Update August 2016:  keeping the blast from the past below just for fun.  The pix are all at the EW Haunted Castle.  Glad that's gone.

Presently "on the road" so portable ops with short loaded verticals for HF.  Full set of vertical FM and horizontal Yagis for SSB on 50MHz, 144MHz, 222MHz, 432MHz, 900MHz, 1296MHz.  Some LF and VLF listening. Intend to get a hard QTH and set up for all bands.  Looking forward to 630m and 100kHz eLORAN!

Updated the "geneology" section at the bottom with a nice email from OM Cliff K6CEO.  Very thoughtful, great stories, thanks Cliff.  Cliff K6CLS

Blast from the past, pre-2012:

* Present:

Enjoying weak-signal modes on 6m, 2m, and 70cm. On 6m and 2m I run SSB and WSJT Meteor Scatter.

For 6m and 2m I built a "boxkite" yagi - KF2YN design, it's 10' long, 7' wide, 4' high; it seems to meet its design 10dBi on 6m, 15dBi on 2m. This image shows it temporarily mounted at 12' high, it really needs to go up about 25 or 30 feet.

image shows me standing in front of the boxkite yagi

Using a converted SB221 for amp on 6m (thanks WD6DBM). Using a Mirage 170W (thanks W6OMF) brick amp on 2m.


70cm EME station is 4x M2 12el on an M2 H-frame, an ARR preamp, WGF F70 4CX250 amp (thanks K6JEY), for portable Mirage 100W (thanks W6OMF) brick amp, and my FT-847 (thanks W8WN).

The 70cm EME station is portable, because I have trees to the east, trees to the west, and "birdies" all over the band. This is the power supply: Group 31 (105 AH) AGM 12v battery, solar charger and 15W panel, N8XJK TGE voltage booster.

* How I got started in ham radio:

We needed to track high powered rockets - they fly out of sight, and land kilometers away, which makes it difficult to get the expensive parts back.

I was always interested in ham radio, never could learn code. Finally I got Technician license in February 2006. Since then I have had lots of fun doing 2m & 440 phone, 440 IRLP, APRS, packet, but mostly just 70cm tracking of high powered rockets - check out www.nar.org.

The photo (by George Wagner) shows my Performance Rocketry carbon-fiber Mongoose 98 (98mm diameter, 2.6m length), launching September 18, 2009 at AeroPAC's XPRS launch, on a CTI N1100 motor (15000 newton-seconds). The rocket flew to apogee at 10445m, maximum speed was Mach 1.7, maximum acceleration was 11Gs. The rocket quickly flew out of sight, but we could still hear the motor burning. It took about a 45 seconds to reach apogee, and about 15 minutes to tumble down to 250m, where the main parachute was deployed for a soft landing. It landed about 6km away.

The rocket carried a Big Red Bee 432MHz tracker. With my M2 440-6SS Yagi and Yaesu FT-60, we never lost signal and knew the bearing, so we drove right to it. What a great feeling!!


* How I got started in HF:

Greatly encouraged by NE6RD's persistent nagging, studied and passed Element 3 (General) test 2009/10/03. Bought an old Cushcraft R7 at the swap meet (thanks AK1P), put it up on the roof on 10' of IMT conduit (thick-wall). A friend sold me his old ICOM 735 (thanks KT0ZZZ), woot now I am on the air! First HF contact was KH6TE, wow that station puts out a great signal.

More interested in digital modes, so I built a soundcard <-> radio interface, with serial port RTS -> XMIT control. Tried Digipan, fldigi, HamScope, MixW, but ultimately I prefer Ham Radio Deluxe with DM780.

Just for fun, studied and passed Element 4 test on 2010/03/06. Since then, doing lots of PSK, HF SSB, antenna and scratch building. Enjoying JT65-HF.


* HF Station

Here's an out-of-date diagram of the HF portion of my home station. It's out of date because I burned up the tuner so instead use a 4-way switch between the HyGain meter and the antennas. So now the AL811H (thanks WD6DBM) can run full 800W on all bands to either antenna. Also, the old Compaq laptop died so I built a new station computer, based on AMD Fusion, ASUS E350 PRO mobo, 4GB RAM, 60GB SSD, Win7. Tried Ubuntu 10 & 11a, don't like it.

