Tony, I've a Drake R4B and while I don't remember the diffs to
the A model, they are both very nice recievers with mechanical
filters for selctivity. I prefer them to the R4C in the it
has crystal filters that are hardwired to the mode switch where
the A and B give the ability to set the mode to AM and the filter
to CW and so on. (CW selectivity on a very qrm'd SSB signal
can make a major difference...)
I'd say 'go for it'... if its reasonably clean and appears to
work reasonably.

To: ham-equip@ucsd.edu
A few years ago, there was an article in QST about the CMOS Super
Keyer II. I bought the kit from Idiom Press, and put it together in
a few hours. It's a 1 chip microprocessor, and you just add some
resistors, switches, a pot and battery holder. Works great.
It has 4 memory positions, and is controlled by Morse commands
on the paddles. Speeds from 6 to 60 on the pot. Works great
in contests, and batteries last for years. Send a sase to Idiom
Press at Box 683, Deerfield, Ill, 60015 for info.

Subject: HTX-202 TT PAD ADJUSTMENT
Radio Shack has just released an adjustment to the HTX-202 Handie....
It has to do with the PTT tone volume.. It goes as Follows
If you have trouble getting the touch-tones on the HTX-202 2-meter Ham Radio
Transceiver (Cat No. 19-1120 ) to work with the local Repeater, try resetting
the unit's touch-tone audio level.
To do this, you can adjust the touchtone pot (RV 1001) down until the tones
don't decode, then up again until it JUST works. (Simply tuning down is NOT
as reliable as this metho You uld make NO other adjustments!
Also, many repeaters will read back the tones once they decode properly. If
you are unsure how to do this, you can find out from another repeater member.
This is all R.S. would have to say about there HTx-202. If you have had any
problems with using the phone patch, this should cure it. Some have been
setting the << Auto Reply >> function in the main setup to << ON >> to
cure this problem. If you have, set it back to << OFF >> before adjusting
(RV 1001) pot. Hope this helps..............

Anyone out there using the MFJ 1796 vertical?
If so I'd like to here comments on them, pro or con.
Like how well does it load, ease of installation, construction quality, weatherproofing of coils, connections, apparent efficiency, etc?
Thanks in advance,

To: ham-equip@ucsd.edu
Hello. I'm not suer if this is the right group to post in but it's worth
a try.
I just bought a Mr. Microphone and I was wondering if there is anyone out there
who has had any luck making so adjustments to it such as:
1) Adjust the frequency of the transmission to any great extent (different
band?)
2) Increase the power output a great deal?
Any ideas would be appreciated!!
thanx!!

Subject: Need IC211 manual/repair help
To: ham-equip@ucsd.edu
A friend recently purchased an ICOM IC211 2 meter
all mode radio with the remote vfo box (RM2).
Unfortunately it didn't come with manuals, and
now has developed a couple of
problems. One is really low output (blown final?)
and the other is a tendancy to hop frequencies
while in operation (sometimes to 144.0, sometimes
inverted on the repeater channel).
He'd really like to track down a manual, a service
manual, or at least a schematic for the beast, along with
any information about these problems (i.e. are
there some typical failure modes in these
radios, like the IC22S grommet problem?) Probably
there is some useful information on mods and
stuff out there also that would be of interest
too - I know these were pretty popular and
there were some front end mods for them.
He doesn't have net access, but I can relay to
him or provide phone information.
He's of course willing to pay copying costs,
mailing, etc.
Thanks in advance

Well, after 3 weeks of perfect operation with my third 742A, I decided to
try the S-meter squelch mode again. Worked great for about 10 minutes, then
the display froze up and it shut off just like the second radio I had. Now
when powered up, it displays -on- for a few seconds and shuts down. The key
sequence for resetting the cpu doesn't help. So it's back to HRO again.
I'm getting really tired of this.

^^^^^^^^^^^^^
OK, now that we're all sure of which product has the better receiver etc.,
Yaesu has a brand new entry level transceiver called the FT840.
At $795, I'm pretty impressed with the one I have, but I'll leave the product
reviews / comparisons to others.

Actually, pvalko, it isn't obvious that a Ten-Tec PTO beats a synthesizer.
Certainly, Ten-Tec does have reputation for building exceptional receivers,
but I'm not one to simply assume "it is a Ten-Tec, it must be like all the
others".
I was looking for some objective numbers rather than religion :-)

I recently bought what appears to be a 4 port microwave delay of some sort.
It was manufactured by MCS of Monrovia, CA, is a model # CO-9540 and has
an illustration on it that appears to be a diagram for a 4 port network
in a diamond configuration with the leg between ports 3 and 4 as a delay
line. Outside it's just a grey box with 4 Type N connectors. Inside 4
pieces of hardline are connected between the N's.

This sort of thing is already a problem. I saw Icoms on construction
projects as long ago as over ten years ago, thumbwheels and all.
Some of these radios were RENTED from outfits that were in the
two-way business and should have known better. Take a look at
whats in 47 CFR ... argh. That volume of the rules has hidden itself
in this mess. Its the first volume of the FCC R&R and it has
the rules for "type acceptance" as well as approved, notified,
and so on.... These rules have been made progressivley tighter
just because of this crud.
