Updates

Middlesboro -

443.950 is off the air until I can replace the antenna.  It appears to have slowly degraded over the past 2 years.  The desense issue has now been eliminated up to the jumper or the repeater antenna.  Info gleaned from the web would indicate that the Diamond 718 antennas can't handle the mountaintop locations for - of all reasons - heavy moisture condensation at altitude.  Go figure.

Caryville -

I have decided to go ahead and coordinate the 444.675 (+ offset, 100.0 Tone)  Seems like much ado over nothing considering it's low profile and lack of coverage, but I might as well.

It is IRLP connected and is parked on the East Coast Reflector 9050 mostly during the day.  At night, it may end up on either the 9109 Alaska Channel or 9070 Alaska Reflector.  Or on 9050.  Feel free to use it.
73 disconnects while simply inputting the IRLP node or reflector number will connect.
Just be sure to wait 30=45 seconds before transmitting when you first arrive so as not to inadvertently interrupt a QSO.  If you connect up with something just disconnect after you are through.

Allstar Node 41538 is running on 146.460 (100.0 Tone.)  I am planning to mount the antenna about 20 feet higher and go with a higher gain antenna - but not too high a gain - we are in the mountains, after all. This node may or may not be connected to an IRLP bridge, another Allstar or Echolink node, or simply idle.  *70 will give you the node status.  If it is in repeat mode, you're set.  If not, *73 will disconnect all.  *3XXXX (xxxx=allstar node number) will connect you to the node number you input.  If you want to use Echolink, shoot me an email.  It's a bit more tricky.

Future plans -

Once 950 is back on and working, I will connect it to the Allstar Linking Network.  Why...?  Because we can!!!
