                            Announcement
                  VSS: Vintage Solid-State Maillist


Purpose of the list
 The Vintage Solid-State (VSS) maillist is for the discussion
 of older solid-state communications equipment that is
 of interest to the radio amateur and other experimenters.

 This equipment includes test equipment (signal generators,
 oscilloscopes,...), receivers, transmitters and accessories
 built in the 1960's and 1970's.  Manufacturers of interest
 include Hewlett-Packard, Tektronix, Motorola, Racal,
 Heathkit, National, Atlas, Drake and others.

 Discussion will cover what's available, recent prices,
 what to look for, what's good and what's not, maintenance
 and restoration, where to find documentation, etc.


List maintenance
 The VSS maillist is managed by an automatic list processor.
 Each list member is responsible for sending appropriate
 subscribe/unsubscribe commands to the list processor to add
 his/her name to the list.

 5 amps continuous?!?  That's one helluva draw!  These cells
have a fairly high internal resistance (like regular alkalines), and
at that draw they just plain won't work worth squat.  They will work
best in situations that draw about 100mah average or so (maybe a
little more, and maybe less for the AA cells).
 Use them in situations where you would usually use an alkaline
cell (and expect *that* to work well).  We use them in an HT that's on
a lot, monitoring probably 8 hours per day and talking (medium or low
power) for maybe 5 minutes per day, and they last us probably a week
or so.  Nicads *sometimes* lasted the whole day.  Alkalines last even
longer, but get expensive fast.  The deep-cycle 105AH Marine battery
lasts a very long time but is somewhat less portable ;-)

For what its worth, the spec sheets showed up from Ray-O-Vac today and it
shows a capacity of 5.5AH for the initial charge and 90AH over a 25 cycle
life.

* OK OK OK OK * I stand corrected, informed, and generally a better form
of life than I was when I first posted the item. I did not realize that
this was the nature of Alkaline cells, and the four cells I tested have
been relegated to a flashlight where they are basically happy. Live & Learn!

You should try rec.audio and rec.audio.high-end - you will get better
information there. Amateur radio is not know for high quality audio.

Subject: HT Recs out there? (TH78A)
To: [e-mail]

A comment on the TH78A. I think it is a great radio with the following
exceptions: 1: Cannot be used on external antenna on 2M due to horriffic
                intermod problems.
            2: The battery release latch will occasionally trip when wearing
                on your belt, resulting in an unplanned battery drop test.

To: [e-mail]

HI ! I'm looking for PC Hardware to communicate by radio.

I'm specially searching for low radio power cards (e.g. 100 mW),
  because I want LOCAL COMMUNICATIONS.

And I'm desesperate!
 I only found 2 pieces of hardware: NCR / AT&T WaveLAN   and  TxCOM .


Pliiiiiiiiiiiiize could you send me informations about differents products
 AND / OR where to get informations about them.

THAAANNNNNNKKKKKKKKK YYYYYYOU !
C U SOON.

Bird is a good source. :-)

Dielectric Corp slugs will work too, and may be more available, or
cheaper. Most of the major two way and ham suppliers list slugs in
their catalogs.

Amateur Electronic Supply or Ham Radio Outlet should have
them... but they are new and you pay for new oats.

There should also be lots of this kind of stuff at Dayton,
if you can wait, put up with the parking, and so on.

Subject: Pkt satellite receiver card for PC?
To: [e-mail]

[Q 1]:

I would like to know if there is an ISA-bus card which acts as
a satellite receiver that I can plug into my PC.  My "project"
involves a satellite dish with coax cable receiving a packet RF
transmission which I would like to run into my PC for decoding.
The data would then be displayed under Windows3.1/NT/whatever.

[Q 2]:

What are Phil Karn's KA9q C functions?


If my questions don't make sense it's because I'm new to this
and don't know much about packet radio.

Thanks

Has anyone built their own remote cable for their Kenwood TM732 or 741?  I
have a hard time forking out $50+ for a piece of wire that should be
included with the radio in the first place.  Thanks...

Subject: rotator ???
To: [e-mail]

I wonder if your rotor isn't just an induction motor that has a run capacitor
which determines the direction and a small gear train to reduce speed an
increase torque. Syncro's have littel torque not enought to turn an antenna.
The cost of these were quite high.  Most rotors had some other type of system
to get direction.  One used a set of contacts that made and broke with motor
rotation. Kinda like a KERCHUNK sound at the indicator end when the rotor
was turning.
   The other had a variable resistor mounted in the rotor and sent back
some signal to a meter in the control. Radio Shack had anoter type that
had a syncronus motor in the control unit which moved a direction disk at
the same rate as the motor on the antenna.
   Most all of these motors were run on 24 vac. (the stepdown transformer
in the control unit 120 to 24vac).  This let you use low voltage wire
and not run into complications with the 120vac line voltage. The capacitor
in the control unit is an A.C. motor run capacitor. If it gets weak the
rotor torque goes way down.
   Hope some of this was of help
