MEETING DATE, TIME & LOCATION:AE7AX 40M CW TRANSCEIVER
Saturday, November 18th, 2017 10:30 a.m.
Koelbel Library

You don’t have to be a member. Everyone is welcome!

James Kretzschmar AE7AX will be traveling all the way from Cheyenne, Wyoming, to discuss homebrew construction. The presentation will feature his recently built homebrew 40-meter CW transceiver. The 10-watt transmitter section uses six switched crystals for frequency control. The seven-transistor direct conversion receiver utilizes three of the semi-conductors for the mixer/detector, two for the oscillator, and two for the audio amplifier. The presentation will include discussion of schematics for the rig, construction techniques, and the joy of homebrewing.

Our meetings usually end with an optional luncheon at a nearby southeast Metro area restaurant for a lot of fun chat and chow!

 

The AZ Connection

[NOTE: This article is under repair. Via the oddities of the InterWEB an entire chuck in the middle has completely vanished! It will soon be fixed and play can resume — ed. 07/16/17]

During a recent trip to visit my oldest son, Kevin, and his family in Scottsdale, AZ, (and assist in a few home improvement projects!), I packed up a respectable field station and buried it in my single checked travel bag. I figured I had better start working my portable ham radio chops again, since I knew I would be drifting down to Arizona when the chill winds roar up here in Aworked stations on both coasts and a few back into Colorado and locales in the Midwest. It was great fun.

The station is rounded out with a Case Logic station bag, Palm paddle, earbuds, a compact logbook and, of course, an analog pencil.

In the evenings, after the hot sun vanished, Kevin, his family, and I used my Yeasu FT-60R to chat with son Trygve KB0WNZ back in Denver via IRLP.

With the panoply of flat trail/travel ready rigs available, a Buddipole and a little gumption is all you need these days to take the great hobby on Earth with you wherever you go.

EPILOGUE

The painter’s pole and nylon cord were left behind in Kevin’s storage shed for future visits. The Buddipole has since been sold. I do that. A lot. However, I like to make antennas, and I am building a pair of Buddipoles using the original homebrew designs by Buddipole inventor Budd Drummond W3FF. No scorpions were harmed in the making of this article.

CQC Top Ten April 2017

The Top Ten … reasons why oldtimer QRPers really miss active sunspot cycles…

10. Working your East Coast buddy on 80 meters using a gold filling in an upper molar.
9. Beating out kilowatters in pile-ups.
8. Working Eastern Europe BEFORE you walk into the shack.
7. Finally – getting some Q’s with that “magic” antenna that never really worked quite right.
6. Worked All States BEFORE the neighbor kid tells you he cut your feedline when he last mowed the lawn.
5. The dog jumps ten feet every time you key the rig.
4. DXCC on 160 meters.
3. You can just lay out your dipoles on the ground.
2. Two words: CLEAN SWEEP

And the Number One reason why oldtimer QRPers really miss active sunspot cycles…

Constantly uttering the phrase on phone, “Honest, I’m only running five watts.”
