Subject: AM Sensitivity Problem with TM-241A ??
To: ham-equip@ucsd.edu
I've got two Kenwood TM-241A 2m transceivers. I've had one for several
years now and use it regularly for AM receive. I'm happy with it. I just
bought another one and it can barely pick up anything on AM. The two rigs
definitely have two different sensitivity levels when it comes to AM. FM
works fine on both rigs. Has anyone else experienced this type of problem?

A friend of mine had one recently and had trouble keying a linear with the
keying output. He had to increase the drive into the keying output xistor
to sink current over about a milliamp. Has anyone else had this problem?
As usual, the distributor had no clue.

well... i'm in the midst of this too... and the old units used 110vac
instead of the current 24vdc... so your receiver may also need a
24 v supply.
i just bought a genie trans/recv set at Home Depot ($36?) ... but they
didn't stock the power supply.
if you dial 1-800-ok-genie they'll supply the name/number of local
nuts-and-bolts vendors of these things. one i tried said it was $50
for the trans/recvr set, plus about $24 for the power supply.
the genie set does *not* come with schematics, but they do list the wire
colors/functions.

They actuall make a special drill bit for mounting the NMO antenna

might be able to get them to pop the hole in the roof. Other wise use a
3/4" chassis punch or pick up a "Unibit" these are available in a 3/8"
shaft. They start at about 1/4" diamater and progress in steps to 3/4"

Subject: Motorola Sabre HELP
To: ham-equip@ucsd.edu
Harold, sri I can not see your internet address, hence I can
not reply directly. The Saber has PC programming software.
It also requires a Motorola interface for PC to radio. This
interface can be used for many of the Motorola radios/repeaters
etc. The software / interface are not "freebies" from Motorola.
Also, considering the cost of the Saber - that seems a strange
choice for a ham rig, and it only covers one band and proably not
on the ham band without a MOD of some type. Do you have that MOD?

Uh, OM... have you ever USED an HTX-202? Evidentally not, judging from
your comment.
The 202 is a pretty good ham-band-only radio. Don't buy one if you want
to listen to cops or paramedics or airplanes, because it won't tune out of
the ham bands, either on purpose or accidentally. The receiver is tight,
to cut down on out-of-band images and other problems that make a lot of
the wide-band receive HTs sound real bad in metro areas. Using my
two-year old 202 in downtown
Fort Worth (I don't work for Tandy, BTW), I don't hear a lot of the
intermod and images, that I DO hear when using my Kenwood dual-band mobile
radio, and both of 'em are hooked up to good mobile antennas.
As for the plastic case, suffice it to say that complaint is nonsense. I
can't think of an HT made with a metal case, today, and probably wouldn't
want to lug it around, if I could. My 202 has been handled quite
realistically (pardon
the pun! <g>), and still has no dents or gouges, and only one small scratch
(from falling off the roof of the car at about 15mph - but that's another
story).
The audio on the 202 seems to me to be quite sufficient, louder than that of
my Icom u4AT. The transmit audio, being true-FM, has been complemented
more than once (the deviation was right at 3.8 kHz when I put it on a
monitor after I got it ).
I'm happy with my 202, and I paid more for it than $239. And though I
also got the extended warranty, the regular warranty period is long since
over, and I've yet to have to worry about getting it serviced, because
it's never needed it. And, if my XYL can drag it around the country on
her business trips and not break it, I consider one FB rig.
Again, the warning: don't buy the 202 if you want to receive or transmit
outside of the 2 meter ham band. Not CAP. Not MARS. It won't do it. This
is a ham band radio, designed by hams, for hams, and I think they did a
pretty good job of it.

Commonly believed, but not true. The HTX-202 is made in Korea, by a firm
that's not known for producing other amateur gear. The only Icom-ism is
the fact that the HTX-202 and 440 brother will accept the larger Icom
batteries used on the IC-02/03/04 style radios.
