Subject: C31XRs in SO2R ???
Author: WD4K <WD4K_1@Bellsouth.net>

Hi Jack, I have had two C31's stacked for the past couple of years but not
using individual feeds. I am this week stacking three C31's, Mag340N and
180B. I am set up for SO2R and after much investigation I can find NO ONE
who is using the individual feeds and running legal power SO2R or otherwise.
Maybe someone is but they sure never responded to any of my requests for
info. Also I can only say that some say it should work but no one will
guarantee it. I personally took the route of stacking three, using a dual
feedline(WX0B) on one antenna and other than the WX0B stackmatch, I use
exclusively the Top Ten switching system. The matrix is wired using the abss
relays, sixway boxes, Ice 419A's all preceeded by six ICE 348's and four
303's all on a dual plate/copper buss setup. I just did not believe that it
would work at legal without some type of interaction, and sure did not want
to do all the work and expense only to find out that it doesn't. Not a good
gamble for me. I guess it could work on low power but I would not want to
bet on more than that. If you think it will work and want to try it, it
certainly wouldn't hurt anything and would be great to have. Good luck and
let us know what you find out. Tommy WD4K

Subject: [Force 12 Talk] C31XRs in SO2R ???


All,

I am considering re-wiring my pair of C31XRs to the individual band feedline
arrangement to facilitate SO2R contest operation. The present plan would
be to use the W3NQN filters with a WX0B switching setup.

My concern is that the close proximity of the driven elements might be more
than the filters could deal with effectively. Has anyone out there tried
this or a similar arrangement?

I would appreciate hearing about anyone's experiences, good or bad, with
C31XRs in this sort of setup.

Thanks.
