More "Canned Seafood" Homebrew CW, from KA4IBG

Bill:

My xYL hates sardines, but they look good together !

In the late 70's the community had a fetish for canned seafood and DC receivers. Do you remember the 80m Sardine Sender ? How about YL Special ? (QST Oct and Jan 1979.) I married them together in a kludged-together box made out of a bent rack-mount panel and defunct aluminum chassis cover.

The bottom board is the rock-bound transmitter. The upper deck is the receiver board. The little mini box contains VFO (so cute.) The 741 audio board is tucked under the scrounged ¼ inch jacks.

Super simple, but lots of fun. It's a handy rig for the week at the beach, although 80m propagation and beach week are 6 months out of phase.

Solstice Special: Midwinter BBC Messages to Antarctica

Thanks to SWL Post for alerting us to this wonderful annual event.  BBC SW stations send a special program to the UK crews at the Antarctic bases.   SWL Posts asks for listeners to record this year's program:

Here is an excellent recording of the 2015 show.

A Fishy Rig: Herring Aid Five, Tuna Tin Two, VU2XVR Key

Haunted by a fear of rapid expulsion from the QRP Hall of Fame, I decided that I should immediately do something to establish some form of QRP street cred.  Looking around the shack, I realized that all of the ingredients were there:  My Herring Aid Five Direct Conversion receiver (completed after only 38 years), my Tuna Tin Two transmitter, the VU2XVR key that Farhan gave me, one 7050 kc  FT243 crystal.   I put it all on a piece of scrap plywood. A couple of nice connectors from W8NSA supported the DPDT T/R switch and the coax connector. I keep the receiver LO running all the time.

Now, let's be clear: running 250 milliwatts, rock bound with a Direct Conversion receiver that tunes both sides of zero beat is not for the faint of heart.  The log book does not fill up rapidly. But hey, I made one contact the following morning.  K1PUG said I was 559 in Connecticut.

KI6SN's 89-Cent Project Box Chassis

Eric 4Z1UG had a great "QSO Today" interview with Richard Fisher KI6SN.  Richard mentioned his method for making project boxes.  The commercial versions are getting very expensive, and the used ones are now hard-to-find at hamfests.  So use Richard's technique to roll your own!

Dino's HW-8 Mods

Bill -

Enjoyed the recent Hamvention interview with Ed Hare and your comment about him and a Heathkit HW-8 QRP rig.  I recently rescued the HW-8 I bought on eBay that had been sitting in my project queue for several years.  As I was refurbishing the rig I found that John KC9ON (http://kc9on.com) has several HW-8 mods that are very reasonably priced and I incorporated in the the refresh.  They included replacements for the audio amplifier and the T/R relay, the “miniYAK” electronic keyer that I installed internally and built-up a external control dongle for the keyer.  Cleaned up the additional audio filter that the previous owner had installed (ancient MFJ CWF-2 op-amp filter, surprisingly still available from the MFJ Vectronics brand, model VEC-820K) and did a complete realignment of course.  The T/R replacement includes provision for a red and green LED that indicates that the rig is in the receive mode (green) and transmit (red); I was able to mount them directly behind the relative output meter using a piece of plastic drapery hardware (always pays to keep that kind of stuff!).  Finally installed a fresh S-meter mod.

RF output is ok on all the bands except for 15m and I still need to figure that out.  Getting rid of the old Molex power connector and replacing it with a Powerpole was a real plus I thought.  Have swapped out the PA transistor with several different types but the one the last owner substituted in seems to be the best (ECG488).  Have to admit I’ve never been a devoted QRP guy but love the community for it’s technical bent but since I’ve been looking for some new challenges I thought this would be a enjoyable one.

As you’ve pointed out Mike Bryce’s HW-8 handbook is a must have for anyone updating their radio and there is also a seminal 2-part article series in CQ magazine that probably started the mods craze; they appeared in the August and October 1977 issues of CQ.

Here are some pix of the clean up process and shows I’m not afraid to drill holes in a boat anchor to make it more useable!

73 - Dino

Here’s the new audio board installed:

The additional audio filter with the new 5-pole selectivity switch put in by the previous owner…had to add some audio coupling caps and clean up all the wiring.  The plastic piece over the meter was from some old drapery hardware and it now holds the RCV/XMT green/red LEDs:

I replaced the original S-meter mod with a proper terminal strip (old parts were just hanging in the air).

Here’s the solid state T/R circuit that replaced the mechanical relay:

Les Moxon, G6XN

I was on 40 SB tonight talking to Don KC5YR. He is the creator of the web site known as the Moxon Antenna Project: http://www.moxonantennaproject.com/   That site had this great picture of OM Les Moxon, inventor of the wonderful antenna that bears his name.  I also found this old QSL card that shows some of Les's homebrew gear.  Les has been a Silent Key for many years now, but his legacy lives on.

FDIM: Bob Crane Interviews Ed Hare W1RFI

I always associate "Ed Hare" with that picture of him holding an HW-8 in the ARRL lab.

I was supposed to edit this one a bit at the beginning, but I forgot.  Sorry about that Ed. 

Thanks to Ed and to Bob Crane for the interview.

Stay Thirsty My Friends --- A Very Inspirational Article

There is no real connection to radio here, other than the fact that some of us are in this guy's age group, and that we have had a few Dos Equis Guy memes on the blog.  But do yourself a favor and spend a few minutes with this article.  You will be glad you did.

Put Yourself on the BITX Map

Seeing the topics for regional operator lists got me thinking.  If words are good, pictures are better.  I set up a google map that you can add yourself too to help visualize where everyone is located.  I was going to add people that responded to the other topics but out of respect for privacy (and my laziness) this should be entirely opt in only.  The map is only accessible with the link below.  The interface is reasonably intuitive but I will do my best to explain how to add yourself.
