How true, Tom. I put a side a lot of projects for my retirement and now that is here. I no sooner finishing one project when I'm prepping the operating table for the next patient. It is indeed a labor of love. I'm sure I talked to Andy at some time in the past. I will have to refer to my index card file, (that thing you would use prior to computers ruining the world!).  Wink

That is the most impressive collection of test equipment I have ever seen, including a classic Heathkit VTVM.

Hey guys, I have a bunch of Boat Anchors, to many in fact.  I am headed to Dayton Thurs and will be there by 6-7PM from Michigan.  will be there until Sunday morning, although we need to leave early Sunday morning. I can meet up with this stuff and save shipping.

I am happy to bring, but would like a little deposit to make sure we meet up.  If you see it and decide it's not what you thought it was, then I will refund your deposit.  I guess Paypal or something.  Here s what I have:

1. Johnson Viking Courier - $500 - Recapped, I had planned to use with my Ranger, but then I got a Valiant and just don't have enough room.  Has 866 tubes for rectifiers and 811's for the PA.

2. National NC-183D - $400 Recapped and working great. copy of manual I always wanted one and bought it from here last year or 2.  The dinged up cabinet drives me crazy.  Had a big thread here in the BA section over the winter.  https://forums.qrz.com/index.php?threads/nc-183d-trying-to-repair-i-am-stuck.851900/Turned out that there was a wire shorted out on the phono switch killing all the gain.  Has all new caps, and most all new resistors.  I put many, many hours into it, hence the higher price.

3. Hammarlund SP-400 Super Pro with Power supply and cable- $100 I have never powered it up.  Just never seem to get around to it, so I am open to letting it go.  It's in pretty nice shape.

4. Hammarlund HQ-160 - I started to recap it but it's missing all the tubes and shields.  I verified it has correct voltages.  I guess I just don't want to mess with it Front panel should clean up mice.  $50

Feel free to make offers.  Can meet at the Hamvention if you like or at my hotel in Fairborn.  I can take more pics if wanted.

If you want to talk, Message me and I will send you my number.

Here are the pics.

"Before Covid hit, Andy said to me on the air and on the landline that he WOULD fix one of
his Valiants and get it on the air!!"


Sounds like many of us who would rather fix, tinker, design and build stuff rather than talk and operate.

Look at his well appointed workshop (motivated to work on stuff) .....  compared to his lack of drive to get even one personal rig on the air.

He definately enjoyed working on and fixing stuff more.  His offers to test stuff for guys at the flea markets is just another form.  A little bit of that in us all.... Wink

Just like that legendary plumber who had leaky faucets, it seemed like Andy could not
manage to fix his own radios, and get on the air with some powah!!!

Before Covid hit, Andy said to me on the air and on the landline that he WOULD fix one of
his Valiants and get it on the air!!

It doesn't seem to make sense, but it does...

I'm researching voice characteristics and would like to get some input from willing ops who can monitor the asymmetry of their voices. Specifically, I'm trying to determine the percentages of those who have a consistent polarity (asymmetry is always in the same polarity regardless of speech) or have mixed polarity (where the asymmetry is different for lower vs higher vocal sounds).

In other words, are there moments where either the negative or positive modulation level drops even though the transmitter seems fully modulated? Lower vocal sounds "Aaaahhhh" and higher vocal sounds "Eeeeeee" can be 180 degrees apart, resulting in microphone polarity to be correct "mostly" but not "always". In this case, a low frequency equalization cut or boost can flip the dominant polarity of one's voice. It's quite fascinating.

A modulation monitor that can simultaneously display both negative and positive modulation would be ideal, but a look at either will reveal a drop when the asymmetry favors the opposite polarity.

I've seen all of this from a receiver, but audio processing and propagation will skew the results, so obtaining the characteristics at the transmitting end with processors set to "proof" (or bypassed) will be more accurate. Your input on this would be greatly appreciated!

Cell phune, one earphone, and one online SDR, and yer 1/2 way there.......

While at work, I listen all the time.


FWIW, my ear touched a 'dead' knob en tube wire one day. It was not a happy time.

What's really wrong, all previously mentioned aside, is, he's playing radio and I'm stuck here at work! Angry
