There are a lot of web sites on the Internet that deal with so called Boat Anchors - you know - old radio equipment full of tubes. If you are actually looking for boat anchors, try here. This site is quite different from most Boat Anchor sites. It deals with a specific models of some Boat Anchors that I own. It is also home of the BABE or Boat Anchor Beauty Evaluator.
If I did things right, there will be more than you ever wanted to know about the the Hammarlund HQ-215 receiver (well - at least I'll share with you everything I know).
Work in progress.
I recently "discovered" many BBOD's (Black Beauty Of Death capacitors) in my Hallicrafter SX-100. I will be replacing them soon just to be safe. For those not sure what BBOD's are, they are old style paper dielectric capacitors that have a common tendancy to fail by leaking heavily or shorting out. They sometimes cause other hard to find components (like I.F. transformers or filters) to fail as a result. Here is a list of the capacitors needed.
For those of you who are interested in the Hallicrafters SX-28 receiver, I have scanned an article from the May 1959 issue of CQ magazine titled "Updating the SX-28". There is good material in there on a great receiver.
An item mentioned in the above article is the S9'er, a method for improving sensitvity and reducing front end noise in older receivers. Here are the articles.
See pictures of dial cord used on a Heathkit SB-100. Someone requested this and I think I'll leave it here.
The Tektronix 7000 series oscilloscope was a very sucessful line that can now be an affordable hobby scope. Here is a list of plug-ins that work with the system.
Sometimes just a schematic is all that is needed to get something working. I'm going to put some schematics here for anyone who might need one. On my kits website, I have hundreds of schematics but they are applicable only to the kits featured on the site. Any overflow (i.e. not kits related) will go here.
New News Flash: A downloadable enhanced version of the BABE calculator has been developed. You will be able to run it on your PC even off-line. It does everthing the web version does plus it has built-in data for hundreds of Boat Anchors (475 on 9/26/06). You will be able to change the built-in parameters as well as enter new info. But wait - there's more. It also has built-in help. It can print a certificate. I had planned to make it available for download from this site but have not found the time to complete that task. If you want a copy, just email me. I wish I could say it was developed by popular demand. It was developed mostly by whim. What a deal. And yes it is free (as if I could sell it). Anybody out there? Anybody reading this? Wow, imagine what you would be getting if I got emails of encouragement!
The Collins R-390A receiver (a real and great boatanchor) uses an excellent PTO (Permeability Tuned Oscillator) as the master oscillator. There were a number of companies who made them. Although Cosmos is one of the more popular brands of PTOs, there were some other very rare manufacturers of PTOs. There were also some rare manufacturers of 807 tubes. Speaking of tubes, there was an ad on Craigslist that is hard to believe unless you see it.
How about a litle "more" humor?
Of course I have provided a list of links to other Boat Anchor sites. This list is far from complete but at least it will get you started (I know it did me).
Here is a link to email me. Now you can tell me what you think (gulp).
