Hey Bry, Your 2 crystals for the Drake 2-B did the trick! Working fine once again. Thanks for your super crystal service!

The 28.9-29.1 crystal arrived and works well in my 75S-1.  I'm using it to put the receiver on 10 AM.  Now all I need is some propagation!
Tnx & 73 Ray W2RS

Thank you for your very fast service! They all play. Anyone who asks about crystals I'll direct to you.

73 - Norm, NZ5L

The crystals arrived this morning in good order.  

For information: I plugged a pair into a BC-611 and checked transmit frequency for the 3870 crystals at 38700 with the Radio Shack pocket frequency counter.  Receive crystal also worked around 3870, but the receiver is quite broad pending alignment. 

The oscillator is a Pierce and you could calculate the load capacitance given by:  http://www.abracon.com/Support/facn_abracon_jul2011.pdf  but they are essentially right on as manufactured for this application.  Original crystals are usually within 300 Hz. 

Thanks for thinking of us West Coast AMI members on 3870.  Your crystals are perfect for this (low power) application.

Cliff, WB6BIH

Thanks, Bry - I don't want to be caught without crystals when conditions are good!

The ones you built for 3870, 3875 and 3880 are dead-on and run fine in my Globe Scout 680A. Someone commented "you're off-frequency" the other day. Turned out their VFO needed tweaking........ been complaining about my being off-frequency for months, hihi! Cain't beat a modern rock!

Treat them right and they'll treat you right. The trick, if you gotta call it that, is being gentle to them. Don't be a hot-rodder. The Oscillator's job is to oscillate. Use the Buffer and PA stages for what they were intended: AMPLIFICATION.

I would check with Bry Carling, AF4K. He sells lots of crystals, and would be the first guy I would check with, for them, if needed. I am sure his email is listed in the usual locations. He is honest, fair, and sells a good product, at a fair price. 

I have done 2 or 3 transactions with him, and he has always been a stand-up guy.

Brian Got my xtals in the mail today. Great packing job. They are A number one right on the money. Definitely a good investment for my Knight T- 60. I'm having a ball on AM and low power cw on 80 and 40 meters. Now I'm all set for SKN on Saturday.

Thanks and Happy New Year -

Hi Brian

Just wanted to let you know the crystals arrived yesterday and I am really pleased with them. Also wanted to comment on how fast and smooth the ordering process was online. I will be ordering again.

Thanks and 73

"Dear Mr. Carling, I recently received the three crystals I ordered from you and was very
pleased with them. Here is my order for two more that I need from the list
on your website. With the increased interest in vintage equipment, I think
you are providing a valuable service to the amateur radio community."

Bry,

Just returned from a trip and your shipment was waiting for me.  I’m very pleased with the meter and switch.  Thanks for the very good packing.

Chris

Hi again Bry,

Just wanted to let you know that I tested the tubes and they all made it through the gorillas that were in charge is getting it to me.

The 6146W's were very high on the meter and so close to each other that I would consider them to me a matched pair.

Thanks again!

The 3 crystals arrived and tested FB.  Many thanks, Ray W2RS

Brian,

The 23 crystals arrived in Waupun today on Friday. Look very good.

TKS much - Chuck

Hi Bry
I got the (Lafayette) HA600A today. VERY WELL PACKED! I have it on 20M now. In the next
couple of days, I plan on putting it on the bench to clean the controls. Might need
a little aligning, too.
Thanks for the quick turn-around and excellent packing.

Bry - The Drake 20.8 arrived today - very, very quick. Already installed and working fine.

All of my xmtrs use (your) FT-243 crystals...

 I now have enough QSL cards for my first DXCC award. I'm now
working on WAS QRP using the xtals and my two QRP xmtrs. One is a single
6AQ5 tube with about 2 watts output on 80 & 40 meters. This is a 'clone'
of my first Novice xmtr back in 1957. I used a Navy BC-455 40 meter rcvr
with it. That was my first Novice station in 1957..hi hi The other is a
nice restored HW-8 for 80/40/20 & 15 meters with about 2 watts output as
well. The other restored pair

I just worked a Japanese station on 40 meters CW on about 7010 early in
the morning after many many tries calling many Japanese stations that were
calling CQ over several day's and finally 'snagged' one using my HW-8!!
Not bad with 1.5 Watts and a Windom antenna..hi hi

Gil,W7JBJ

I unpacked the radio over the weekend, first chance I've had to do it. I
must say, you did an excellent job of ensuring that the radio would arrive
in flawless condition! Not only did you wrap the radio in plastic, then
bubble wrap and put it into an inner box lined with peanuts, you surrounded
THAT box in peanuts and packed it neatly into an outer box. Terrific!

