Hello Rupert.
Unless you have paid 178.75 dollars, which is the price to ship to Europe
by UPS, then I suspect you will not receive the arrow antenna.
You need the lower paypal link, not the top one.
Thanks

Hi All,

I've now ordered an Arrow antenna (144 / 430) beam from Antenna
Warehouse (www.antennawarehouse.com) . I've sent a PayPal order
to them for $139. I need to get in touch with them to confirm receipt of
the order and that they are happy to ship to the UK.
I've tried the advertise phone number from their website...no reply and

Hello All,
First of all many thanks for the help from Mark, Matt, and Henk. This
bulletin board is certainly a great resource!
Update:
Today I took my TS-2000X around to another hams place and he fitted a
board similar to the one he fitted in his radio in the 1296MHz section .
The radio is now producing very good quality SSB :-)
After we installed a 70cm and a 23cm antennas on his tower, we decided
to take a look at the PLL/VCO PCB board in my radio. There was no
noticeable long component leads or soldering that needed attention so it
was replaced unmodified. Taking Henks advice I, where possible, rerouted
all the internal coaxes on the board and the boards adjacent to it so
that the coaxes passed between the components differently. Of interest
one coax did a semicircle as it went through an opening near the front
of the radio of a PCB compartment and then went into the other PCB
compartment via its similar opening. This semicircle had a ribbon cable
going through the middle of it. There was a spare grove between the two
PCB compartments for a coax to go, so I placed this coax in the grove.
The radio was then assembled and tested. HEY PRESTO the problem was GONE
:-) .
I have done this fix a only few hours ago now and so far the problem has
not returned..... Fingers crossed!!
Henk, looks as if your fix has worked for me too!!! Full marks.
If it did not work I would have done as Mark suggested and do an
firmware update next. (I have the bdEF version which initially caused me
issues while I tried to load it into the radio).
Best wishes to everyone on the bulletin board.

You can put the cap at the control box but if you want to take the rotator
apart.
1. Turn it upside down and unscrew the 4 screws that hold the ball bearing
racier.
2. Turn it right side up set it on the desk holding the bearing ring in
place
3. With the unit on the desk slide the bearing ring down and lift the
rotator out of the bearing racier. Be careful not to lift the top of the
rotator off the body of the rotator
4. Turn the rotator upside down and set it on the desk.
5. Lift the body of the rotator off the top of the rotator.
If you get the sequence wrong the ball bearings' will fall out no big deal
just capture the all the bearings and put them back in the racier.
Call if I have confused you

Hello Roberto,
In the sub folder "Kenwood" in the SatPC32 program folder you will find a
schematic (IF-232c.gif) that shows the pin numbering and wiring between the
TS-790's CAT connector (ACC1) and the Kenwood IF-232c and between the
IF-232c and the PC's DB9/DB25 serial port.
I had to disconnect the CTS and RTS lines between the interface and PC to
get CAT steering working. Please read the "Hints(Radio) .... Kenwood Users",
sect. B for detailed hints.
The file can be opened from the SatPC32 menu "?".
Also, I have a homemade CAT interface (cheap and easy to build). You will
find the schematic
in the sub folder "Kenwood" in the SatPC32 program folder (TS790Cat.gif). It
works flawlessly.

It's likely that your debit card has either the Visa or Mastercard symbol on
it. The vast majority do.
Credit card systems on line will happily accept it.
The alternative is to join Amsat-UK.

Hey everyone,
?
The QRP Amateur Radio Club International (QRP ARCI) has added satellite
endorsements to many of its awards, which are available to all amateurs.
?
Please visit the QRP ARCI Web site - http://www.qrparci.org/- and click on
the Awards tab down the left side of the home page to see the various awards
the group offers, and to get the guidelines for each award.
?
I?m confident that many readers/posters here (especially those of you who,
like me, enjoy the challenge of using a handheld station on the FM
satellites and of using low power levels in general) probably can claim the
Grid Square and/or All States awards right away ? or, at least, very soon.
?
Thanks to AMSAT and Bruce for its outstanding awards program, and thanks to
QRP ARCI for giving us QRP addicts some other awards to shoot for with our
satellite operations.
?
73 to all,
?

It's pretty simple. It costs us much more to mail the Journal
internationally than domestically. Do you belong to AMSAT-UK? I pay 25
pound to be a member as opposed to the 15 pound you (would) pay.
You can pay dues with Paypal or by counter check in US funds in addition
to credit, debit, or regular check, and you can do it on the phone with
Martha, via post, or email in addition to online.

You can put the cap at the control box but if you want to take the rotator
apart.
1. Turn it upside down and unscrew the 4 screws that hold the ball bearing
racier.
2. Turn it right side up set it on the desk holding the bearing ring in
place
3. With the unit on the desk slide the bearing ring down and lift the
rotator out of the bearing racier. Be careful not to lift the top of the
rotator off the body of the rotator
4. Turn the rotator upside down and set it on the desk.
5. Lift the body of the rotator off the top of the rotator.
If you get the sequence wrong the ball bearings' will fall out no big deal
just capture the all the bearings and put them back in the racier.

I'm about to disassemble a Yaesu G5550 Azimuth Rotor to replace the
Starting Capacitor. Has anybody done this and can give any
suggestions? I'm concerned about taking it apart and a million pieces
falling out
Thanks
- Paul

Very impressive by Mr. Van Wyk. I wish they had asked me to be an

Hi Paul,
If the Starting Capacitor of your Yaesu G5500 Azimuth Rotor is not
shorted out but it only loosed capacity and it only looses torque and
some time stops I suggest you do not dissamble the Rotor.
Simply connect a 100 uF 50 Volt AC unpolarized electrolitic capacitor
across terminals A4 and A5 on the rear screws of your control box.
>From the electrical point of view it is the same to dissamble the Rotor
and put the capacitor inside of it.
If you don't own an AC electrolitic capacitor built it by your self
following the schematic diagram belove:
C1 C2
- + + -
|--------) |------|------| (--------|
A4 ------| | |------- A5
|-------|>|------|------|<|--------|
D1 D2
where:
C1 and C2 are 100 uF 100 volt DC capacitors
D1 and D2 are any diode like 1N4007
