HALLICRAFTERS HURRICANE!

I was browsing some HIBID auctions, and I came across a beautiful-looking Hallicrafters Hurricane that appeared to be unmolested, so I bid on it.

I was winning at $100 until the end, but last-second bidders drove the price up into the $500 range. There was no power supply but I'm powering the receiver section as I write this with one of my Swan 117XC power supplies. UPDATE: I managed to get the transmit mode operational today using the 800-volt tap in the 117XC. Here is the auction ad and its pictures.

As I awaited the delivery, dark thoughts went through my mind. Would the 8122 tubes be in there? Would I find 20-30 cheap aftermarket parts like I found in the Collins, many of them simply tacked onto the leads from the old removed part? I won this for $475, but with the 25% "premium", and taxes and fees, I paid $583. Add in the $147 for shipping and the inflated priced double-boxes, and my total investment is $730. If the radio was adulterated, I would be out of luck since certain parts are super hard to find. It would go on eBay as "parts or not working" or I would part it out.

the radio arrives

The radio arrived, and it was unmolested. Everything was completely original. No golden screwdriver stuff. I took the bottom cover off and all the OEM parts were there. All the knobs turned freely and nothing was bent. I gave it a light dusting and tested all the tubes, including the 8122's. They are all Hallicrafters branded tubes and they're all good. I built an adapter to test the 8122s and a paper is below in the ADAPTERS section. The radio is really pretty, with the exception of a large scratch on the top of the bezel that looks like it happened at the auction house. It's dead center so if I can't find Hallicrafters grey touch up paint I'll find a cool sticker to put over it for now. I might even have some 1" x 2" metallic stickers with my call sign made up. Here are some actual pictures. 
The above photos are sort of self-explanatory. The power source with the big yellow Sprague Atom capacitors is one of my Swan 117XC supplies. I modified it to work with with the Hurricane and the 800+ volts provided by the 117XC provides enough juice to drive the Hurricane to a little over 200W PEP. I've already worked Japan, Australia, and other distant QTH's with my new baby.

Monster Hurricane Power Supply - It Works!

I finished my big power supply, and it works great! I'm working on a schematic diagram for it now. The power supply is literally two separate supplies in a single case, fed by a 12-gauge, 3-prong cord. Each transformer is a toroid made by Antek, with dual 115V primaries and dual full-voltage secondaries. The power switch for the high voltage section is a DPDT switch that switches the primaries between series and parallel, to switch between low (1000-1100 volts) and high voltage (2,000-2200 volts)  output. 

​Most of the time I use the Low Voltage mode, which yields a leisurely 300-350 watts PEP - more than enough to make contacts all over the planet. I get "great audio" reports. High power (photo below) bounces the power meter up over 600 watts which allows me to break through pileups easily. I still have a couple circuits to connect, but basically it's complete.

ADAPTERS

Test RF power tubes with a standard tube tester

HEY 19!

During my search for a replacement RF Plate choke, I submitted my serial number to a Hallicrafters expert and he identified it as the 19th Hurricane ever made. So it's "Hey 19". That explains something..

After I won the auction, a couple people approached me through Luther auctions to throw their hats into the ring in case I decided to sell it. One claimed it sat untouched in the top of a silent key's closet for 32 years but that's impossible. When I received it, it had two RCA 8122's in it, both with March 30,  2016 written on their bases. Someone obviously worked on it .

So it's somewhat rare. But I've been running it at lower voltages than the original power supply because I knew it was a 1966 model. At low power (1,000 volts), it produces about the same PEP as a Swan 500C, which is nothing to sneeze at. I worked Vostok base 700 kilometers into the interior of Antarctica with a similar rig, my Swan 700S. When I switch to 2,000 volts it produces 600 watts PEP. There's no reason to put 2,700 on it like the OEM power supply.

The plate choke burned because it was an early design with flaws.
