Please call me Robin. I am the retired Chief Engineer for a full power FM broadcast station KCUR-FM in Kansas City, MO.  I retired in July, 2014.  I also am retired as Chief Engineer from WNIU/WNIJ in DeKalb, IL.   I am on the Board of Directors of the Association of Saints Church Radio Amateurs (ASCRA is a non-profit organization).  I am also the immediate past President of ASCRA. 

I usually operate and sometimes call the ASCRA 20M net on Sundays (US) on 14.287MHz +/- at 21:30Z Standard Time or 20:30Z Daylight time (local time remains the same).  We (ASCRA) also have a 40M net on 7.190MHz one hour before the 20M Net for ASCRA Members in the Kansas City area.  If you check in, I look forward to meeting you.

My favorite band is 40M.  I have a 20M vertical loop mounted between two trees at 13 Meters.  I also have a GAP Challenger.  I have a full power Palstar tuner driven by an Ameritron AL-1200 amp.  My rig is an Icom 746pro.  I also have an IC-7300 that I am getting to know.  I use a Heil PRO7 headset.  A footswitch completes the Station.

I was first licensed as WN4NZP in Memphis, TN which became WB4NZP when I upgraded to Technician from Novice.  When I moved to North Dakota I received WD0FEN which I held simultaneously with WB4NZP when this was legal.  One was licensed in Memphis, TN and the other in Bismark, ND.  I worked long and hard to get my code speed up for the 20 WPM Extra license so that when they started the Vanity Call system in 1996, I would be eligible for W0FEN.  I applied opening day and received the desired callsign.  When I renewed the w0fen vanity call for the first time,  the FCC messed up and changed my call to a non-vanity call.  It has been that way ever since.

The Family has a Club callsign of KR0SS.  I am trustee for the Cross Family Amateur Radio Club.

Besides Ham Radio and the vocation of Broadcast I enjoy camping. I walk several times a week to stay fit.

Please use eQSL or LoTW.  Please no QRZ.  If you send a card I will reciprocate.

I live just off the original wagon train trails.

Technical tales:

I was at the transmitter at WMPS, Memphis, the morning that Rick Dees was on the air [1974].  The Station was also in the process of modifying the directional array to add another tower to be used as the daytime AM antenna and move the FM from 380 feet to 575 feet.  It was a slow process. I came in and signed on the transmitter at 4:50 AM on the 5 KW directional pattern.  That day the Corporate Engineer told me that he had switched the daytime radiator over to the 600 ft tower--BUT he did not have time to reload the transmitter at the 10 KW power. He said he had no idea how it would load and what the PA readings would be.  I would need to flip a contactor with a 2X4.  So at the appropriate time, I turned off the plate on the 1947 RCA 10 KW transmitter. I started the process of running around back of the transmitter flipping the relay with the board.  I ran back around the front and flipped the plate switch back on.  Nothing happened. I ran back around and had forgotten to close the phaser doors.  The transmitter came up.  All was good, but wait.  This was a 10 KW transmitter.  The normal readings were 9200 Volts on the Plate with about 1.45 Amperes of current.  The readings that morning were about 8800 Volts and about 2.25 Amperes.  In other words the transmitter was VERY HEAVILY loaded.  It was putting out more power than it was designed to.  Let’s do the math.  9200 X 1.45 X 0.80 = PA Volts X PA Current X Efficiency = 10.5 KW.  This was the normal operating power.  OK now let’s do the new values. 8800 X 2.25 X 0.80 = 15.8 KW. The transmitter unbelievably stayed on the air.  It moaned and it groaned all day.  The Engineer on Duty that relieved me was astonished that it was working. To put this in better terms, the 10 KW transmitter was putting out more than 15 KW. The Station was on the air using a tower that was closer to a 1/2 wave vertical antenna rather than the just over 1/4 wave antenna. Talk about coverage with 50% more power than normal.  Now there is more to this story than just that.  Remember that I said that Rick Dees was on the air?  Well he complained all during his air shift ON THE AIR about the Engineers at the station.  I could have done many things.  These could have been to cut him off every time he said something.  But I didn’t.  I called the Corporate Engineer that afternoon and told him what went on.  I never heard him say anything about Engineers again.


When I was living in Great Bend Kansas a friend of mine asked if I could put an AM radio station on 160 M for a contest.  Of course I could.  Soon we were at KFRM, Salina, Kansas.  KFRM was a 5 KW station on 550 KHz.  It was a daytime directional using 3 towers as the antennas.  Each tower was 500 feet tall.  Not that many transceivers or amplifiers had 160 Meters on them at that time [1983].  This friend was WB0TOM.  We used his call and transceiver for three contests that year.  The ARRL Phone and CW and the CQ 160.  It was a two day contest.  Of course we could only operate while the AM station was off the air which was sunset to sunrise.  So on Friday night just after sunset in December on on the plains of Kansas.  We had a couple of Handhelds and got the tuner set up so that the antenna was flat across the 160 Meter band.  Then we ran all night.  I remember someone asking ‘how many Kilowatts are you running?’  So that next morning, I was out at the center tower and it is COLD.  The lock seems to have frozen.  Time is ticking by.  Struggle with lock. Tick-tock.  Get in lock open. Tock-tock.  Pull clip leads off my Heathkit tuner.  Tick-tock.  Get the jumpers plugs back in sockets.  Tick-tock.  The station goes back on the air with 5KW where I just was.  Then repeat the same sequence the next morning.  We worked WAS-48 in one night.  We heard KL7 and were told that KH6 was calling us.  The advantage of a fantastic vertical radiator is just that it is vertical.  We heard lightning out many hundreds if not thousands of miles.  It must have been the noisiest antenna I have ever used.  The quiet winter months were anything but quiet on receive.

Robin, w0fen
