Topband: Summary pf replies re: Hooking beverages to IC-746

[Edwin Steeble]

I got about a dozen replies. Here are the pertinent ones:

1) If it is like most Icom's, there is a loop in the receive line between
the T/R switch and the RX input on the radio.  Simply remove the jumper
and get either a 2 - 3 - or 5 position cable tv antenna switchbox from
Radio Shack and put inline. You can then add several other receive
antennas to be switched.  One secret hint -- the 5 position switch can
combine 2 or more RX antenna sources to one output!

Works great!  I use the phono plugs for the RF cables and use F to Phono
adapters.  This way it is easy to use RG8-X for the junpers. (OR RG58 -
ugggh!!) 

**My comment. I did that with my IC-735 but the IC-746 doesn't have the
loop in the receiving line. I was hoping someone had gone inside the case
and found a neat way to do this on the IC-746.

from #1 a PS) Also, I put an ICE RX overload protector in the switch output
line.

2) I use the PTT line for keying the 12 volt dc relays.  There are a 
number of relays in use - some for selecting antennas, some for selecting 
directions (on lazy v antennas) and some for selecting the EWE rx antennas or 
directions. 

** For those who misunderstood my question, I know how to switch the EWEs.
The method I use is a manual switch inside the shack.  What I was looking
for was insight into whether or not ICOM had a loop in the receive line
between the receiver and the TR switch. 

** And for those who asked about the IC-746, my 160m and 80m antennas are
down. I had to take out a dead tree and it fell accoss where the radials
were. The 160m elevated inv L and 1/4 wave elevated 80m vertical will be up
for the fall season. I hope to get on 10, 15, and 20 for the IARU contest
this weekend and try out the rig then.
