I finally dug out my “QRO” rig, an old Kenwood TS-130S HF transceiver, and got it set up on my deck for some late afternoon operating. On the table with the radio are: to the left is a Shure Brothers Model 440 microphone on a Electro-Voice 423A stand; on top of the TS-130S is a Kenwood remote VFO; to the right (white panel) is an MFJ-948 Versa Tuner II; on top of the MFJ tuner are my RockMite 40-meter QRP transceiver, BLT (Balanced Line Tuner), and dummy load; to the right of the MFJ unit are my Fluke multi-meter (for checking battery voltage), and the West Mountain Radio “RigRunner” 40 amp, 12 outlet DC power strip. Not seen below the table is my salvaged car battery, which currently is my only power supply, and on the railing to the right is a battery charger to keep the battery topped up.

This is the first time in several years that the Kenwood rig has been powered up. So far it seems to be working well.

I finally got an antenna in the air temporarily this afternoon, and got out my RockMite 40, BLT and Nye Master Key.  The 40 meter band seemed very active; at least there was lots of activity around 7.030 MHz, which is the frequency of the crystals currently installed in the RockMite.  Everyone that I heard was a bit fast for me; I was able to copy only about 15% or 20% of what I was hearing.Most of the calls that I was able to copy were in 4-land.  One person was having a ball with his “bug” slowed down to about 15 wpm – I forgot to write down their call, but they had a very distinctive “fist”, with comparatively long dashes.

The photo above shows my portable station:  Battery pack with 8 “AA” cells, RockMite transceiver on 7.030 MHz, Nye-Viking Master Key (model 330-001), NorCal BLT (Balanced Line Tuner) modified to also tune unbalanced feed lines, and my cheap, worn-out Koss UR/29 headphones.  The BLT is feeding a speaker-wire doublet as an “inverted-V” with the apex up only about 25 feet or so.  The tuner handled it easily.

How to operate a straight key April 12, 2008

Video from GHD – “”How To Operate a Straight Key”.  This is an instructional video showing how to properly set up and use (Japanese style) a straight key.  The video concludes with demos of a bug, and a “side-swiper” or “cootie” key.. 

Japanese language, but with English sub-titles.  Nicely done.

BLT Construction September 6, 2007

Well, I finally got around to completing the BLT – Balanced Line Tuner.  It’s not just a balanced line tuner though; it now will tune a coax-fed antenna, and a random-wire antenna, as well as a balanced-line antenna.  It was pretty simple to put together, although I had trouble a couple of times, caused by my shakiness.  Following are some photos of the building process.

Another seven months gone by July 9, 2007

HF9VYes, another seven months of no activity in ham radio. I still have a broken antenna (Butternut HF-9Vx) on the roof (I don’t own a ladder, can’t afford to buy one, and am too weak to climb up from the deck railing), my gear, what’s left of it, is all still jammed into the back of the overcrowded garage, and it is still difficult for me to remember tech stuff, and to figure things out anew after those brain treatments that I had a few years ago. That’s really a bitch, because these things used to be so easy for me. I think that I just need to get motivated to relearn this stuff. Time to break out the books and take some practice tests. At this point, I’m embarrassed to admit that I have an Extra class license. I’m not sure if I could pass a Novice/Technician class exam today, let alone the Extra test.

I’m glad now that I did not succumb to the urge to sell my Kenwood TS-130S rig a while back. Not only is it my only QRO radio now, but it’s my first rig, and more importantly, is also my mother & step father’s first rig. It has a history. It survived life cruising aboard a 45′ sail boat, covering the west coast of the US and central America to the Panama Canal, and in the Caribbean, both in use and in a storage space after being replaced by a Kenwood TS-440S. It even survived the sinking of the boat at the island of Culebra during Hurricane Hugo in September of 1989. Fortunately, the radio was well-wrapped in plastic bags at the time. The 440 wasn’t so lucky.

Let’s see now, I have the TS-130S, but no power supply, battery or otherwise (I’ve almost always operated by battery), no permanent antenna, no space to speak of, although that may change soon if one of my sons really does move out. I do have wire to make antennas with, and can string ‘em up between the house and a tree in the back yard, although anything that I could put up would be fairly low. Vertical might be best, but experimenting is half the fun.

Tiny-Tornado R2a built 001Oh yes, I almost forgot that I do have a couple of QRPp rigs to play with, but my code copy and sending are awful. As with my tech knowledge, I’m not sure if I can copy or send much more than the five wpm that I passed while taking my Novice test. One is a FOX3 that I remember having a few QSO’s with, and a Tiny Tornado or two (say that three times fast!), still unassembled, several unassembled Pixie2 kits, and a few various and sundry accessories, some in the ubiquitous Altoids tins.

I still very much regret selling the Elecraft K1 that I built five or six years ago. I sold it at a time when I thought that the money I could get for it would make a difference with our financial situation at the time. Needless to say, I was not thinking very clearly at the time; a result, again, of the treatments that I’d been having. Oh, well. Building a new one is something to look forward to when I can afford to buy a new kit!

Oh! I just remembered that I have a DK9SQ Vertical Loop antenna. I do need to get a new mast to use it on though, the one I had was damaged by the USPS. The mast that I had was the MFJ-1910, but I think I’d want to get the DK9SQ model to replace it, it seemed stiffer, the pieces locked together better, and seemed stronger overall when I had the chance to examine one at a ham fest a few years ago. Then again, I see that MFJ now carries slightly taller fiberglass models with locking clamps or hose clamps to lock the segments together. That’s a consideration too, though not for the DK9SQ loop.

The photos above show my portable configuration at one time. When I took the pictures I had been operating outside on my deck with the Elecraft K1 and MFJ-564 iambic key (definitely not a portable item). The antenna shown is the DK9SQ; the middle photo is with the antenna all packed up for travel – MFJ mast on the left, the horizontal spreaders to the right, and the antenna balun housing with the wire wrapped around it on the floor. The photo to the right shows the antenna up and ready for work.
