Ray:

I got the IC-2GXAT.  I also have the IC-W21AT.  Accessories fit both HT's.
There is a keyboard mod to open up RX from 118 to 179.  I like Icom.  The
T21A has 100 memories vs 2GXAT's 40, and I think it receives 70cm - a tease.
The 2GXAT is a great performer.  I got it because I wanted a backup HT.

So maybe it never occurred to someone there might be a secret society
based on this instrument of torture.  But then it is a secret society.

I'd say more, but it is not permitted.

Just pick up any power supply from any good electronics store.... make shure
it can give you at least 8 amps of draw. Tell the electronics store guy what
you are using it for and he'll give you good advice.

I didn't know the 530 would let you split across bands on memory mode.  This
is exactly what we need it to do, and we don't need to receive on the tranmsmit
freq (we're not using the crossband repeat to boost up to a repeater; we're
using it as the repeater itself for areas that have no amateur repeater
coverage).

Thanks...

Subject: PRB-1 IGNORED!!!
To: [e-mail]

I've lost track of the battle for our antennas since I won mine on
September 21, 1990.  I didn't expect it to stop there or get better
just because of a victory in the 6th circuit.  The ROCKY RIVER, OH
case is cited 748 f.supp.1241 .  The second of three court orders
wasn't published but they were posted here in Oct. and Nov. of '90.

If you talk to a league volunteer counsel, they should already have a copy.
They should talk to you for free initally, but once you get to court
the meter is running, perhaps discounted, but still running.  I've
read of a few cases which were settled out of court with expenses
partially recovered, not recovered or a court order granting some
recovery.  There isn't much guarantee here.  My recovery of $14,091.05
was probably the result of "not receiving a fair hearing" rather than
PRB-1.  I'm still out about two grand in the end.

None the less, talk to the league vol. counsel and read the mags for
the results of other cases, especially the peacefull settlements
and favorable legislation.  They went ballistic in RR and tried to tighten
up the code even more.  The action they took here was denying the tower
because of a neighbors protest.  A most efficient way to burn over
$32,000 of your tax dollars (it cost them over $18,000 plus what I
recovered.

Drop me a line to tell me the whole story or where to find it all.

big plate modulator?

some specs from my copy of Collins Pro Line II Comm/Nav/Pulse System
instruction book, 3rd edition 1st revision (1986..or so..but things shouldn't
have changed that much...)

Collins VHF-21( )/22( ) VHF Comm:
    size    3/8 ATR short dwarf
    height    85.3 mm
    width    95.3 mm
    length    355.6 mm
    weight    2 kg
    power consumption
        receive: 14 W (0.5 A @ 27.5 V dc)
        transmit: 165 W (6.0 A @ 27.5 V dc)
    transmitter
        output    16 W minimum into 52 ohms resistive
        modulation - 85% with less than 15% distortion; 95% limiting

modulator is an audio compressor, a comparator, and a switching amplifier with
low-pass filtering of the output. output from the compressor is applied
through a modulation depth control to the comparator where it's superimposed
on the dc bias voltage supplied by the power control. the dc signal is
compared to a 106.7 kHz triangle wave signal to make a 4.5 V p-p 106.7 kHz
pulse-width modulated signal.

the output of the comparator goes to the switching amplifier and output is a
25 V p-p pulse-width modulated signal that's low-pass filtered resulting in an
average modulated DC required by the RF power amplifiers.

the transmitter is a four-stage device. the driver collector recieves power
from the modulator and the +16 V power supply and the final amplifier gets all
of its power from the modulator. looking at the schematic there's not much
iron in the beast at all...

not too bad -- some iron in the collector rf chokes in the transmitter...

Well, I can enlarge on the subject and in the whole truth. I have developed
thousands of residential properties in Southern California from the Mexican
border to San L. Obispo. I've never had any contact with any cable TV
people!

Guess I'm missing out on some fantastic kickbacks!
