Mark is only the 17th person to receive The ARRL Fred Fish Memorial Award.

The Fred Fish Memorial Award was created in honor of Fred Fish, W5FF (SK), who was the first amateur to have worked and confirmed all 488 Maidenhead grid squares in the 48 contiguous United States on 6 Meters. The award is given to any amateur who can duplicate W5FF’s accomplishment. Think about it — confirmed contacts on 6 meters with every grid square in the continental US.

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.

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.

“Introduction to RTTY Contesting Workshop”

Monday, September 21st at 7 PM on Zoom

The primary audience is those new to RTTY and RTTY Contesting or new to N1MM+.

“Using N1MM+ in RTTY Contesting Workshop”

Thursday, September 24st at 7 PM on Zoom

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.

Using the ATV to pull the antenna up

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
