Hi,

I finally got the 10M beacon up and running. Plans call for running it 24/7, 
though with NO real-estate for antennas, all 7 antennas (Butternut HF-2V, 
Alpha Delta DX-EE, Inverted Vee's for 15 & 10M, two LF active whips and the 
new 10M antenna) antennas are unavoidably in closer proximity to each other 
than I would prefer (all mounted over my mobile home roof/awnings) there 
'may' be times I need to shut the beacon down to prevent receiver desensing 
while DXing.

So far all these antennas being close to each other has worked well, but 
then I've not tried running "multi" (multiple stations) in any contests etc. 
Depending on which antenna/band is in use I can hear the receiver "puffing" 
in time to the beacon keying 8^(  The two active whips for LF seem to be 
especially vulnerable 8^(  That means that I may have to shut the beacon 
down when NDB chasing. . .

Specifics.
1.  Frequency: 28.248MCS.  May change that later if I receive reports that 
another beacon and I are QRMing each other.
2.  RF Power: 7 Watts from "gutted" JC Penny 40 Channel CB.
3.  Antenna: Roof mounted 1/4 wave groundplane over approximately 1200 Sq/ft 
of sheet-metal roof/awning.  1.2/1 SWR at the operating frequency and under 
1.5/1 between 28.0 and 29.0 MCs.  Under 2.0/1 at 29.7MCs!
4.  Keyer:  Old NEC laptop computer running DOS.
