**NOTE--For WSJT contacts, I expect to receive your RRR and/or 73 before I will consider the contact valid. 

******  NEW AWARD:  6 Meters VUCC #2247, as of December 2 2014 *******************

LOTW access  is  working. I am now using the easy program "ACLOG" to create the upload files, so please be patient.  I intend to send all logged QSOs  to LOTW.

Please email me if you wish to use EQSL to exchange "cards".

Current project: 70 CM Small station EME. Arizona is normally restricted to only 50 watts on 70 CM, so I have received approval from the FCC (and the military frequency coordinator) for a power increase to 500 watts and up to 20 dBi antenna gain. Antennas for EME are two M Squared 12 element yagis on an az/el/polarity mount.  The polarity adjustment is made by manually rotating the rear-mounted antennas via bushings on the cross-boom. The counterweight on the left side of the crossboom is a plastic bucket full of rocks!

70 CM EME antennas

 

-----------------------------------------------------------------------------------------------

Existing 70 cm equpment: WA2ODO 70 CM preamp, and also a G4DDK LNA70 two-stage preamp.

Tropo Rig1: Yaesu FT857, and 100 Watt Klitzing Brick amp for tropo, 18 element M2 Yagi

EME Rig2: and 500Watt W6PQL LDMOS amp for EME. Ant:  Two M2 432-12 Yagis,for EME with AZ/EL rotators and manual polarity rotation. Presently running amplifier at 400Watts Key Down, and 325W at the feed due to lossy coax.

--------------------------------------------------------------------------------------------------

6M equipment:  FT-817 rig, driving a Larcan TV amplifier for easy 400Watts key down  into lossy RG-8 coax. 5 element beam at 33 ft.

------------------------------------------------------------------------------------------------

2M equipment: FT-817 rig, driving a good 'ol "Fire Bottle" AM6155 Tube amplifier at 300W key-down. 13 Element K1FO beam at 33 ft. LNA in the shack.

Now retired electronics engineer, first licenced as KB7TRZ in 1993. Pre-retirement career projects include electronic design for several of the Mars missions, including the super-successful Mars PathFinder digital Camera from 1997.

The Pyramid picture on QRZ was taken on our trip to Egypt in April 2009

I am constantly chasing grid squares, and I hope to get the VUCC award  for 2 Meters someday!

A channel 3 Canadian Larcan TV transmitter amplfier has been modified for 50 MHz and is now on the air for tropo and meteor scatter. It runs from a 5Watt FT-817 exciter. 5W input to amplifier => up to 750 Watts key down.

I am active and interested in portable microwave operation, (10 GHz for roving and mountain-topping. 2.3 GHz now operational with 1 watt, barbecue grill antenna only for now).

High power 70 Cm and 2.3 Ghz gear (and soon 2.8 meter dish) is in work, for future use and 2.3 Ghz QRP equipment is now complete, with loop yagi/barbeque grill now operational (QRP). First contact made with W7JM, across the Tucson valley.

The 2.8 Meter dish is on its mount, counterweights and motor drive are in-work.

 

*** UPDATE: I an re-designing the dish mount, changing it from Polar mount to AZ-El.  This will make counterbalancing easier, with less stress on the motor/gearbox parts.   ************

Dish feeds for 13 cm and 23 cm are assembled, and feed mountings are yet to be finalized.

A dish feed for 3400 MHz (9 cm) is planned, using a down-sized VE4MA 23 cm feed, scaled by Dave Robinson WW2R. A transverter kit has been received from Graham Burns VK3XDK  of Australia.

10 Ghz (3 cm) portable operation has been activated for several years during the 10 GHz contests.  Best SSB DX was 325 miles from Mt. Lemmon Arizona (DM42ok) to Mt. Laguna California (DM12), running 0.6 Watts to an 18 inch offset-fed dish.

I am constantly experimenting with antennas and modifiying old vhf and microwave gear.

I will operate SSB, PSK, Olivia, WSJT and the other digital modes on any band. CW skills are very poor, but I am motivated to improve because many EME contacts are available via CW-only.

Best bands are: 6m and 2M. 70 cm EME and 2 meter EME are now operational , depending upon power line noise and other QRM.

QSL INFO: Direct is best (SASE not required for N. America QSL contacts) , also LOTW and eqsl.cc ( I have eQSL AG- authenticity guaranteed).

LOTW access  is now working.  I am using ACLOG to create the upload files, so please be patient.  I intend to send all logged QSOs  to LOTW.
