I recall reading about a speaker that you can plug into any radio so you
can keep the squelch open all the time and a DSP will only let audio with
It was intended to be used to listen for beacons on satellites as well as
listen for band openings without driving the XYL crazy with static being
blasted through the house.
Does anyone else recall this speaker (or inline module)? I've searched
and found DSPs that will attenuate white noise, but I haven't seen any
that turn off the speaker completely in the presence of white noise alone.

I few days ago now, ANDE-1 and RAFT were
simultaneously visible from my QTH, and everyone
else's too, I imagine.
Since both satellites Tx and Rx on 145.825 MHz, I
wondered whether a dual hop is possible. However,
it seems that the satellites are configured to
prevent this. I wonder if there are any plans to
try a dual hop - perhaps later when the satellites
are near the end of their lives.
I presume too, that when they are in sight of each
other, RAFT would been keeping ANDE awake. Is this

one per transponder on a single channel fm satellite. as two
transponders are active, you can make one contact on v/u and one on l/u.

Shouldn't that read L/S antennas ?

For Field Day this year AO-51 will be in a dual repeater mode, with the
Uplink 1268.700 FM, no PL tone
Downlink 435.150 FM
Uplink 145.920 FM, no PL tone
Downlink 435.300 FM
As a reminder, both the AMSAT and now ARRL Field Day rules state only one
completed QSO per FM repeater satellite. Please adhere to this rule so that
others may have an opportunity to make a QSO. Also, all stations are asked
to please only transmit when they can hear the satellite, and please use
full duplex (with headphones) as a courtesy to the other users. Those
stations planning on using circularly polarized antennas please remember the
435.150 downlink is left hand circular polarization (LHCP), and the 435.300
downlink is right hand circular polarization (RHCP). Stay tuned to AMSAT ANS
bulletins or the AO-51 News page

AMSAT VP Operations
Was just wondering if there is anyone out there with any experience setting up a D700 for Packet operation. I do not seem to be able to get my terminal program to speak to the TNC. I can't even get a cmd prompt or any semblance of a connection. It seems to be physically connected fine but still no luck. I have set the baud rate for the port to match the TNC (9600) but am not having any luck. I am just using HyperTerminal. Any ideas?
