting you have this problem. I bought a TM241A about a year ago,
and AM receive is really bad. However, reading in an article ( I think it
was in CQ) they said that AM sensitivity is bad thus you can only use it
near airports etc.
Now you say your second 241A does not have this problem and I realised that
there may be a change someone can do to improve AM sensitivity (perhaps
Kenwood did the change for later models). I looked in the schematics and
found nothing.
If you get answer on your question,please forward it.
Thanks,
Peter Vekinis, KC1QF

Be careful with in dash mounting that there is sufficient air circulation
around the radio (you may have to add a fan and a bit of fabricated ducting
as a friend of mine did). That little Kenwood gets real hot during transmit,
and the heat has to be carried away or it goes off frequency (and eventually
burns up).

Take a key and go along both sides of the car making big scratches. Now
it's not pristine any more, so you can get out the Black and Decker and
DRILL THAT HOLE. (The keying is optional, but if that's what it takes to
get your nerve up, do it, someone will anyway sooner or later.)

I just bought a Hallicrafter SR-46 6M AM rig at the Virginia
Beach Hamfest. It says it puts out 65 Watts, but I have been told that
a previous owner only got 10 watts out of it. I won't say how much I
paid for it, but I will say, it does light up and the knobs turn! What
can I say, it looked lonely, and I thought I might as well use all my
limited band privileges I can get. I now have 2M FM phone and packet,
440 FM phone, and 6M AM phone. Only 23 cm and 220 left to go.
No Antenna yet so I haven't pressed the PTT. Is 6M AM vertical
or horizontal?

Yep. Either spring for a duplexer, or run two antennas. It's likely to
be better to use the duplexer and a single centrally mounted antenna
than to try to use two antennas mounted in non-optimal positions.

(This discussion belongs on .policy; followups redirected.)
Ken, don't tar all coordinating bodies with your broad brush. The Texas
VHF-FM Society does not allow transfer of coordinations except from an
individual to a club, and that only because many clubs had their repeaters
coordinated by the individual trustees in the days when coordinations were
always issued to individuals. We do not allow the practice you're
complaining about. We also require trustees to renew coordinations annually,
and have procedures in place for revoking a coordination if the repeater is
in fact not on the air for over 90 days - but someone has to complain first.
I have no direct experience with coordinators in other areas, but we're not
all bad.

Sorry, it is legal. Private contractual agreements aren't overturned
by PRB-1, or any other radio related statute. Your only recourse is
to not agree to such restrictions at the time of purchase. Be sure
to tell the seller *why* you won't buy their nice house as well. The
only way to beat these restrictions is to make builders who insist
upon them lose enough business so they'll quit including them in
their deeds.

This is what the ARRL says, but what they neglect to mention is the
firestorm that followed those statements. As most of you know, the
country is divided on 2 meter band plans with nearly half going one
way, and the others going the other way, IE 15 kHz inverted splits
versus 20 kHz upright splits. What's not reported here is how rapidly
the FCC backpedaled from this position that the ARRL plan is *the*
plan once that situation was made known to them. Now they understand
that band plans are *regional*, and not handed down from on high by
the ARRL. Of course you wouldn't expect to see that in a ARRL publication.

Yes, such a secret society exists within the ARRL. Like the
Illumini, the Trilateralists, and the New World Order, this
secret society's mission is to undermine freedom, truth, justice,
and the American Way by imposing a rigid tradition on amateur radio,
centered around worship of certain beeping sounds.

Hi Bruce,
Name here is Sonny (Ka1esg) in New Bedford, Ma. Those guys were not pulling your
leg. There is such an organization, and they usually have them at the Ham Radio
Conventions. It's suppose to be like a horror story and if you sit through it
all at the end they will give you a secret password. The meetings are always
held at midnight in a very dark room. It was fun although I have only been once
and that was many years ago. If you get to Dayton I am sure they will have one
there, or if your in my area next weekend they have a Convention in Boxboro,
Mass. which is not too far from Boston, and I know for sure they will have it
there. Wish I could tell you more, but it's all a secret. Hi Hi. Take one in and
find out for yourself. 73 and if you care to respond my e-mail address is
mmello@umassd.edu
Bye Bye for now.. De Ka1esg Sonny now clear....

Kenwood Radio had a program a few years ago to get youth
interested in ham radio called 'Kenwood Kids'. There were free items
for the clubs that sponsored youth groups, and even a few large radio
donations to some lucky clubs. The Virginia Beach Amateur Radio Club
(VBARC), in Va. Beach, Va. started a youth group at that time and it is
going strong! Many of the members are the sons and daughters of hams,
some had their calls before the group started, some got them after
joining the group. Some still don't have a call, but are trying. One of
the youngest members of the group, David KC4ZHU, got his call in 1991
when he was eight. I hope this helps a bit.

You missed it. The dip is slight, a few millivolts, and you have to
measure it under load, not while charging voltage is present. The
dip is also short, continued charging will cause the surface charge
voltage to go higher after the dip occurs. Chargers using this method
of detecting charge status are generally pulse chargers that momentarily
apply a load and sample the cell voltage after each charging pulse.

No, for two reasons. First, air traffic centers have DF equipment that
depend on a steady carrier to work. This is used very often to find
"lost" general aviation aircraft. And second, keeping all those radios
on channel closely enough to be intelligble on SSB would be a major
chore. That's why ACSSB was invented, to allow a pilot carrier for AFC
(and compandoring). If a change were to be made, ACSSB would be the
logical choice.

The sad part about these covenants is that hams cannot seriously fight these
through market forces. For each ham that walks away from a home sale due to
antennae restrictions, there are plenty of non-hams who aren't bothered by
the restriction. What we need is what Georgia has- a law exempting hams from
any new covenants restricting amateur antennae.
Random thought:
Is antennas an acceptable substitute for antennae? I have to bite my tongue
to remember to use the latter. It just feels weird to me.
