This amp is an engineering prototype for a 1KW, air-cooled, 1.5-54 mHz SS amplifier using the MRFX1K80H LDMOS device. Over the next few months, the amp and controller will be tested for performance and durability as compared to equivalent liquid-cooled designs.
Dale just finished installing an IC7100 in his 4Runner. He mounted a TurboTuner II and a Little Tarheel II antenna and used a Breedlove ballmount on the left rear panel, near the fuel filler cover. The head unit is installed via a RAM mount on a stalk along the tunnel next to
the passenger seat in front with the radio body and tuner are mounted on a molle frame in front of the left rear window. The touch screen, and ability to work HF, VHF, UHF, and D-Star all in one unit is what sold Dale on this radio.

SERVICE AWARD
This award is for service and contribution to the SDXA. This year we had two winners:
Pat Murphy N7UVH for his contribution to the club for coordinating our SDXA Nets and Club Log, plus his participation in contests.
Jay Townsend WS7I for his expertise in RTTY operating and sharing that knowledge with our club. Also for his creating and managing the WS7I spotting cluster. This is the oldest Packetcluster in the Pacific Northwest.
One of the great things about the SDXA is that there are always other members willing to help on antenna/tower parties and answer hardware/software questions.
Even on a cold December morning.
Jeff (NZ2S) and Gary (AD7XG) on the tower.
David (WA7F) and Peter (K0NG) for ground crew.
New Yaesu 2800 rotator installed and upgraded 80-10 EFHW 2K.
The new HyGain Hi-tower should be added soon.
Congratulations to Bob Zavrel (W7SX)on the release of his Antenna Theory book 2nd edition which was released two days ago. The first edition went through 4 printings. It is being used as a reference by EE students in advanced Antenna theory courses, practicing radio engineers, and of course radio amateurs.
The primary audience is those new to RTTY and RTTY Contesting or new to N1MM+.
Randy will demonstrate on his screen how he sets up and uses N1MM+ in RTTY Contests.
Bob Lee (N7AU) won the Zone 3 CQ WW 160 meter Contest Plaque with the top score in this zone. This is a wonderful accomplishment from the Pacific Northwest.
We have finished the 2019-2020 Flounders Cup Competition. Randy (K7TQ) has published the final report. Congratulations to both Randy (K7TQ) 1,210,083 points and Gary (K7GS) 1,033,821 points. Enjoy reading Randy’s excellent anaylsis.
Bob (N7AU) petting his rebuild 4 element SteppIR antenna back on one of his towers.
Bob made a bracket, the piece on top of the boom that straps to the boom. The bar on the bracket on top is adjustable to find the center.

The antenna almost ready to attach
Jay (WA0WWW) repainting his SteppIR antenna. Notice the nice raising fixture for his crankup tower.
Bob finished the tower/antenna installation today on his 6 meter antenna. It is an M2 5 element 6 meter Yagi, on which he modified the driven element into a folded dipole and then fed it with 450 ohm ladder line.
This tower/antenna is at one the peaks on his property and the base is anchored in a granite outcropping…all guy anchors are also in granite.
Picture 1: construction and mounting of the base plate…..extra heavy hinge is two telescoped pipes welded to the base and the tower base (standard Rohn backed with 1/4 inch steel plate.
Picture 2: Kubota delivering the top section from the shop 400 feet down
Picture 3: tower lowered
Picture 4 tower raised with the winch on the Kubota.
The tower is 30 feet but it is at the top of the property with steep drop-offs in most directions.
Looks like Murf’s (N7UVH) Hytower is putting out some RF
Field Day for 2020 was different than most years.
Jim (N7ESU), Bob (K7TM) and Murf (N7UVH) aka “Idaho Renegades” did Field Day from a Fire Station in Hayden Lake.
John (K7KM), Janet (WX7P), Mike (K7STO), Chuck (KI7DG) and Mel (N7GCO) used N3FJP Club logging to keep in touch.
