Cool mics from my collection and ones I wish were

I like microphones.   I have lots of them, and lust after more!   I'll be featuring cool microphonia in the Gallery from time to time, so check back often!


   If, like me, you enjoy flipping through old issues of 73 magazine from the 60s, you're bound to have at least seen the ads for the Transcom SBT-3 three-band SSB tranceiver.  Being made in Escondido CA in the mid-60s, my guess has always been that engineers from other San Diego SSB compnanies such as Don Stoner, Les Earnshaw from Southcom, Herb Johnson, founder of Swan or Faust Gonsett may...  READ MORE

When he learned of undertakers’ difficulty in fastening neckties on corpses, the teen-age Lewyt devised a new kind of bow tie that clipped on. He sold 50,000 of t...  READ MORE

AN/GRC-9 Bias Battery replacement

Cheap and easy fix using coin cells
Category: Technical
The Korean-war vintage AN/GRC-9 is one of the most useful and fun military field radios for ham use, as with AM and CW modes and 2-12 MHz coverage and a VFO it's all ready to go on several ham bands.    The battery tube superhet receiver is also power-friendly and sensitive and stable enough to copy CW and SSB but has one annoying flaw - the 4 volt bias battery used by the audio...  READ MORE

Beware of the LED Noisemaker!

MR-16 lamps have no home in the hamshack!
Category: Technical
Halogen type MR-16 lamps are commonly used in track lights and other spot lighting applications so what would be cooler than to drop in LED replacements!   A lot, as it turns out.   The LED replacements are HORRIBLE RFI emitters that totally trashed several ham bands when I unknowingly installed them.Halogen spot lights are 12 volt devices so it's long been common prac...  READ MORE

   In the days before sat phones, HF SSB was the only practical means of communication once you went beyond line-of-sight distance from civilization.   Forestry crews, scientific exploration teams, mariners, and oil and gas or pipeline workers were among those for home HF SSB was a lifeline.  Portable transceivers like the JRC JSB-20 were used when moving from one location to another a...  READ MORE

   Like most people who received a catalog from International Crystal in the 60s, I was always intrigued by their assortment of PC board kits.   There were boards for every stage in a radio transmitter or receiver and they could be combined to make almost anything - from converters to complete radios.   But little did I know that International actually did just that when they went...  READ MORE
