Hello all,
Every time I send an email to amsat-bb@?????.???? I'm getting a spam
email reply from erikakatos2@?????.??? trying to bait me to into going
to another website.
Looks like it did come from a yahoo.com email server:

(pobox is my email provider, of course)
Could AMSAT IT check the subscription list and see what's going on?
Thanks,

The Kantronics 9612 works fine on FS-3, however, the Signalink will not pass
9k6 data.

I want to be able to work Falconsat-3. It is a store and forward. I have a
Icom 910h. To use 9600bd I have a Kantronics KPC-9612+ Has anyone used this
to do 9600bd pacsats?
Or
Has anyone used Icom 910h to Signalink using the two data ports in the back
which are for 9600bd?

Just wondering what SW (or HW) modems others are using for GMSK encoded

Hi Chris,
You might try gr-satellites. Worth learning some Linux and GNU Radio.

Actually....a current Signalink will work on FS-3 at 9600, I did it this
weekend (with a IC-9100) :)? And it will copy DUV telem from the Fox
family.? I wouldn't call performance in either case to be "stellar" but
it does work...wouldn't be my first recommendation, but it works...

Good to know! The previous ones I know were problematic for both 9k6 and DUV.

I'm purchased 2m and 432 preamps for my satellite antenna system and both
will require external bias-tees for power. Looking around on both US and
UK/EU websites I've found bias-tees that cost almost as much or more than
the preamps did. The inexpensive devices I've found are receive-only and
meant for SRD users.
Does anyone know of a source of bias-tees that cost less than $100.00 each,
have decent specs on 2m and 432 and can withstand a transmit power of 50 or
100 watts. (Yes, I know I don't need to run 50 or 100 watts for satellite
work but I don't want devices that will fail the first time I accidentally?
transmit "QRO".
Thanks

If you have the time to work with surface mount parts, Marki Microwave
sells some SMT bias Tee's for around $50. I didn't see a spec for max RF
level on their web site but it might be worth looking into. I bought a few
of them one time to protect the ports of my VNA by grounding the DC
input terminal. They've worked very well.

Thanks.
I found the spec sheet and it lists 1 watt as the maximum power handling
capability.

If you have the time to work with surface mount parts, Marki Microwave sells
some SMT bias Tee's for around $50. I didn't see a spec for max RF level on
their web site but it might be worth looking into. I bought a few of them
one time to protect the ports of my VNA by grounding the DC input terminal.
They've worked very well.

I'm purchased 2m and 432 preamps for my satellite antenna system and both
will require external bias-tees for power. Looking around on both US and
UK/EU websites I've found bias-tees that cost almost as much or more than
the preamps did. The inexpensive devices I've found are receive-only and
meant for SRD users.
Does anyone know of a source of bias-tees that cost less than $100.00 each,
have decent specs on 2m and 432 and can withstand a transmit power of 50 or
100 watts. (Yes, I know I don't need to run 50 or 100 watts for satellite
work but I don't want devices that will fail the first time I accidentally
transmit "QRO".
Thanks
