Hi Rick
��� That would explain a lot, I wonder about the 223 port not hearing as
I see quite a few entries on port 3 with very recent times. Maybe it will
be a simple thing like the power switch on the amp..
Interesting thought, if the pre-amp switch in the amp is on and the power
switch is off then maybe the receive is less sensitive. Are the ant lines
switched when the pre amp switch is thrown??
Guess we'll find out when Clayton looks it over..

Well, I hooked up my 220 monitor to the tnc to see who was not talking to
whom.
#coa is talking just fine (and probably listening just fine)
w4mlb-9 is NOT talking on 220. no transmissions. he does not respond to
connect requests from #coa.
If you go into w4mlb-8 and try a C 3:#COA there are no emissions from
mlb switch.
that sucker has gone quiet. BUT not totally. I saw it burp once on 220.
If you look at the monitor list at the end of this, you'll notice ONE
transmission from mlb.
hmmm.
could be that we didn't get the cable hooked back up right after doing the
swr / power check.
Maybe Clayton could do a quck cable check on it.
other than that ..... it also doesn't seem to hear so well, I do notice
#coa on the heard list, but there is no correspondece between actual
transmissions by #coa (as I monitor) and what mlb hears -- mlb seems to
miss a lot.
could be that it IS an RF path problem --- ant to power amp to radio.
i dunno.

220 monitor --- the connect request are from #coa
(2 meter connect to coa1, then C #COA cross connect, then C W4MLB-8)

Hi Rick
I was able to connect to W4MLB ok this afternoon and I agree with
your comments concerning COA. I tried forcing a connect to #coa and when
it timed out looked at the heard list on mlb - no response to the
connect request. I do see node broadcast and node id from #coa, it looks
like they are not hearing anything - unless Bud is able to connect from
his direction. Best thing to do is to let the folks in Cocoa know that
the node in not receiving on 2m and 223mhz. I sent Bud the name of the
contact person in Cocoa. It is in the laptop here - if Bud doesn't have
it handy I will dig it out..

Clayton and I installed the melbourne FPAC switch today.
We installed everything, did SWR and power checks on all antennas, and
did
connection checks.
There are still some problems. Maybe not so big. But here they are.
1) 2 meters. High VSWR on 2. we couldnt' get to the antennas on the
roof
because the door was locked, but the antenna exhibits high VSWR.
>From the site, we can connect right up to my house first off, no
problem.
so power is getting out. Later from home, I was able to do local access
easily, all radios show full bars on lcd, good sig strength.
SO: we need to do some antenna work. Clayton says he has spare ringos,
we
can set up and tune one on the ground and replace the one on the roof of
the
building. The 2 meter ant is the only ant we can easily get to without
climbing so things will work fine they way they are for now, and we will
correct the vswr on 2 soon. but it works well enough as it is now.
2) 220.
Not sure what to think there. power measures 80 watts out, ant vswr is
about 1.5. connecting to #COA was 'flakey' worked sometimes, and
sometimes not.
went home, tried connecting to #COA via switch -- no go. tried
connecting
to COA1 from 2 meters at home, no -go. beacon heard from COA1 though.
Tried another radio, this one did connect to coa1 then cross connect to
#coa. Tried to connect to w4mlb-8 and get failure message. Connect to
w4mlb-8 and check stats -- it sees #coa just fine.
I don't know what to think at this point -- the link to #coa on 220 is
flakey from the switch. and the link to COA1 from 2 meters is flakey
from
here at home. although, his signal strength is very strong.
I tried linking down to vero, stuart, okechobee, etc. and everything
comes
up real fast, no problem.
so we are back to were we were -- local access and 70cm access south is
good.
70cm power is 25 watts, swr is 1.3. seems to be solid.
gotta go back to work now, so that's it for now -- - i'll try some more
testing tonite.
John, try working some stuff up from your end and see what you can see.
cheers
rick
