CQ Zone 3, ITU Zone 6, ARRL Section "San Diego," Age 43
VILLAGE OF LA JOLLA - A San Diego Community (QTH is on the point, far righthand side of picture)
We also have skiing in the local mountains outside of San Diego. WORK DX, Surf and Snow Ski same day!
Rancho La Jolla Antenna Farm consists of the following: 75m two element close spaced in phase fed end fire "Grounded Loop Array" with Top Loading at 45ft. 1.6dB gain over single 1/4 wave vertical. 4dB front to side ratio. Same antenna also used as a 40m full wave "Grounded Loop Array" matched easily with a 75 ohm quarter wave coaxial stub and then 50 ohm coax to shack. Antenna relay ungrounds the Loop at 1.830 MHz resonance and then is used as a 160m Inverted U.
Performance of array installation is RECORDED below for 160m and 75m at various locations around the world.
Additional Receive: 80m/160m Receive Loop for diversity reception by KC2TX/W7AE with Variable Gain 80m/160m Pre-Amp by KD9SV. It has a very high adjustable Q and presently is tuned for the 75m DX window and 1.830MHz (covers CW Portion and 1.843 to 1.860MHz SSB). Works well but I have found that I need to keep as far away from TX antenna as possible for various GOOD reasons. It senses the TX antenna for one, meaning noise floor pickup-NO BUENO. It is vulnerable to RF for two (you want ground on transmit or risk damaging your expensive transceiver's receive antenna input). For those local to the area, it has outstanding groundwave directionality on AM radio and is ultra quiet. It plays more Omnidirectional at night so it is best used to null any local noise to achieve the lowest noise floor possible. During tuning tests, it could hear FB the VERY low power Orange County Toll Roads broadcast on 1.680 MHz in middle of day nearly 80 miles away, which demonstrates great sensitivity and rejection of local ground noise. Just static and buzz on TX antenna - What Toll Roads broadcast? KFI 640AM in Los Angeles was +20dB pointed at it, and 57 when pointed away when tuned to that portion of band. Receive Loop does not defeat a beverage or other exotic receive arrays for low angle DX. The 80m/160m Receive Loop has allowed me, however, to confirm MANY local, SEVERAL midrange and more than a few mid angle DX contacts that I could not dig out on the TX antenna due to local ground noise, particularly in the early evening when every noise source imaginable is turned on. The conditions dictate which, TX or Receive Loop, antenna hears best on any given night and at different times. It cannot be predicted. The variability amazes me about the low bands. I love it. VY2ZM (K1ZM) and K3ZM, Low Band 160m Jedi Masters, counseled me that one "CAN NEVER HAVE ENOUGH RECEIVE ANTENNAS ON THE LOW BANDS." They are right. :-)
For those that can hear me, thank you...thank you...thank you.

That's my story, and I'm sticking to it! 160m CW/SSB and 75M SSB DX are my favorite activities. I definitely consider myself a low band fan. I also participate in contests.
Work you on the bands!!!!!

More interesting links....
If you are a low band fan, you might enjoy hearing the European pile-up below on 75m. YES, I SAID 75M!!!
The below link is an accurate representation of our 75M SSB signal into Europe around 0800 UTC from K6AAX/VY2
(PRINCE EDWARD ISLAND, CANADA - IOTA NA-029). This was done from the VY2ZM Contest Station right on the
Atlantic Ocean. Thanks for all the contacts!
VY2ZM CONTEST STATION
Recorded at VY2ZM during the 2011 160m ARRL CW Contest, it is my CW contact with VY2ZM on 160m
from the K6AAX California QTH. :-) TOP BAND!
The "you tube" link below was recorded at A61BK in United Arab Emirates (Thank you, Khalid!). I was at VY2ZM's SUPERSTATION QTH on Prince Edward Island (Canada-link provided) operating 40m SSB and calling CQ DX as K6AAX / VY2 just before the March 2011 ARRL SSB DX CONTEST with 10 Elements pointed at Europe (two 3 element stacked Yagis (highest one at 170ft) and two 2 element stacked Yagis on another tower at 120ft). The pile-up was deafening. I DEFINITELY WAS MAKING SOME NOISE!!!!!!
40m SSB Pile-Up Link
75m SSB QRP DX Mobile Contact with England from Prince Edward Island (Canada) as it happened (M3SGS/M and K6AAX/VY2)
At the time of this contact, I was using a Six FULL SIZE Vertical Array right off the Atlantic Ocean and pointed at Europe from VY2ZM ("THE DEATH RAY")
