Boatanchor Dreams

Greetings Bill and Fellow Solder Melters,
Back in 1965, I bought a brand new HT-37 from a radio store in Pittsburgh, Pa.
It had been tucked away by the owner for his own personal collection.
He finally softened and sold it to me. The Hallicrafters HT-37 became by Big Dog for many years.
In 2005, I fell on some difficult times and sold it. I regretted the departure moments after the exchange.
Well, finally after lots of searching, the right unit came along.
Here are a few pictures of my excellent E-bay buy.
I will begin to dig into the electrical status of the rig later this week but the unit seems well cared for and not abused.
I will keep you posted. It will be happily married to my Drake 2B and Q-Multiplier after it passes muster.Yes fellow hams there are still gems out there for your collections. Just wait for the right buy and then go for it!

Bill,
I know you would appreciate this. Got an email this morning from a local ham who was getting rid of some “junk” radios, wondered if I or someone else could use them. Once I heard I got over there to pick them up. Among the usual, real junk was a Hammarlund HQ-110C receiver, in the original box and a Johnson Viking Ranger, also in the box. With all the manuals as well. The boxes are showing their age, the Ranger’s being not much to look at. I am told neither works and haven’t been looked at / turned for at least 20 years. What a find! They are very clean and complete, as far as I can tell.
The plan is to restore them to pristine condition and, hopefully, use them in one of the local museum as a working station.

My New Shack Heating System: Heath, Halli, Hammarlund and Drake

Temperatures dropped over the weekend and I had to fire up my new heating system for the SolderSmoke shack. See above. Heating by Heath, Halli, Hammarlund and Drake (sounds like a law firm doesn’t it?). I’m happy to report that those old filaments take the chill off quite nicely while adding a nice aroma to the room, along with some very pleasing lighting effects (I especially like the green glow from the DX-100 tuning dial).

The Azores-17 DSB JBOT project is (I think) complete. And I did include a low pass filter. In keeping with the finest of ham radio traditions, now that it is cold I will go out and work on an antenna.

Getting Ready to Listen for Sputniks

October 4 is approaching and I DO NOT have a homebrew Sputnik transmitter in the works. I hang my head in shame. AA1TJ sent me the parts, but they went to one of my many APO or FPO addresses, so I suspect they are orbiting around the Azores, or London, or Lisbon, or Rome. I’m sure they will reach me eventually.

But I have come up with a way to participate in this historic event even without a homebrew replica transmitter: I will be listening for the Sputnik transmitters, and I will be doing so with a receiver of that era, a receiver that could have been used by some earnest teenager eagerly tuning for the beeps of the overhead RED MENACE. Like the intrepid young man in the picture. What a great shot! Wow, that’s Roy Welch W0SL, then W5SLL! When I got into satellites in the Dominican Republic in 1994, the first tracking program that we used was Orbits II… by Roy Welch. We loved that software. From the AMSAT page: “Roy and his two-year-old daughter would put the radio speaker in a window and then go outside and listen to the strong signals while they watched the third stage booster tumbling end over end like a bright pulsating star as it passed over in the evening sky.“

I will be using a Hammarlund. Moore’s “Communication Receivers” says my HQ-100 was made between 1956 and 1960. PERFECT! (Mine was probably in the Dominican Republic on October 4, 1957.)

By the way, I got into the old Electric Radio magazines again, reading some more of Lew McCoy’s wonderful reminiscences. He reports that during the Sputnik period he — and apparently others — were asked by their Uncle Sam to use their skills to monitor Soviet space activities.

Let the beeping begin! (Sputnik signals recorded by Roy Welch:

Shack Rehab

Every once in a while we all need to attack the clutter that grips our radio shacks. That’s what I was doing this weekend. I got rid of a lot of junk. And I reorganized the operating position. On the left is the HQ-100. I plan on putting the K2ZA DX-100 underneath the HQ-100. To the right is the famous Drake 2-B/Hallicrafters HT-37 combo. Next we have the roadkill Ubuntu computers. The laptop used in the production of the podcast is right behind the keyboard. To the right of the computers I have the HW-7 that we recently discussed. Next to it is my Ne-602-based 20 meter DSB transceiver. I plan to us the shelf above the HW-7 (where the clock is) for experimental rigs. To the right of the operating table I have some shelves that hold the beacon gear.

I have all the rigs on the operating table hooked up to an old MFJ coaxial switch, so it is easy to get them connected to the ether. I’m listening to 40 meter AM now. I did some Spanish language SW listening this morning: Radio Havana Cuba, Radio Marti, CBC Canada, Radio Japan, WWV…

Cleaning up proved very fruitful. I found an old portable DVD player — Elisa’s Mom now has a way of watching the many hours of family video that we have accumulated. I also found and rehabilitated some “family radio service” handi-talkies — the kids are using these to communicate with friends across the street. And I dusted off my old 2 meter Radio Shack HT. It works! I almost clipped it onto my belt as we were heading out today, but my kids would never allow me to be so techno-retro in public.

FIGHT ENTROPY!

A Blast from the Past: THE HAMMARLUND HQ-100

I’m sitting here in the shack at 0645 EST on the first Sunday morning in 2011. Coffee is on. And so is my OLD Hammarlund HQ-100. I have it tuned to a friendly AM roundtable on 75 meters. And it sounds GREAT. Nothing like a receiver that is as broad as a barn door to let you appreciate that great AM sound.

This receiver and I have some history. I bought it in the Dominican Republic, probably in 1993, probably from my friend (now SK) Pericles Perdomo. It had suffered the ravages of the Dominican radio environment from both ends: I think I found signs of a lightning surge at the front end, and of a power surge at the AC input. The audio output transformer was bad also. This was one of my first tube-type renovation project. I had a lot of fun with it.

There are no crystal filters in this receiver. If you want to narrow it down, there is a Q-multiplier (so –yikes!– this receiver is at least in part a regen). In its original configuration the Q multiplier doubled at the BFO, but I guess my anti-regen feelings were at work even then: I took the 100 kc crystal calibrator and put a 453.5 kc crystal in there — so that calibrator now serves as the BFO. This seems much more civilized.

You can see in the picture that the clock is gone. Mine was in pretty sad shape when I got it. Plus I thought it looked kind of goofy in that otherwise very beautiful front panel. So I took the clock out, patched the hole, and gave the clock to a very grateful Hammarlund collector.

The AM really sounds great. I can see that I’m going to need a 75 meter dipole so I can match this receiver up with my DX-60 VF-1 combo.
