Switching supplies vary in their responses to RF, and in their responses to
quickly-varying loads like an SSB or CW transmitter.  It just depends on the
individual unit.  I got a supply for $50 at a hamfest from "Switching Power,
Inc." that gives 40 amps at 15V (adjustable down to 13.8), 12 amps at 6v, and
6 amps at 12V -- each leg floating so you could stack 'em for negative-going
if you wanted.  It works fine.  You should watch your supply output under load
on a scope -- if there are spikes when you turn it on or off, or when the load
varies up and down sharply, watch out!

I'm looking for info on this chip (marked TBA 750 C).  I believe
it's an IF-amp/limiter/squelch chip, based on its use in a 2-way
radio.  I'd like to get pinout information, and possibly a data

Any suggestions?

Last week (Thu 09/24) I sent e-mail to the ARRL "front desk", using the

I received a prompt e-mail reply (about an hour later) stating that the

in my mailbox on Monday 09/28.

Can't get much better than that :-)

Well, I before even leaving for NYC, on Wednesday 9/30/92 I took advantage
of the AES sale and purchased an Alinco DJ-580T, to add to my collection
which also consists of a Yaseu FT-470 and a HTX-202.

Thanks to all who responded...  speaking of high prices... while in
NYC this past weekend, I noticed a lot of amateur radio equipment in
those "Electronic" stores that are abundant on Broadway and the surround-
ing area.

47st Photo (on 45th--Sound City) had a Yaseu FT-470 in the window... I
ask the sales droid if they had any (yes, I was this desperate!), he
didn't have any but said he could order one...  I asked him how much,
he said $499.99.  Is he CRAZY!  That's MORE than list (I think)... these
dudes are absolutely pathetic!

You can get the FT-470 from any reputtable Amateur Radio Store for less
than $399!  Ouch!

If you were located on the East Coast, an east-west propagation path
would be recommended.  .  Since you are on the West Coast and want to
have a shot at the maximum number of active countries, I wold 
orient the path northeast by southwest.  Europe is a tough path
for you but there are a lot of active countries on 80M.  Also this
gives you a shot at the early morning long path to Europe.
A single loop has a fairly wide 3db fall-off pattern so you wouldn't
miss the West Indies area.  The same goes for Japan.

However, to really get at the 80M dx on SSB you have to be able
to operate in the 3790 to 3800 window;  on CW most of the dx
is in the 3500 to 3525 area.

60-70 feet up for a wire antenna on 80M isn't very effective.
90-100 would be much better.  Have you considered a two
vertical setup?  I think this would be much more effective
than a single loop as you can get unidirectionality.
To get a low takeoff angle for the verticals, you would
need lots of radials-- > 80 at least.

Date: Sun, 4 Oct 1992 18:26:23 GMT
Distribution: na
Organization: Harris Semiconductor, Melbourne FL

Recently, one of our club members bought a Radio Shack HTX-202.  He has been
having trouble using the autopatch on both of the club's repeaters.  On one
machine we are using an ACC RC-850, the other has an ACC RC-85.  

When the user tries to manually dial or use the touch-tone pad test, the 
controller will not respond.  When he uses the autodial function of the
HTX-202, the controller will properly respond.  

On both repeaters, we tried the following touch-tone pad test:

  1. Enter the touch-tone sequence holding each key about 250-500ms 

  2. Enter the touch-tone sequence holding each key about 1-2 sec

Using a IC-25A and TH-77, both entries were decoded on both machines.  However,
when using the HTX-202, ONLY the short entry sequence was acknowldged by the
controllers.

Has anyone else observed this problem with HTX-202s or ACC controllers?  I 
have been using these controllers for 5 years without a failure and have never
known them not to detect dtmf tones with a variety of radios. 

I have not tried looking at the HTX-202 for *twist* or stability... yet :-)

My experience with ARRL and e-mail has been quite positive.  Once I 
asked for some information electronically, and I had an e-mail answer 
within 24 hours and the paper copies of what I had asked for via slow 
mail within a few days.   Another time I just asked for a followup to 
an earlier post.  Again, the information was returned promptly, and I 
sent in my paper request to headquarters (they needed a check for what 
I wanted) and I received that material too within about 10 days to two 
weeks.  Anyway, as far as I can tell, the e-mail responses have been 
quite good, and have given us (me, at least) much greater access to 
headquarters people than would otherwise have been the case.

The DJ580 remote control speaker-mike has some simple capabilities: I
believe you can raise & lower the frequency, and one or two other
functions. (I don't own one, or I might be able to figure this out
myself...) Looking at the DJ580 schematic, it appears that
this control is implemented with only a single wire, which goes
right to the processor.

So, the big question is: How are the control functions implemented on
this wire, and can other functions also be accessed remotely?

With all due respect, the standard TNC, and the BNC use the same shielding
mechanism.  Except for the screw vs bayonet, they would connect to each other
just fine.  They are really the same connector on the inside, where it counts,
and have the same RF leakage characteristics.

There is a high performance version of the TNC that uses a non slotted shield
connection that is good to somewhere in the 10's of GHz, but it is extremely
expensive, and not in common use.

The TNC has some advantages over the BNC.  It has no spring in its mechanical
coupling, and as such it is more rigid.  It is waterproof.  It comes with an 
option for being safety wired to its socket.  In general, a TNC will take a lot
more abuse than will a BNC.

If you are having trouble with your BNC's at 1GHz, you probably need to find a
new supplier.  Amphenol's and Kings, will work just fine.

a new 2m HT.  In this months QST, there was a review of the availble 2m
radios.  Among them is the ICOM-2SRA, which got good review.  I seem to
the exact person that the unit was designed for.  I am looking for any 
comments users have with this unit, both as a HT and a scanner.  For 
example, would it make more sense to buy a KENWOOD TH-28A and RADIO 
SHACK Pro 38 (?), there 200 channel desk unit.  Does the '2-SRA have
a seek mode?  How fast is the scanning of programmed channels?  Any insight
that someone may have, both the amateur world and the scanner world would
be appreciated.

Thanks,

Since the freezer uses negative tempreatures, things work backwards... 
you'd need to set the battery on a piece of concrete for it to work.

Seriously, even if you could get it working again, it's likely that the 
capacity would be so diminished that it would be pretty much useless.
