Skipp, Interesting you should mention the "blanketing contour" effect..
My 6m machine (51.4 in) was receiving on channel IX from a VHF jamming vehicle over at the Marine Corps Artillery Training Range about 3km's away. I got tired of the in-bound mess, and stuffed 700W of RTTY "cease and desist" into a phased stacked 6m array (14dB of gain), and shot the message back to them about a dozen times. (Jeez I love the results of my hacked SB-200 on 6m, which BTW is quite clean... just waaay loud!) Seems they must have had an "old-timer" on the training staff (no newbie would recognize RTTY)... the interference magically disappeared! I have also been known to do the same in my mobile when an earthquake on wheels gets just a little annoying <grin!>. When things in my vehicle start buzzing and rattling, it is just too darn loud!! BTW.. it works very well on electric guitar amps as well!! 73 Mike Perryman www.k5jmp.us -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] Behalf Of skipp025 Sent: Thursday, April 20, 2006 12:02 PM To: [email protected] Subject: [Repeater-Builder] Amplifiers at Flea Markets Hey now..! Don't pick on the Black-Cat Amplifiers... I use one to shut down my neighbor playing his home stereo too loud. The darn thing will even hose up his Auto Stereo pretty well. A nice low frequency semi square wave signal will get him to shut down his mega-stereos in less than 30 sec typical. "Nelly" and "50-Cent" can't compete with "RTTY-Signal" into a JB-150 (on ten meters of course) to the folks here in the hood. :-) s.
