Hello Domenico I8CVS
Tnx for your suggest very appreciated.
Yes I agree with you, the transverter needs to have a stable oscillator to
work (ocxo, tcxo) and a pa is needed today done also with the semiconductor
like module or mosfet.
On this last issue I have many project available in my lab.
Coming back to the transverter, do you think that the IF in VHF is suitable
also when I'm working in mode L/S where the Smode is done through a down
converter 2400/144MHz?
Sure, have a radio with a third band solve all the problems, probably IC910
newer or the glorius 790.
I'm scratching the head to take a decision..

There is 9.2 volt DC :( looks that the 7806 is defect. But one thing
that puzzles me, i don't see a connection from the negative site of the
ac-dc diode bridge to ground.

Hi all,
I'm selling my Kenwood TS-790A with 1.2ghz module, voice module, matching SP-
31 external speaker, and (NIB) IF-232 computer module.
I'm basically selling most of my gear due to failing health.
Great full duplex satellite rig!
I have the original box for the radio but I'm not sure if I have the speaker
box.
I do have the manual but it's a bit dog eared from use.
Sorry, but I will not seperate the package.
Cosmetically, I would rate the radio an 8+ on a scale of 10 only because of a
very small scratch on the far right side of the display. If you didn't know it
was there you wouldn't know it. It's really not worth mentioning but I try to
decribe everything the best I can.
Also the plastic carrying handle on the side has been romoved by a previous
owner.
The screws are still there but the handle has been removed.
Electrically, the radio is a 10. NO problems whatsoever. It meets or exceeds
all manufacturers ratings.
Will sell all for $1300.00 plus shipping.
Thanks for looking,
RoD

There is an even cheaper way if you like to build your own.
Paul, W1GHZ, has a set of transverter boards that can be used on 900MHz
to 3.4GHz and are CHEAP to build if you like homebrewing.
I have the 900MHz and 1.2GHz boards and they have cost me about 150
dollars to procure parts and the boards so far not counting the parts
that I have on hand in the junk box. You'll have to look at providing
your own sequencing, enclosures, and connectors for these based on how
you want to.
Pauls page for the transverters is:
http://www.w1ghz.org/MBT/multiband.htm
Hope this is something that you might find useful and consider them.

Mario,
My downconverter is also a homebrewed 2400/144 MHz and I have used it
for AO-40 where the analog downlink was 2401.225 - 2401.475 MHz and
middle beacon was 2400.350 MHz so that only to tune the IF from 145.225
to 145.475 MHz was necessary.
In order do not interfere the receiving IF while transmitting I was using an
IF from 144 to 145 MHz to drive my 23 cm transverter and get out from
1269.250 to 1269.500 MHz for the uplink into the L1 band or 1268.325
to 1268.575 MHz for the L2 band but obviously two diffent switchable
XTAL's where needed into the transverter because time to time for the
mode L/S the transponder uplink was switched from the L1 to the L2 band.
The above complication was justified at that time because AO-40 and the
previously launched satellites OSCAR-10 and OSCAR-13 where the only
HEO satellites covering the most part of day time for many and may hours
every day.
As you can see any transverter with an IF falling into the amateur band
has problem for satellite use full duplex and also for frequency agility in
terms of changing quickly many operating frequencies in a quick time.
Transverters are good if you use the same frequency for RX/TX as for tropo
or meteor scatter or EME but for satellite use where the operating mode
novadays are many and they changes every week a transverter has many
limitation.
For the above reason I strongly recommend to receive the S band using the
actual downconverter and look for a second hand tranceiver for the rest of
it.

Hi Jan, PE0SAT
OK the 7806 is defective and must be changed but since you have
to open the controller of G-5600 I suggest you to improve the
regulator performance because the original capacitor C9 0.01 uF at
the regulator output is a very small bypass capacitor.
Solder a ceramic capacitor of 0.1 uF in parallel to an electrolitic
capacitor ranging from 1 to 10 uF and solder it both at the input
and as well at the output of the regulator as this cure will prevent
possible autoscillations of the regulator itself in a wide frequency
band.
The negative path of the bridge to ground for the regulator Q2 is
through series diodes D5-D4-D3 and ground so that a drop of about
0.6 x 3 = 1.8 volt is developed and this is made to get a minimum
voltage of 1.8 volt and not 0 volt when the wiper of the 500 ohm
potentiometer is fully grounded.
The negative path of the bridge to ground for B1 C1 and B2 C2
to supply the +/- voltages to the operational amplifiers is through
the series transistor Q1 and zener diode D2
The negative path of the bridge for the coils of relay RY1-RY2-RY3
and RY4 is directly connected floating to the bridge and insulated
from the ground.

