Yaesu FRG-7 Short Wave Receiver

Here on my Tech Blog I really long to be on the cutting edge…..I like to discuss new technology, and how to exploit that technology.

But let’s make no doubt about it, I’m old school.

And I’m about to prove that once again.  Let’s face it, there were some things that were just done RIGHT that are old school.   Let’s list a couple of those things.

  • Film – Yep film cameras.  25 years from now all the computers and phones you have with all those millions of selfies on them will be in the landfill and you never really back anything up, do you?
  • Audio Equipment – I dare you to tell me to my face that your iPhone sounds better than my old tube amplifier gear with gigantic speakers that cost as much as my first car.  Nope the 70’s and 80’s were the golden age of sound.

And such it is with RADIO.  Oh yes they certainly do make state of the art receivers and Software Defined Radios with excellent selectivity and sensitivity.   But they are antiseptic at best, and void of the human condition.

As a little boy I was FASCINATED at the thought of dusk hitting and firing up the old Collins Short Wave receiver my fathers friend loaned me because he saw a future Ham  operator in me.  Putting on a set of headphones and spinning the poorly lit dial slowly and carefully at each and every blip outside of the normal static.

And so it is still ……………..

Yep you can listen to the BBC on your iPhone or computer but I can listen to it from Woofferton England replete with static and fading.  My signal is coming right from the UK right into my house in NC.  Is it as clear? No.  Is it sometimes frustrating. Yes.  Does it make me a little boy again?  You betcha.  Somewhere, somehow it touches the soul.  It connects with some part of that 13 year old boy in Indiana.  Can your iPhone do that?

And what an experience it is tuning the thing.   You don’t just tune.  THERE IS A PROCESS.  A process that requires, SKILL, finesse, patience, HEART.

 

  1.  Select the band for Tuning the Frequency Range you desire
  2. Set the MHz to the specific Frequency
  3. Tune the Preselector to match the band.
  4. Tune to a specific signal
  5. Observe signal strength.  Fiddle with 2, 3, and 4 until it is JUST RIGHT
  6. LISTEN.

Anyway,  The Yaesu FRG-7 is a legendary radio among Short Wave Receivers.  Was it the best?  Nope.  But I’ll tell you what it was.  It was that magic device that had just enough bells and whistles at an AFFORDABLE PRICE POINT that so many ham radio enthusiasts cut their teeth on.

It was hackable.  Yep, they did that back then only they called it “Modification” back then.  The receiver was made in the 70’s so I recall seeing these coming up and always wanting one.  They sold them in Sears and instead of having a gray case and a badge that said “Yaesu-Musen” it had a black case and said “Sears” on it.  Other than that it was the exact same radio.

Oh, how I wanted one.  But life is like that.   When you’re a little boy you can’t afford the $300 radio but when you are 56 you can and oddly enough it now costs more than $300.  That’s another good indicator that you’ve stumbled across that magic piece of hardware ………..when it is well sought after 40-50 years later.

The FRG-7 is built like a tank, is remarkably sensitive, and with the later inclusion of a Fine Tuning adjustment is quite selective, although you may have to tune off signal and use that Fine Tuning adjustment in a crowded frequency band.

So here’s a quick video of me toying with the FRG-7.  I hope you’ve enjoyed my nostalgia trip!

    What makes this an excellent receiver is that it used a Barlow-Wadley loop! Not a PLL circuit but an mathematical algorithm for stable frequency, cancelling out drift and signal drop outs! Rather than repeat, here is a link…. https://en.wikipedia.org/wiki/Wadley_loop
    Several receivers used this unique design including Yaesu, Racal, Drake and the Barlow-Wadley!
