Introduction (or, why buy a 40-year old radio?)

I bought a Kenwood TS-520 last week.  It's about 40 years old or so.  It seems to be in pretty good shape.

So, what is it?  And, why did I buy a 40-year old radio?

A little background.  I first got my Amateur Radio license in the spring of 1986, my senior year of high school.  My friend Fred and I took the Novice classes together; we learned radio theory and Morse Code (5 words per minute).  He was licensed as KA9VAW; I got KA9VDC as my call sign.  That fall, I also passed the Technician test.

I didn't do anything at all with my license.

I hung around the W9NAA club station at college a couple years later, and I listened and I watched.  My Morse Code skills, left untended, had evaporated by this time.  I looked up "C" and "Q" on the Morse Code chart on the wall, and was struck by the sing-song nature of the CQ call.  I said "I just love the way that CQ sounds."  Dr. Moench (the club sponsor) happened to be tuning through the bands at the time and came across a CQ, and said "You mean like that?"  I has too much pride to admit that "CQ" was all I knew of Morse Code at the time.

A couple years later, after I was married, I took a trip with Fred and Dave (KB9FBL) to the Dayton Hamfest.  I picked up a Yaesu dual-band HT, a mag-mount antenna, and a 12V power supply to bring home.  I think I paid $140 for all of it.

I used an SWR meter to tune the mag-mount to a local repeater; I often operated from the apartment using a filing cabinet as a ground plane.  When our college hosted one stop on the annual Sunrayce solar car challenge, I joined a group of other hams in technical support around the campus, working with net control to keep everything going.  I remember meeting Keith, WA9DRO, who was acting as net control, and shaking his hand.  He had two or three radios going and somehow kept on top of all of it.  As I walked away from the net control table, a fellow ham said to me, "You do realize that Keith is blind, right?"  I had no idea.

I made up QSL cards with my own phonetic call sign (Kilo Amperes, Nine Volts Direct Current).  I don't think I ever sent one.  I used to spend quite a bit of time chatting with Ken, KB9BRJ, on the drive into work - as he and I lived about a half-mile apart and would often see each other on our respective commutes to and from Terre Haute.  A couple years later, I lost interest.  In 2001, my license expired due to non-renewal.

Fast forward about ten years, probably to sometime in early 2011.  Keith and his family started attending the church where my family are members.  He and I are both musicians, and we started chatting.  The conversation turned to ham radio, and I mentioned meeting him back at Sunrayce probably 15 years earlier.  I told him that I had let my license expire; he said "well, you should do something about that."

So I did.  Since my Technician license was issued before the spring of 1987, it's a "Grandfather Tech" license.  In order to get reinstated, I only needed to take the Tech test again and I would be issued a General license.  So, in November 2011, that's what I did.  I was issued a new call sign (KC9UYW).  I had given away the HT and power supply some years earlier, so here I was again with a license and with no radio.  Keith let me borrow an HT (an Icom, I think).  Keith is one of the net operators for the local SkyWarn net; he got me interested in SkyWarn, so I went to a couple of the spotter classes and participated in a few weather nets.  I even took the borrowed HT into work during one particularly nasty storm and offered a hail report while watching out the window.  One of the first people I talked to after getting my license was Keith; the next was Ken (now W0THI).

A year or so later, I picked up a Yaesu FT-7800R dual-band mobile radio from eBay, along with a Comet dual-band magmount antenna.  I also picked up an Astron 35M power supply so I could use the radio from home.  I made a couple twin-lead J-Pole antennas and was hitting a repeater 20 miles away on 5 watts from inside my house.  That was pretty cool.  The J-Pole seemed to give out after time; I think the cat or the dog chewed on it.  So, after some research and study, I built a 2M 3-element yagi out of copper ground wire and scrap wood.  Now that gets into the repeater with room to spare.  I even had a nice QSO with Ken (25 miles away) on 2M simplex - on low power.

I started attending the Clay County ARES meetings to figure out how to help out if needed.  I met a couple great people there and I hope to keep involved.

But something was still missing.  FM repeaters are great, but I could tell that what I wanted to do was have a conversation with someone far away with nothing between us but alternating electrical and magnetic currents flung through the atmosphere.

So, I started looking at HF radios.  Some of the newer ones are really spiffy, but they're also kind of expensive.  Some of the older ones (from the 80s and 90s) are pretty solid with a wide range of features including built-in antenna tuners, support for computer interfaces, etc.  But, even those used radios seem to cost more than I wanted to spend to start out.

Earlier this year, three things happened at about the same time:  I started studying for the Extra Class test, I started learning Morse Code again, and I discovered Kenwood hybrid radios from the 70s: no antenna tuner, no computer interface - in fact, they have tube transmitter finals that need to be tuned before transmitting.  (I know, right?  But this is the way all radios were before solid state transmitters came along.)  And I realized something:  I had never taken the General test, where a lot of radio and propagation theory lives.

So, I made a decision:  I wanted to get into HF radio, but I wanted to get into it on the ground floor.  I want to understand why and how my radio works.  I want to manually get a feel for the HF bands using a radio that will help me with this.  I want to build my own antenna(s).

That's why I bought a TS-520.  I got a pretty decent deal on it, I think.  It didn't come with a microphone.  (By the way, an eBay lesson:  If you buy something on eBay, don't keep watching it for similar items - I saw another TS-520 sell 3 days later for the same price - with an antenna tuner and a microphone.  Sigh.)

The Interwebs have lots of great information on Kenwood hybrids - the great K4EAA Kenwood Hybrids site, a Yahoo Groups site, and lots more.  They're well-understood, and they can be worked on by mortals like myself.

I still talk on the 2M repeaters - usually to Ken and Keith.  You'll probably hear more about them in upcoming posts.

I intend to use this blog to chronicle my journey in HF radio.  The next couple posts will follow my ongoing testing of the rig (I have 14 days to return it if it doesn't work).  Let's see how this blogging thing sticks!
