Thanks to all that responded. The problem the F connector is spinning on the
block and I might have broken termini connection. I am looking for the
actual wiring diagram at the driven element so I can check it with a ohm
meter.
Does anyone know how it is connected?

With all the talk about tilting a Yagi 15 degrees above the horizon and
using a rotor in azimuth only, I have a question. Since every Yagi I have
includes mounting hardware to mount the antenna at a 90 degree angle to the
mast, how do you tilt it 15 degrees? Do you put a bend in the mast pipe?
Can you purchase hardware to allow the Yagi to tilt relative to the mast?
Maybe everyone knows a simple answer but I will admit I do not.

Nick,
I had something similar happen, and just popped open the terminal block.
Nothing tricky, and the
problem was obvious "by inspection."
Good luck,

or if you don't have surrounding objects blocking the horizon mout the
antenna low like at ten feet, then youd have a elevated angle and ground
gain too!

Thanks for all the input regarding the FM 'repeater' on the ISS. Further
research into the issues has enlightened me on the machinations of
getting things done on the ISS and the complicated processes of working
with such varied national interests. It is obviously way above my pay
grade and with these comments I sadly end the quest with a feeling of
not going anywhere.
The Kenwood TM-D700 portion of the Phase 2 Hardware system is apparently
overheating. Possibly because of a lack of airflow over the heat
sinks. Possibly because when it is made available, the duty cycle rises
to near 100% and the unit consumes too much power from the ISS power
budget. Since the other parts of the Phase 2 system are fulfilling the
needs of the ISS and NASA agenda, there are no resources available to
correct the problems with the TM-D700. Indeed, replacing it with a
linear transponder of equal bandwidth and much reduced power consumption
may be a much better solution but there do not appear to be any benefits
to the ARISS program to drive the solution. There was a mention in the
paper produced circa 2002-3 of a third phase of the ARISS hardware
system to be mounted outside but no mention of such a program since then
has been located.
Should others want to pursue a program of getting a linear transponder
mounted on the outside of the ISS, I wish you luck and refer you to the
document;
"Amateur Radio on the International Space Station - Phase 2 Hardware
System" by Frank H. Bauer, KA3HDO, Lou McFadin, W5DID, Bob Bruniga,
WB4APR, and Hiroto Watarikawa. Sergej Samburov, RV3DR was also listed
but this call sign now returns as belonging to Energia in Russia. The
document was found at http://www.ariss-eu.org/phase_2_document.pdf
on the internet. Frank is a new Amsat VP in this area, Bob is a
participant in this list and Lou is still around too I think. Maybe one
or all of them can help.

Notwithstanding the difficulties and complexities of getting something
up to and installed on the ISS, why would we want to put an obsolete
radio up there anyway?
Seems to me that a TM-D710 would be a much better replacement for the
D700. For one thing, it has a built in cooling fan which should take
care of the cooling concerns. It's obviously not a linear transponder,
but then most hams don't have the equipment to use one anyway while most
of us have VHF and UHF FM equipment.
Coupled with a laptop, it could be used for WL2K comms, APRS and
straight up packet in addition to plain old voice comms.

Hi, I'm baffled as to why you mention the ISS power budget. Do you have any
references, ARISS or elsewhere, to confirm that the ISS power budget has
ever been raised as an issue ? The one thing the ISS appears to have in
abundance is Solar Power.
The equipment to be installed on the ISS for the HAM-TV project will consume
far more power than the Kenwood TM-D700 ever did.
The KuPS power supply that was built to power the HAM-TV transmitter was
designed to supply power to up to three separate payloads.
