I heard 17M was open but all I heard was ragchewing about amplifiers, not usually a good sign. I QSY'd to 15M and heard KH6ZM Max calling CQ on 21021.00. Max gave me a QRZ at 5W so I cranked up to POWER:10W and he gave me a RST:559. I gave max OMRST:579. Max was using an 3el Yagi and I was using my 400' loop up 15' and my K2. 1820Z.

I heard a little activity on 30m but the antenna doesn't work well there, so I went down to 40m and heard W6JL call CQ. Don was in Fallbrook, CA and running a homebrew "phasing" rig with a DDS VFO running at 0dbM on the RX frequency and with amplification at 450W. Needless to say, he had quite a strong signal, and told me about the DDS and the advantages of direct generation with the DDS. He said he drives his amp with a KX1 sometimes. Don gave me a RST:589 and says his RX design is 100 years old, but I think it is quite a bit updated with the Analog Semi 9854 DDS!

After we said 73 he had 2 other stations calling him on 7037.5.

I activated the PARC XEACT truck at 2200z and made 2 contacts on battery power with the Kenwood TS-440S at 100w to the truck-mounted Cushcraft R5. It loaded up on 17m so I worked N4KZ Dave in OMFrankfort, KY and got a 5x6 on 18.161 SSB. Dave had moved down from 10 and 15m where he heard nothing. Dave was 5x7.

I heard NI7I/MM3 Lee call CQ on 10122.0 from aboard the President Truman sailing from Hong Kong to Seattle. His QTH was 44N 144E. Lee had a 599 with QSB but said my copy was rough and in the QRN. I ran 35W from my HFPacker amp to the 400' loop and my K2.

I applied KX1 Alert 1 to my KX1, which involves putting more turns on the final transistor supply choke. I also did the KX1 Drive change because my power output was down low after the KXB3080 installation.

Radio Shack PowerUp with Anderson Power Poles

I got a Radio Shack PowerUp 12v/12ah car starter on close-out for $19.95. Chris K6DBG ordered a couple of PowerPole chassis mounts (HS-8) from PowerWerx and I fit mine into the case.

  1. First I removed the heavy, unfused battery clamps and set them aside, probably to re-use the wire for something else.
  2. Next, I used double spade lug connectors from West Marine to hook the plus and minus leads from the PowerPoles together and to the plus side of the battery breaker and the minus side of the battery and its charger (which I had to cut and crimp again).
  3. I routed the negative leads through the upper part of the handle area, to keep them away from the charger heat sink, but when I put it together, it still got a bit close.
  4. I covered all exposed + leads (battery, circuit breaker) with electrical tape, to protect them during reassembly. I also put a strip on the back of the charger circuit board as the negative wires ran a little close; something harder would be better.
  5. I cut a small amount of plastic from the thin vanes on the case so that the PowerPole chassis mount would fit. This unfortunately left some holes around the square area where the lighter hack was. I covered these with electrical tape for now.

Here is the connector I made, the inside without the connector, the installation location, and the finished view from the side:

I found an HP-33e calculator in box with manuals and charger being discarded. The batteries had corroded and broken a small tab on the battery door, and when I cleaned the corrosion off the battery tabs on the calculator, one of the broke off. The battery holder itself was in good shape, but it requires NiCd's without tips, so I used some copper flashing (also found discarded) to fashion an end spring. It works great! Here it is before I did the rework, running off an external AA pack.

Top Hat for Pac-12

Following W0RW Paul's directions, I made a top-hat for my PAC-12 short vertical out of landscaping flags ($0.48 for 4) and a UGG-177 (SO-239 backend shield). I used Anderson PowerPole connectors to make it disassemble and stow easily. I haven't tried it on the air yet, of figured out how to attach it securely to the PAC-12. Paul used a set-screw or a thumb screw in his succesful designs.
