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
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
and my K2
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
After we said 73 he had 2 other stations calling him on
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.
Chai in Bangkok was booming in S9+20 on 14.070 but then faded out.
First Buddipole QSO K7MQV
First buddipole qso, KX1 From PARC
who gave me a 339 though my signal seemed to come up a bit. 7039.59. Jim was using 70w into a screwdriver antenna from QTH nr Ellensburg, wa
on 21.032.37 persevered and heard my 5W to the 400' loop from the
K2 in the FQP.
I gave 599 CA and he gave me SAR.
I heard WK2G
/4 calling CQ FQP on 21.038 and answered at 5W from my K2
to the 400' loop.
I gave 599 CA. He gave county as PAS.
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
to my KX1, which involves putting more turns on the final
transistor supply choke. I also did the KX1
change because my power output was down low after the KXB3080
I worked HR2/LU1DY
Gustavo in San Pedro, Honduras on PSK31 35W at
225Z with me 35W K5OOR HFPacker Amp and K2 to the 400' loop. Gustavo
gave me 579 but I had QSB and gave him 459 QSB.
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.
- First I removed the heavy, unfused battery clamps and set them aside, probably to re-use the wire for something else.
- 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).
- 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.
- 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.
- 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:
- The plus lead from the charger to the
battery pulled off the charger board, giving me a few anxious moments
until I noticed that there was a solder pad with wire impressions still
in it, so I found out where it went.
- I unnecessarily cut the yellow
wire on the transformer, because I didn't know that it popped right out.
- If I had it to do again, I would make the negative leads on the
connector shorter to keep them further away from the charger voltage
regulator heat sink.
- Make a plastic frame to cover the remaining holes around the powerpoles.
- Check to make sure that the negative wires aren't getting too warm and close to the charger voltage regulator heat sink.
- Saw the plastic posts off the back.
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.
I heard K7TQ
Randy in the QRP ARCI contest on 14.061.62. Randy gave me 559 ID NR 8336. I responded 559 CA NR 12046 at 5W into my 400' loop from the K2. 2032Z.
My QRP ARCI number is 12046
I was trying to get DL5MEV
in Bavaria, but he was runnign 600W and didn't hear me. I went down to 18.157 Max IW0GXY
gave me a 5x3 from Rome on 18.157 with my 35W to the loop.
The loop has come down a bit at the feedpoint...
