That's great- reminds me of testing vacuum tubes in old TVs...

My Dad was a technician and had a lot of that old stuff that he still used.
Names like Halicrafters I believe, but cannot remember them for sure.
He's been gone for 23 years now. Curious, did you ever communicate with Hams in the Las Vegas area 20 some odd years ago?

Also like old Macintosh stereos, reel-to-reel tape decks and the accidental invention of rock by Marty Robbins due to a faulty mixing table's, "fuzz bass" ('Don't Worry About Me', it's all over now)...

My current project is this Hallicrafter sx100. It is a heavy receiver 40 pounds, so they are called Boat Anchors.

If you could possibly remember his call-sign I could search my logbook and check. I’ve been a ham for longer than that.

I remember it quite well. Sent to you via PM for privacy sake.

Crazy times- so surreal! Tehran is evacuating. Got a bike ride mañana.

24 minutes on the bike at 12.5 mph per hour equals 10,000 steps, walking. That translates to.... e.g., 5 mi. on the bike.

Yesterday, I was informed that my right shoulder needs replacement surgery, and is scheduled for July 24. I had a bike crash last May 28 that resulted in a fully torn rotator cuff and separation of the ac joint. The repair, previously repaired in 2011, has failed. The shoulder is badly out of alignment, pointing to the front and upward. I also had 2 fractured ribs and 3 fractures in my neck, C1 and C2. Ribs healed pretty quickly, neck was slow and doing okay now.

I am looking at the upcoming procedure as a step forward. I have been dealing with the very painful shoulder for over a year. At my age, I knew there was the risk of this occurring. I will permanently lose some mobility, but that has was already chronically limited. I need to lose the pain.

Guy I know well, age 69- still pretty fit and doing skilled trade work, fell off a roof. First time I ever heard the term, a 'broken muscle'. Operation is over and undoubtedly all went well but still... a long rehab time...

My worst bike accident was off-road. Not the first but definitely the last. Road bike only for me now but... it's definitely not free of danger! Head on a swivel but I figure that too may be a form of perhaps mental exercise for older dudes, no? On my ride, given grades and headwinds and recovery from numerous knee surgeries, average mph of 12 mph seems achievable but just slightly out of reach so.... there's a goal outside of just exercise. I've gotten close enough to where I figure, if I ever have a wind out of the West (which is the usual situation) but end up with a nice breeze out of the South for the return leg,.. I'll blow that avg. mph away!

Sorry for the crash, the year of pain, and for the interruption to your life. I have a purchased shoulder, but that was because of osteoarthritis. Best of luck with the surgery.

Last Ride before Back Fusion
 

I have been riding for about 50 years, now 83.
Today rode 35 miles with a bunch of mostly 30-40 year olds. 2000 feet of climbing. With an average 20 mph.
I do this ride on a Trek Domane+ and can use the small motor on climbs. I can now do rides I couldn’t do 12 years ago. I recommend an e pedal only bike for anyone who is old and still an active rider. It is good for fitness if you choose to ride hard enough.

71 and going strong. Dirt crits are a blast!

I'd like to address the most recent posters who either have had a crash or know someone who had a crash, resulting in major alterations to their cycling habits.

I'm 72 and I was forced (by health issues) to convert from riding two wheels to three wheels about 3+1/2 years ago. It was either that, or quit riding altogether. I can't afford to crash, but life without pedaling is not worth living. I have e-assist on my trike and it helps me keep up with my wife on her traditional bike. Since my conversion, I have put just under 11k miles on my trike odometer.

Honestly, I never thought I would ride a trike or need e-assist, but the money I've spent on my trike has been the best money I've ever spent. I normally ride paved roads, but changing my tires to knobbys and lowering the pressure let's me ride the more civilized gravel on Forest Service Roads and rail trails without much discomfort. There are trikes with more sophisticated suspension than mine has, for those who need it.

I'm guessing that most members of this forum would reject the need to get e-assist or convert to three wheels, but if your life situation changes, you may find a solution on the path that I've followed. I find the experience remarkably similar to pedaling a bike, and it's definitely better than not riding at all. That's just my opinion.

Well, exercise is about the best way to prevent or delay needing that change, but someday, I'm sure I'll follow in your path. Besides a sedentary life being simply awful, the mortality rates go way, way up for sedentary folks.

... it'd be fun to see Eddie Merckx (80) participate in the next TdF on an e-bike.

Yeah, and instead of handing him feed bags, he be getting batteries!

On the downside... time to change tires. On the bright side- all right...wore that sucker out! Time for a new Rubino.

Love the ride on this bike, and today - while riding - I remembered the wheels - and the bike they were previously on as an especially wonderful riding bicycle. Maybe the 27mm tubulars, maybe the rims/spokes, maybe coincidence? Hubs overhauled recently.

Post ride pic. The 6 pound weight gain over last few months is showing - in more than one way. BTW, I wore a helmet on the ride.

There's no way I'll fault anyone for riding a trike or e-bike. I don't want either one, but if the time comes when I can't ride a bike, either because of balance or strength,, I hope I can find the cash to buy something that allows me to get out and pedal.

Hmmm... I just read latest posts to this forum, then turned to check e-mail whereupon the first message I read featured a sponsor touting discounted, name brand e-bikes.

Any forumites here ever done business with an outfit going by the Upway name?

Despite being 76 I find I'm still enjoying battery-free biking (those powering my collection of electronic doodads notwithstanding) yet ever mindful that that may change.

How fast does this go? I had one of these sx100 years ago. I’m all sdr now. Enjoy the ride.

GILPI. In answer to your question. The pictures I posted were as i was taking the radio apart. There are 6 caps under the front cover so it needs to come off. I rebuilt many of these radios 35 years ago but the Hallicrafter s 96,100 and the 88 are very complex as there IF uses a very low 50hz for one stage. Not many rf generators go this low. Also the 100 is double conversion on all bands.. i changed out all the caps in less than 4 hours . You will need a tube checker as there are 14 tubes. I bought a cap kit from Hayseed online site. I do not have all the test equipment i need to do the the best it can be but i have it working and have been trying to find a RF gen that will cover the 50hz IF.

In the 1970's I worked at a company that tried to put all that circuitry onto a silicon chip. Took Intel many years, a sequential process of size, features, power/cooling, equipment technology, etc, etc. Exactly how many depends on who one asks. Late 70's were very exciting. i8080 was reported to be the 1st commercially available microprocessor on a chip. It was either the end of 1977 or early '78, when the processor went into the Finished Goods Final Inventory. My desk, specifically, and under a double lock and key.

wildwood i remember around 1955 i got my first transistor ck722 and built a radio around it. Also got my uncles track Paramount. I had bike shop add brakes to it and rode it for many years. Gave it to s friends son around 1980.

Early '60s.
My Dad was a Ham operator on occasion. Dabbled, never committed. Enabled I me and another kid start a 'radio station' in the basement. Our antenna ran up 3 stories and a bit more with the chimney extention.. Hilly area but in the correct direction we had power for 3 or 4 block range. Punch line is Mike Donegan went on to become a Nashville DJ. [He's probably not a cyclist] He would be about 74 years old now.

Dad was a smoking alcoholic, kinda burned out by the 4th kid. But if you got past the grumpy, smoky stink - he could teach you how to tune the car, build simple wood working things, or anything about the telephone system, etc. AT&T lifer (Western Electric).

I had one of the first IBM PC AT's... 1985!

And I have the perfect (still in its' plastic wrapper) IBM OS for your old computer. OS/2 Warp = the totally cool way to run your computer (unlike Apple, :), :innocent:, :roflmao2:)
