Sounds like your antenna has been isolated from your receiver. Check or
replace the cable between the receiver and the duplexer. If that doesn't fix
the problem, you may have a mis-tuned duplexer or a blown pre-amp if you are
using one. RF issues are the same in digital as they are in
On two meters and 440, we have programs in use called D-Chat and
D-Rats that send data back and forth between users, either simplex or
through a repeater connected to the gateway. There is no high speed
data capability on two meters and 440 because high speed requires more
bandwidth than we have
A good topic for discussion. Maybe we could designate a reflector
channel or two for testing interconnections between linking systems
(Echolink and IRLP). Much like the Western reflector (IRLP) uses 9258
for connecting to an Echolink conference bridge, we could agree that
one of the channels on

The digital band plan being tested currently puts the D-Star outputs
between 144.9 and 145.1 and the inputs 400 kHz down. This keeps
everything in the spectrum designated by the FCC for repeater use.
Since alternate input channels are inputs for analog repeaters, only 9
new channels
Yes, we tuned a Celwave 6 can mobile UHF duplexer to 100 db using an
IFR and and a return loss bridge. It's the best one I've seen, as most
are in the 75 to 85 db range.
When Telewave recently retuned our 6 can full sized 2 meter duplexer
for our new 400 kHz split, they were happy to hear that it
