A little hard to tell what you mean by "port". Do you mean the RCS-10 port or a 
port on the transceiever ?

I understand you to mean that when you bypass the RSC-10 antenna switch and 
feed the inverted-L directly,  the inverted-L works OK on 160 meters ?

I mentioned back on 12/31 that RF at 1.8 Mhz may be getting into the control 
lines and causing the switch to malfunction (hot switch) under load.

A suggestion would be to look for RF on the control lines at the shack when 
transmitting on 160 meters. Go to the lowest power the transciever can deliver 
that doesn't hurt the transceiever (if possible).

Is the control line connected directly to the transceiever ?
This could explain why the transceiever is behaving erratically when operting 
at 160 meters with the switch. RF is getting into the control lines and in the 
transceiever through the control port.
Are you getting a microporcessor reset at the transceiver when the 1 minute 
blanking occurs ?

Ok , I am having a real problem here that I haven't been able to solve yet.

I have an inverted L out at the tower that is about 160' long , 70ft vertical 
the rest sort of horiz , slopes down.... I have one run of RG213 to the RCS-10 
remote antenna switch which is at the tower , it was very close to the L , so i 
moved it so that it is now about 4 ft away from the L, I also grounded it. what 
is happening is that when i transmit , even 1 dit at about 10 watts something 
happens out at the switch , the radio goes silent , then after a minute or two 
it usually starts to come back. it only affects the port that the L is attached 
to , my Windom is on port 2 and it works fine , so it isnt the radio , the L 
also works just fine on other bands , I replaced 2 PL-259's and changed the 
coax that goes from the switch to the L , I do not know what else to do at this 
point other than at night when i want to use 160 go out to the tower and 
connect the feedline directly to the L. It happens no matter what port i have 
the L connected to...

any ideas ?

Dan
