Big thumbs down, as the full duplex desenses very badly. Nice radio otherwise,
but stinks for satellite. I bought one of the first hundred, and have kept up
with the firmware updates.

Good morning,
Since putting up the Elk on a rotor (fixed el +- 25 deg), I decided to try
some linear birds.
I have tried FO 29 about 3x but seem to have some issues. I am using TS-2000
in SAT mode with HRD Sat program.
Up: 145.9 LSB
Dn: 435.8 USB
I am clearly able to track the bird with

Okay, but *why*? Why are we so obsessed with squeezing bandwidth down
and down,
It sounds like you when you are hearing your distorted voice it is some
cross-mod from your own radio rather than a downlink signal from the bird. I
assume you are using a diplexer to split the coax from the Elk to 2m and 70cm,
and then running coax to each output on the TS-2000? The diplexer
Or he could just use FM since hardly anyone uses the SSB birds compared to the
other sats.
Although I am sure there are a million reasons not to use FM. even though it
works just fine on the SSB birds. The feedback I got from the FO-29 Control
Team was that SSB was pretty much the rule or
I am clearly able to track the bird with doppler as I can hear the CW beacon
through the entire pass (switching back and forth). I can also TX into the
bird and hear my signal coming back duplex. However, what is coming back is
my voice signal but totally unintelligible. Also, I have heard no
That's a weird one...let us know when u find it!!
Totally clear and full quiet no distortion

There are some very good reasons to NEVER use FM on a linear
transponder, especially FO-29 and AO-7.
Since FM is running a constant carrier, it sucks all the available power
away from other users on the transponder, and makes the transponder run
a full-carrier on the output.
This is VERY hard

Thank you for your responeses, I finalley get a good answer other than just
Stay off the linear birds I knew some of you would get your panties all in a

So it makes sense, thanks for taking the time to explain...

Thanks to all that offered advice...
I just copied the last pass here on the west side (a 20 degree max for me)
and started the rx at 435.895 and eventually with some manual tuning, heard
WB0KFC and a K6 station chatting. I did not get in as I was scrambling about
tuning ! So, it looks like I
I would thank everyone who commented on my question about the diplexer. The
discussion opened up some new thoughts where, had I not read about duplexers

will have everything going ! Thanks again to everyone and I hope to

No, they do not close DVNP after Easter. It is open all year around. There
are a couple of camp grounds closed after mid April that is only due to
the lower attendance. I was there last year well after Easter and walked