The R7 does not give full bandwidth on 20m and 40m. I adjusted its minimum SWR for the CW portions (7000-7100, 14000-14100) because right now I'm mostly interested in digital modes and that's where the action is in those bands. I can use the tuner to get good SWR in the phone regions of those bands (7175-7300, 14225-14350), but emissions are really poor. Although it is not rated for the band, R7 resonates nicely on 80m/75m, and I've made some great QSOs there. I am afraid to use the amp at 80m.

My homebrewed 20m+40m fan dipole shows better than 2:1 SWR across 40m, so makes up for what the R7 doesn't do in phone part of those bands. But the dipole hangs really low, about 18 feet on the ends and sags even lower in the middle, so it's really a cloud-warmer.

Here's a photo of a hexbeam I put together for 10m. It was really inexpensive and easy to make and it works exactly as described. It is a nice complement to the R7 for 10m operations.

All the parts of this station were inexpensive, and I have had a lot of fun putting it together. And it does everything I want, for now... although, I have a really long list of projects. The list gets longer the more I play with ham radio!


* K6CLS call sign geneology:

My original (Technician) call sign was KI6BXH. As a kid I always wanted my initials "K6CLS"; I was disappointed to learn that it was already assigned... After licensing Technician in 2006, I discovered the call was unassigned, so I got the vanity call sign. Recently I wondered, who originally had the call? I looked at the QRZ 1993 call book, the oldest online, no information, which meant it hadn't been assigned for 10 years at that time. I asked W5YI to look in their call books: $14 later, I got the answer: Anthony J Scarfile, in San Jose, CA, from the 1962 call book - before I was born! Unsurprisingly I had no luck finding Mr Scarfile in the phone book, SSDI shows one person b1927 d1990.

update from Cliff – K6CEO, Los Angeles:

I happened to come upon your call and bio entry on www.QRZ.com and noted your interest in finding out who held your call, K6CLS originally.   I have one, old Call  Book, the Spring 1959 version, which has an interesting entry for your call’s (K6CLS) original owner.

As you already know from your detective activities, Anthony (K6CLS -Tony to me!) was the holder of that call.   But in the 1950s, Tony was an active 2-meter ham and I talked to him on several occasions from my apartment in Hollywood  on 2-meter AM phone.

... In any event, please see the attached “.jpg” scan of part of page from the Spring 1959 Call Book.   Note that K6CLS lived in Hawthorn, CA (my adult daughter appears to live just 2 blocks away from that address today).   If you wish to find more data on the call, you might write a short note to that address and see if any of his family still own the home.


Up to a few years ago I had 2, older Call Books but they were printed on highly acid paper and just fell apart when I tried to consult them.  Into the garbage they went, sadly.    The FCC kept historical records on 9 track magnetic tape, I have been told by friends that work for the FCC.   However, these tapes are big, delicate and the FCC long ago just deep-sixed all them many years ago.   Gone forever is the historical record for all call – EXCEPT there may be some Call Books still readable – somewhere in the world.

Note that in those days, say from 1946 to the 1970s or later, calls (unless you has some “pull”) were assigned alphabetically.   So, all my friends at Hollywood High School (from 1950 to ’54) got issued calls like this:   W6KPM, W6NJU, W6UKB (those from 1950 to ’52), and the “W” call ran out, so they started on the “K” calls.   My friends and my call K6CEO, K6CBZ (Jack, tried to game the system and get K6CBS and almost made it!), K6CKK,          K6CXF from 1952 then new freshman at the school arrived and drew K6ELN, K6ELL, K6ELX IN 1953.   Some of my friends from those years are still active but most have newer calls.  Your call probably issued about 6 weeks after mine, originally and I got my call in July 1952.

...  73

Cliff – K6CEO,  Sr. Engineer/Scientist – The Boeing Co., (retired)

Thanks, Cliff!!

Cliff pointed out that call sign research is difficult because the old call books were not printed on archive paper, and are now in poor condition.  So if you have an old call book, you have some small treasure.   I'd say, put it to use... carefully!!