Then, the radio was much, much nicer than I ever imagined it would be. For
a radio that graced my shack in about 1964--that's 30 years ago--the one I
purchased from you was in very good to excellent condition and made my
heart flutter. Seriously! Everything was exactly as you advertised it to
be, and I was not only NOT disappointed, I was thrilled that it was beyond
my expectations! And quite reasonably priced, too.

Of course, Fedex ground did a fantastic job delivering it on time and in
great shape. Thanks for providing me the tracking number and the email
updates as to its progress from Florida to California. The PayPal payment I
made to you was handled flawlessly and with no errors.

Just wanted to let you know that I appreciate your efforts, and I'll gladly
buy from you again.

I just wanted to tell you that I got on the air with my Globe Chief 90
this evening. I got this rig about a year ago and it was so covered in
dirt, I almost took a pass on it. I spent days cleaning the chassis,
etc. and finally got it running a week or so ago. Tonight I plugged in
one of your crystals and called CQ and had a QSO in just a few minutes.
I bet that's the first time that radio has been on the air in 40 years.
I had a great chat and I just wanted to say it wouldn't have been
possible without your crystal service.

Thanks for doing what you do! Here's a photo of my transmitter:

The 3413B and the ATR 12V vibrators arrived today in fine shape.  
You did a superb/professional job of packing.  It's really nice 
to receive a large package that is obviously so well-packed that 
you know the contents will be in fine shape -- even before you open 
it.  It really is nice to run across folks who take responsibility 
for the safe delivery of what they sell these days.

Thought I would hold off on comments until I did business with you a couple
of times....You are consistant with e-mails. The crystals i bought form you
are exactly as you said....The 6t9 based transmitter is perfect for my
ongoing project and the prices are right. Will continue to do business as
finances permit. AF4K is trustworthy.

Hi Brian,
Boy this is getting to be a habit! This is the 3rd crystal order 
I've sent you. I've passed the word on and you may have already
gotten an order from one of the locals. I use these crystals in
my old HT-40 I restored and in a homebrew 5763 QRP transmitter
I built. Kinda brings back the older days like when I first got
my novice ticket over 40 years ago.
Thanks and I am sure we will be doing more business.

Brian - Just wanted to let you know that my crystals arrived today.
 
They all work just great in my Knight T150.  They all produced a nice CW note and were right on frequency 
according to my TS440 digital readout.
 
I will spread the word to my fellow boat-anchor collectors/restorers/users.
Thanks for the great service!

Hi Brian - I just wanted to let you know that the Astro 103 radio and PSU-6 
power supply arrived safe and sound.  I'm very happy with the radio and 
thank you for selling it to me.  It is going to be a lot of fun.  I hope to 
work you sometime on the air.

Brian - thanks again for the great FT243 crystals! I'm very pleased with
them. The first thing I did was to plug one into the old Drake 2NT. 
It's so cool to see that old rig come to life again. I was dancing
around here like a little school boy. It's amazing what a little
excitement will do to get the rust out of the old' bones.

Anyhow. I've enclosed $21.00 for two more FT243 crystals. 
Please send one 7030 and one 7035 KC.

THANKS! - Ron Jewett, WA0RJ

Today, I received my crystal from Brian Carling, AF4K.  Brian has been
offering his crystals on his website:

http://AF4K.COM/crystals.htm

He custom mounted the crystal in a HC-6U holder and did a splendid job. 
It will go into my Collins 20V-3 so I can work AM on 1885 Khz this
Fall/Winter.

Thanks, Brian, for all your efforts.

Yesterday in the mail was a bubble cushioned envelope with my 
two new real FT-243 7040 Khz crystals from our buddy 
Brian Carling!  

Thanks Brian.  I just ordered them late last week and a few 
days later they are at the door.  

Looking at them, they are your typical brown plastic 
FT-243 case, they look like new cases too, clean, clearly 
labeled.  I'll try 'em out this weekend. I see Brian just 
put out another post for additional frequencies, so I'll 
be ordering some of them too.  

When was the last time you could order FT-243 crystals huh?
Nice job Brian!  

If I'm lucky, maybe 36 years from now I'll still be using 
my Brian Carling crystal :))

To plug a crystal into my Johnson Ranger you need fingers 
approximately the size of ET's, plus a flashlight to see what 
you are doing. 
But at least I don't have to do it often, I just stuck 3880 and
3885's in there (from Brian, of course) side by side, and slapped 
the cover back on. It's a novelty to turn on a Ranger and be able 
to talk on freq in about 3 or 4 minutes.

- Jerry Kincade, W5KP

Thanks for sending the crystal. A pleasant surprise; 

The column featuring a classic rig with crystals will be in 
October 2004 issue of CQ and I will tell folks to check with you 
on crystals. I am still drawing up the circuits and writing 
the article, but it is a rig you will love.