Very interesting concept! Probably not much in the way of thrust, but the
amount of "fuel" that can be created from a little water is pretty large, and
we have lots of time.
But, tell me, in zero gravity, how is the gas separated from the water? On
Earth is just floats to the top, but that doesn't work in outer space. Is the
whole thing spun?

Hi,
I was searching Google for the EDC-24 Alinco charger, and your message below
came up.? So happens, my DJ-580T EDC-24 charger has failed, and I can't find
one anywhere.? All I need is the trickle charger, and new chargers are > $50.?
If it still works, I will pay postage plus $10 for your trouble.? Do you still
have it?? Thanks,? ????? Earl Deason??? K4YTK??? Huntsville, Alabama

My Alinco DJ-580 met with a terrible accident and is no longer with us.
Seriously, the radio was destroyed in a freak mishap. I have the following
accessories that I will send to you free if you can use them:
Alinco EDC-43 12-volt power cable assembly
Alinco EDC-24 battery charger for ni-cad batteries
Alinco floor plate (battery cover) for use when operating the radio without
batteries
EarTalk remote microphone and earpiece with PTT for the DJ-580
I will send to the first request I receive - respond direct to me - not thru
BB. I'll let you know when they are gone.

Hi Mario,
For L band uplink I use an SSB Electronics UTM 1200DLX. It generates
about 15 watts out for 5 watts in. It has a 144MHz input. If I am
working mode L/S, I will use my FT-817 for the mode L input, the 5 watts
(about 3 to the UTM 1200 on the roof) works fine. That leaves the
FT-736 for the 144 MHz IF for the S band downlink. Mode L/U would allow
the use of just the FT-736, 144MHz for the UTM 1200 and then receive on
the 70cm side.
73,
Jerry

Raul,
Even cheaper myself, I use the Fox Delta ST-1 on my G-5400B with great
results. I have the serial version but you can get it with USB too, or
use a USB to serial converter I imagine.

Bob, do you really mean a CubeSat or any picosat?
Recent CubeSat Spec changes have increase mass to 1.333kg/cube or 4kg for a
triple cube which could play nicely into your plans to giving you more water
to zap when in orbit.
http://cubesat.atl.calpoly.edu/media/CDS_rev12.pdf
You have indeed taken on a big challenge of not only the propulsion of a
CubeSat but also stabilizing and orienting it for each burn.
Please keep us posted on developments.

FWIW, Drew and I ran two DJ-G7's in full duplex mode into a comms tests set,
one was Drew's very early model and mine was a more recent model. We also
took the opportunity to test a TH-D7.
We ran the tests using AO-51's uplink and downlink frequencies. Drew has the
actual figures, but as I remember it they were like this:
Early DJ-G7 15dB desense
Later DJ-G7 5dB desense
TH-D7 1dB desense
The test involved adjusting receive signal power until we had a 12dB SINAD
measurement, first without transmitting then while holding the radio's PTT.

Subject: [amsat-bb] Alinco DJ-G7T programming cable
Hi,
Sometime back, while my rig was on back order, I asked if anyone had used
Icom programming cables with it. My rig finally arrived, as did shortly
thereafter new firmware and most recently a memory cloning program. With
that, I have been able to test both the Icom OPC-478 and the RT Systems
CT-29A cables. (Both need a stereo 3.5 mm to 2.5 mm adapter, plus the
EDS-10 adapter which breaks out the Alinco connector to separate microphone
and earphone connectors.) In both cases, I have found that they work
perfectly for both memory management and firmware upgrade. If you already
have a similar cable, you can probably get by with a $4 adapter from RS
rather than a new $55 cable.
Unfortunately, the DJ-G7T is not so far proving to be an adequate satellite
rig, but that is another issue.
