Do any of the current or classic "satellite" HT's (FT-51R, IC-W32A, etc)
allow you to create a single channel with a FM bird rx/tx pair in full
duplex?
I.e. I turn one knob and get 435.310 145.875
{click} 435.300 145.880
{click} 435.290 145.885
I could do this with the 20 DUP channels on the Ft-100D.
Even though the IC-W32A has two "knobs", it looks like (from the manual)
only one can be in memory mode at one time, so TX would be in VFO mode,
and the other would be in channel mode. Is this correct?
So for each change (AOS, MID, LOS), I have to turn both knobs
one click, correct? Even if I can have memories on both sides,
I still have to turn both knobs -- If so, why wouldn't I just use a
VX-170/VX-177 pair of HT's, and turn both knobs?
I can program my DJ-V5 to have the "odd split" (TX144/RX432)
single knob channels, but of course, it is not full duplex.

IIRC, the IC-32A/AT/E does, but it's been a long long time since I used
one in that manner...

I can't comment on the various HT's but I would think that you'd want the TX
freq in memory and the RX freq on vfo. That's how I use my TH-F6A (not a
full duplex HT).

Bill,
The Alinco DJ-G7 is full duplex and has 100 cross band memory channels that
can do Satellites. You can setup 5 memory channel pairs to cover first
approach, near approach, Closest position, near departure, far departure.
Then just click through the memories as the satellite passes. Another DJ-G7
feature is it can also do 1 watt on 1.2GHZ uplink to AO51.
I suggest using 5khz steps on 435mhz so it does 5 memory sets.
Good luck,
Don - kd6ire

437.550 MHz. This should add it to SATPC32:

If you are going to be listening for ARISSat-1 on the 12th, and use SATPC32,
you will be using the ISS for antenna tracking, but you will need to add a
few modes in the DOPPLER.SQF file for the ISS:
ISS,145918.5,0,USB,,,0,0,BPSK/CW-2
ISS,145950.0,0,FM,,,0,0,VOICE/SSTV
ISS,145938.5,0,USB,,,0,0,CW-1
If you use something other than ISS, such as Zarya, then substitute that so
SATPC32 will know what you mean.
These will appear along with all the "real" ISS modes. The FM frequencies
should be good, and the SSB modes as usual will need a little tweaking.
Assuming your rig is calibrated, you should be at least close enough to hear
the short transmit periods.
73s and good luck,
Alan

I was wondering if anyone has scene the article about using a diplexer (I
think that's the right name) on both ends for a satellite setup? One where
the two antennas are then a single feed then another one to split things up
again by the radio. I think it was in QST but can't remember the issue or if
someone has used that setup I would like some input ......Thanks and 73's

I am having a party on April 12 celebrating Yuri Gagarin and the activation
of ARISSat-1. It is from 6-10PM PDT April 12 (0100-0500 GMT April 13).
Anyone out there want to "visit" a bunch of giddy Californians via
Skype/Skype Video in that time period?
We are already scheduled other video linkups from 7:05-7:10PM and
9:45PM-9:55PM PDT ...
You do not need to "offer" anything special ... Just hearing/seeing you as
we commemorate this date would be GREAT!

I used that arrangement for several years with great luck. Just be sure the
insertion loss is low. It had great mode J harmonic rejection.
I used combiners from Comet (model 4160)

The Alinco DJ-G5 will do so. I think that the Yaesu FT-470 did too, but
it's been so long since I owned that radio that I can't say for certain.

Not quite... the usual understanding of the terms is that a duplexer
provides isolation between 2 devices (typically a repeater transmitter and
receiver) operating in the same band, while a diplexer is for devices in
different bands, ie, 2 meters and 70 centimeters.

Not quite; a duplexer is typically used where you want to TX and RX
simultaneously on quite close frequencies like in a repeater, and a
diplexer is more commonly used where you want to TX *or* RX on two
different bands.
So for combining a VHF and UHF aerial into a dual-band receiver, you'd
use a diplexer. For separating the TX and RX frequencies at a repeater,
you'd use a duplexer.

Either term is equally correct.
The prefixes di and du both indicate TWO, so it multiplexes two signals. A
triplexer multiplexes three.

Since we are beating this horse.
Does anyone have any pointers to units that allow more than three inputs
or outputs or commercial higher power units? I want to run HF through
2.4g down a single hardline and breakout each band at both ends. This
would be used instead of a remote antenna switch.

Sounds like a tall order.
You want <30MHz, 145, 430, 1300, 2400 or do you also need 50, 220 and 900?
