Prescott Valley, AZ

I was first licensed as a teenager while living in Newport Beach, CA at the Los Angeles FCC Office on July 2, 1951, receiving the call: WN6NIC. This was the first day that novice tests were given in the U.S. 
Within a couple of months, I upgraded to General Class and dropped the “N”. Sometime later, I upgraded to Advanced Class.
I operated mainly on HF CW for several years. I also worked 10 meters AM mobile when, in those days, 10 meters was wide open. I was able to work DX – typically Australia – from the mobile running 25 Watts just about any time during the day. 
Ham radio took a backseat while I was raising a family and I forgot to renew my licenses. So in 1975 while living in a small community in the high Sierras of Northern California, I travelled twice to the San Francisco FCC office and retook all of my ham license tests up through Advanced Class on one trip and I took the Extra Class and First Class Commercial Radiotelephone on a second trip a month later. I was then issued my current call: N6MY. 
I still operate mainly CW on the HF bands, typically on 20 or 30 meters.   July 2017  
Ray is the owner of the 3600 IRLP Node and equipment which he connects to the MMRG 442.150 Repeater on Mingus Mountain.      February 2018	
Text Box: K7POF      Bob Sitterley      Chino Valley, AZ
I became interested in Radio at the age of nine in 1947, but I wasn't licensed until many years later.  I was first licensed in Phoenix, Arizona as KN7POF in April 1961.  I became K7POF in April of 1962, and kept that call until 1965.  Upon moving to Southern California I was issued W6BTV which I held until 1977. The W6BTV call is now The Chino Valley Vintage Radio Club call. 

I moved to Prescott, AZ in 1977 and got the K7POF call re-issued to me. About that time I joined MMRG. After two years I moved back to Southern Cal but retained the K7POF.   I moved to Chino Valley, AZ in August of 2001. 

Most of my Ham life I operated HF SSB and AM.  However in recent years a good share of my time I have spent on VHF FM and UHF FM.  During the 1980’s through about 2006 I collected and operated ham equipment from the fifties and sixties.  Now as I am getting older I have been trying to sell  off things that I no longer use. 

I am the president of the Mingus Mountain Repeater Group and a member of the tech committee which keeps the Mingus Mountain repeaters working and in good condition.  I publish the newsletter for the MMRG every quarter and circulate it among members.  A yearly meeting of members is held at my location in Chino Valley every May.                                                                             (July 2017)

Phoenix, AZ

My first amateur radio license was WN8CDR, issued to me in Trenton, Michigan.  When I received it I modified an ARC-5 transmitter for 40 meters and worked 40 meters CW trying to get a WAS.  I was using a BC-342 receiver to start with, and the use of a borrowed Collins 51J3 receiver several months later made me realize what I had been missing.  However, those months with limited equipment were great training for a beginner using CW.  The move to Phoenix came before I was able to earn the WAS, so naturally it meant abandoning those states I had earned.  Did I get the WAS here?  No.  I still don’t have it.  By that time I had a general license and finally upgraded to an amateur extra.  My Arizona call became WA7EDI, and with a new Drake TR-3 I talked to the world on SSB.  In 1968 W7CAFand I, at the ARRL Southwestern Division Convention, set a world record at 40,100 MHZ from the Townhouse Hotel to the First Federal Savings Building 3,720 feet away.   You may know W7CAF by his present call K7GH, Gary Hamman.

Presently I work 10 meters and have 58 confirmed DX entities toward the DXCC.  I am a member of the Arizona Amateur Radio Club as well as the Mingus Mountain Repeater Group. I enjoy writing articles for both clubs in the ADAW and appreciate any input from members.  I am a VE, and I’m especially happy seeing young people become interested in amateur radio.  I enjoy attending hamfests and conventions.  There is always a lot to learn by doing so, and it’s especially nice to see friends in person that we talk to on the air.  I’m glad ham radio entered my life back there in Michigan!

Hartley Gardner
Phoenix, AZ
Hartley is one of the premier RF techs in the area, He was involved in the technical aspects of the Mingus repeaters for many years and without his expertise the group would be in serious trouble.

Hartley, in recent years, has been tied up with the Civil Air Patrol so his time for MMRG is limited.

Sonja is also one of the 1975 Charter members of MMRG. She is also a big supporter by putting up with all the time that Phil WA7UID has devoted to MMRG. She is not technical as far as radio is concerned but has been very active at the social gatherings. This can be seen in pictures from all the various picnics and work gatherings at the Mingus Mountain site.
