Hi, thank you very much for the clarification. I asked about 96kbps
because I thought it was a new mode, compared to the original specs of
the AO-51, but if it is only 9600 bps, then I am much relieved. Of
course I am ok with referring to this as a 9k6 and 9.6K, so if someone
used 9.6kbps and the "decimal" was dropped, that is perhaps how the
incorrect nomenclature came into usage.
However, to continue that thought, the GMSK modem onboard the AO-51 is
capable I think of many higher baudrates. Is there a definitive list
of modulation/data rates that have been used so far ? From the
published AMSAT Journal articles that I have on hand, the baud rate
possible is 300 bps to 56 kbps.
Any suggestions ?

We have tried up to 38k4 on AO-51. There are currently only a small handful
of users with this capability, so it is not often used.

Hi to all
I have a Kenwood ts2000 but i can not reveive 1k2 or 9k6 bauds in the main
receiver i tried all configurations from the manual with no sucess (in sub
receiver it works ok).
So in this case how can i work digital sat?s?
Any one have this problem or it?s like this ?

Putting words in Bob's mouth (correct me if I misunderstand):
I believe he intends to mount the G5400 with the azimuth part of the
rotor holding a mast that the 6m antenna is attached to the top, and
atrtach the elevation part of the rotor just above the tower to
support his satellite antennas. The separation being sufficient so
that when the satellite antennas are elevated they clear below the 6m
antenna. BTW my satellite array on a B5400 is essentially the same
as Bob's and it survived 5-6 years in the wind about 12-foot above
the roof (~25 feet above ground). I have yet to re-install them at
our new house on a ten-foot tower.
http://www.kl7uw.com/sat.htm
My concerns would be two:
1. Is the azimuth part of the B5400 strong enough to support
approximately 12-feet of mast with a 6m beam on top (a solution would
be to mount the rotor below the tower top and use a thrust bearing
(my Tower #2, raised this last Thanksgiving, is constructed this way
using a Ham-IV rotor ten-foot below the tower top having a TB3 thrust
bearing and ten more feet extending above the tower. On this I have
a 3-elem Triband HF beam, two stacked 3-elem 6m beams, a 432 and two
222 eleven element beams. The mast is twenty feet of 1-1/2 inch ID
sched-80 steel (very heavy).
2. Will the 6m beam interfere with the beam pattern of the satellite
antennas when they are elevated?
Note that my two 6m beams are stacked with one 5-foot above the HF
beam and the other 5-foot below the HF beam, so one could ask whether
the HF beam will interfere with the 6m antennas? I'll have to let
you know as one is not yet connected to coax.

How would you mount the 6M beam ABOVE the elevation rotor?
There is no mast clamp on top of, and a vertical mast does not pass thru,
the elevation rotor....

Hi Gus,
I do not have the answer on which distance to apply really.
Just to share my experience:
- here at home I never have had any issue with de-sensing
and I do not use any filter or trick. with any of the
radios (ts2000, ft817, thd7) it all works fine.
- field operations:
I use no desensing filters either.
145mhz antenna straight to the ft817
435mhz antenna straight to the thd7
antennas clambed together on eachother
... well, in this set-up it makes a BIG difference
how I align the antennas. Moving one forward 1 cm does
make a big difference. (sliding the booms across eachother)
so not the boom2boom but element to element distance.
but that is applicable for arrow like setup, not for
permanent mounted constructions.
Mmm, I am afraid this information doesnt help you at all :-)
Henk

hi all, January 21, 2009
I am assembling my first satellite station and have a question about the
preamp bypass relays.
Background:
> The rig is the TS2000 and I want the flexibility to use the full RF
range for 2m (100w) and 70cm (50w). No RF out amp at this time. I
realize I may never need the upper RF power limits, but I wanted to
build in the option from the start.
> I have a modest antenna system with a pair of omni's each on their
own coax feed. Each will have its own mast mount preamp.
> The rig is capable of inserting a sequencing Tx delay.
> The preamp bypass relays I have on hand are: AXICOM D2n
(V23105-A5003-A201), 12vdc coil. I needed and found a relay with a low
coil current (13mA) to be within the rigs trigger abilities (20mA max).
So far so good.
>> The relays specs. state: "switching and continuous current = 3A" and
"maximum switching capacity = 60w, 125VA".
The question(s):
Q1... Does this stated 60w power limit for the contacts also imply a 60w
limit for the RF level I wish to run through it? Again, the rig limits
out at 50w on 70cm so this is not the issue, but it (the rig) can go to
100w on 2m. In other words, I am unclear how the power limits of the
contacts may or may not change as one goes from DC to 60Hz to 144 MHz to
440 MHz?
Q2... I have been reading about relays that are specifically designed to
handle RF, yet I see many operators that seem to use more "generic"
relays for this purpose. What is the requirement here with respect to
frequency? This station is not intended to go to GHz.
In conclusion:
_Is the above sited relay suited for this purpose?_ Are there
constraints or design considerations? If the answer is "nope, wont
work", then what (and who) offers a not very expensive solution? I
really would like to stay under my rig's 20mA limit for the coil current
(and therefore maintain the sequencing ability).
And as a final comment, the general consensus seems to be to go with a
hardwired relay system and avoid the RF switched types. This last is
why I am pursuing this path.
thanks for the advice! ac0z, .paul

Hi Dave,
I think you need the UX-14 plugin replacement rather than just the LCU-3
for these rigs, as they use the older CI-IV protocol, rather than CI-V
See http://www.hosenose.com/detail.asp?product_id=UX-14PX
