Subject: Aircraft/Marine/Ham radio equipment: info wanted
To: ham-equip@ucsd.edu
I have a friend that is taking a extended backpacking/kyaking trip to the Northern
part of Alaska. He was told that he needed a handheld Aircraft band
receiver. Does anyone make a handheld that would operate on the aircraft
band as well as the marine or one of the ham bands? Can a modifcation
be made on a radio to make this happen? Who makes sturdy aircraft/marine
radios? Does anyone have one they want to sell for a good price?
Does anyone have a list of frequencies that it would be advantageous to
be able to transmit/receive on for the Brooks Range and Artic Ocean area?

Subject: Bought Standard HT recently?
To: ham-equip@ucsd.edu
In April, I purchased a Standard C558A from HRO. Last week, I
saw an HRO ad, expiring July 15, offering a free speaker/mic
from Standard with proof of purchase of the C558A. I called
Standard to ask how long the bonus had been in effect and was
told April 15 to July 15, but that they would probably act
favorably on a request with an early April purchase date. It turns
out I bought mine on the 16-th, so there's no problem. I'm a
little disappointed that HRO didn't let me know of the bonus.
While they could have been unaware of it on the 16-th, they
have my purchase in their computer and could have done a quick
search when they were notified of the bonus to catch me and
others like me.
There are similar bonuses on other Standard HT purchases, See
the HRO ad in the June QST or the Standard ad in the May QST.

Oh no! Of all people Hallicrafters should have know better than to say
`megacycles' instead of `megacycles per second'. They must have been some second
rate company. No wonder they went out of business; probably all you Mc/s
people boycotted them in protest.

ICOM was having a coupon sale then. In April and May, the street price went
back up to $500. (HRO was asking $499. I know because I was looking in April.
I got a Standard C558A, instead.) I called around yesterday and discovered
that ICOM is couponing this month so the price is lower again and the unit
is readily available at a reduced price. I'll bet the people who bought
them in April and May are going to be plenty upset, though!
You're right in your implication that it's not necessary to go to a Tour
America stop to get the lesser price and the news of the coupons probably
wasn't worth posting.
This *does* raise an issue worth discussing, if only there were something we
could do about it--namely, the way many manufacturers jerk their prices around
to make it difficult for the newcomer to the hobby to figure out what's going
on.

Version 7.x is correct.
When I teased Kantronics' Karl Medcalf (WK5M) about their ability
to make new versions faster than I could buy them (I just got
version 5.x late last year!), he just shrugged and suggested
I buy the enhancement board.
I saw that board for $89.95 at last Sunday's hamfest.

She prefers the HT-220s to Micors.

Its a nice little SSB rig. I've had one around for 10 years or so with
no problems. I don't care much for it on CW though. Too many signals leak
around the CW filter causing high pitch birdies. For this reason I find
it difficult to use on CW without an audio filter. Perhaps they improved
this on later models.

Ed: Love my 757gx. Bought it used with the HD p/s and mobile mic for $800.
That was in '88 I think. This rig was VERY clean, like new, low hours,
orig boxes, etc. (and i knew the guy). I cant say enuf good stuff about
this rig. Last year I made a HUGE improvement: put a Heil element in the
desk mic. This year got the Heil headset-mic combo. Don't know current
price for clean used rig but don't buy the solid-state p/s (it's noisy).
I would guess current price about $600-700.(with or w/o p/s). Check the
Yellow Sheets....always lots of good stuff.
Good luck --- 73, N9AVP

Subject: Recommendations for 2m/440 mobile wanted
To: ham-equip@ucsd.edu
(My apologies to those who have previously read this in rec.radio.amateur.misc;
I forgot to crosspost it here.)
I'm looking for a smallish 2m/440 mobile radio for use on a temporary basis in
my car. Basically, I want to use it as a very transient system -- cigarette
lighter power, ground clip to chassis, mag mount antenna on the roof, unit
Velcro(tm)ed to my car's carpet.
Possible units:
* Yaesu 5100. My current leading frontrunner, as I want dual in-band
capability and don't need a detachable faceplate since the whole unit
will always be coming with me.
* Kenwood 732/733. The 733 is newer and is price-comparable to the 5100,
but AES has a nice price on the discontinued 732. The Kenwoods lack a
backlit DTMF mic, though (it seems like it would be a nice touch at
night.)
Usage will be for commuting and SKYWARN.
Basic questions on these (or other recommended units):
* Do they have built-in speakers of any type, or do I need to add an
external speaker to the list?
* Do most newer units have built-in and/or defeatable antenna multiplexers
(e.g. just hook up a dual band mobile antenna and go)?
Please reply via email, and I'll summarize if there's interest. Please feel
free to tell me if my proposed system won't work as well.

The Opto board in the MFJ analyzers is the frequency counter, and is as
stable as any of the non-ovened counters. The oscillator, on the other
hand wanders all over the place. I cleaned mine up a bit by resoldering
most of the joints (touch the iron to a joint and watch the rosin boil out...),
clipping excess component leads, and soldering the variable cap to the
board. More of MFJ living up to their Mighty Fine Junk name. It still
drifts a bit, and the cap leaves much to be desired, especially on the vhf
setting. It still is a useful tool, as long as you keep an eye on the
frequency.
I also added a resistor and diode across the power switch so I can charge
the nicads in mine without unscrewing the case...

Subject: TS-140 Connectors
To: ham-equip@ucsd.edu
Hi! I am trying to help an American ham radio operator in Africa get
his Kenwood TS-140 radio set up on packet radio with a KAM Plus. His
brother and I are sending the TNC to him, but we don't know what kind of
connectors the TS-140 uses. More specifically, does the TS-140 use the
older 4 pin mic connector or does it use the newer 8 pins connector?
Also is there an accessories socket on the back that could be used to
supply 12 volts DC to the TNC? If so, does anyone of you know what kind
of plug is needed and which pins are used for +12 volts and ground, so
we can purchase the connector and prewire it before sending it to
Africa. The radio is literally in the bush with a generator being used
2 or 3 hours in the evenings. It is difficult to set up a solder
station, so we are trying to make everything "plug and play" when we
send it.
Thanks in advanc for your help. Please email any information you have
on the TS-140 connectors to:

The Yaesu FT530 was the first radio I ever owned....picked it up the day I got
my callsign...just over a year ago now.
It has its problems. The first was the antenna, which Yaesu sent to me free
right after they got the warranty card. The second is some minor firmware bug,
they offered to swap the radio at no charge (except to ship it to them)...but
I didn't feel that the problem was serious enough to give up my radio for a
few days.
The radio has been running solid as my main packet radio (on my Packet BBS) for
the last several months....it does get a bit warm.....I could use a little be
more umpf to get in more solidly with the node.
I'm thinking of getting another radio soon, and it'll probably be another one
of these radios......I haven't quite decided if it has to be a dual band HT or
not.
The only activity on 440 is linking, and people crossbanding so they can get
to the repeater from poor locations....but our new local area repeater should
solve that problem. If having a HT at 0.5W can talk to a person at the other
end of town to a person with an HT in his basement at 0.2W....it'll do even
better with 20W, though there is some question about its receive sensitivity.
