Re: FT-243 FUN!

What I would like to know is how Leo Meyerson was able to turn a drill press into a lapping machine.  As mentioned keeping the sides flat and parallel are key.  I could never do it.  Could grind maybe 5 khc with finger and etch around 20 khz.  I read quartz has different density in different areas.  Consequently I think the finger method makes the crystal grind differently in different areas of the crystal.  Good luck for those wanting to try.  The only way I would ever attempt doing it again would be use a lapping machine.

4Staters,

Many years ago, I hung out with a couple of pals, Darell WA3OPY & Ron AC5UR, who both worked at ICM. Darell was their crystal engineer and Ron was his right hand man. I was working with QCMs (Quartz Crystal Microbalance) where we slathered bare quartz crystals with a patented glue and stuck compounds on top of the crystal. Then we put it into a holder of my design and pumped water over the crystal face. Specific contaminents in the water would bind to the compounds and change the crystal frequency. We could then determine the contamination level by how fast the frequency changed. That was another life back in the engineering world many moons ago....but it fueled my interest in quartz crystals. Darell, Ron & I hosted a workshop at Ozarkcon in Joplin Mo. where we showed how you can take a 'worthless' 6900+ military surplus FT-243 crystal and grind it to 7030. The 7030 frequency was just recently (at that time) declared a QRP frequency of activity and nobody had any crystals then. I designed a little crystal oscillator and measuring technique for the workshop where we could oscillate & measure the frequency of the quartz slab without having to put it back into the FT-243 holder each time you wanted to check your progress. I seem to remember we had about 35 QRPers all grinding away and every one came out with a working 40m FT-243 crystal...

That whole process was updated and used for my FDIM Buildathon in 2017 but I added a direct display frequency counter to the oscillator to replace the frequency counters we had to round up way back when. That design was recently reviewed by none other than Bob Allison WB1GCM in the ARRL lab and written up in the November issue of QST. All hell broke out and I was kitting & shipping the X-CHECKer kits for 2 months. I finally caught up to the end of the list leaving me little time to much of anything else. Along the way, I redesigned the board one more time to make the kit a little easier to use. So there are lots more hams out there having lots of FUN grinding crystals.

The other point of this email is to let everyone know that I now have a decent supply of brand spanking new FT-243 crystal blanks that make grinding a custom FT-243 for the 40m band a breeze. I would wager that Im the only one in the world silly (or stupid?) enough to track down someone who is silly enough too (to listen to me) and make me FT-243 crystal blanks! I invested an entire SS payment to stock my shelves with another crazy item. These crystals are in the rectangular FT-243 form factor, AT cut and are pre-ground for 7015 +/- 1000ppm which makes them run between 7008 and 7023  so they are already in the 40m band to start. I've ground one successfully up to 7218 so they are easily ground to any 40m QRP frequency of interest. They make putting a vintage rig anywhere on 40m pretty easy. I probably bought too many but I had to in order to get the price down to a reasonable selling price. I have a 3 pack on my parts page for $22 + $3 S&H so you could turn 3 junque FT-243 holders into 3 nice 40m FT-243s on your favorite 40m frequencies for $25.

Hello again :)
I have a bunch 
Like 10 pounds worth of ft-171-b crystals !
Brand new
Uncle Sam really liked crystals !
I would like to know how much uncle Sam spent :)
Likely all ft 242 and the whole assortment of others were made during ww2
certainly do not know why anyone would want to try to reproduce a brand-new Crystal blanks
Uncle Sam made them by the barrel. During the war :)
He spared no expense !
The only trouble is !

Field Day 2019

Charles W. Powell
 

There has been some discussion regarding a Field Day effort for the 4-State club, such as it is.  So far, the only standing suggestion is for Weston Bend State Park, just across the river for Leavenworth KS on the Missouri side.  Bert, N0YJ says he and Johnny ACØBQ have operated there before and it has some attractive qualities.  There are lots of trees and it is on relatively high ground.  I think this is a good choice. If anyone has other ideas, please make your recommendation known.  So far, we have three operators on board.  

I would like to collect names of folks who are interested, so please reply and let me know so I can start a list.  From there we can start to make some decisions about how many transmitters, what bands to operate, and exactly what kind of effort this should be.   We can make this casual, intense, or a combination of both.  I'm all for having fun, having some good burgers, AND racking up a few point.

We should eventually make some decisions on what kind of logging to do, if we need networking (I have some mesh network nodes we can use) and the like.  If we use computer control of the rigs, then the computers must also work on battery power (to be "legal" as battery class.)

So, please forward your ideas and let us know if you want to or plant to participate.

If you meant the solder sucker, Brian, the one I recommended works well enough to successfully remove 14 pin ICs ( with some final help from a heat gun) and leave the holes clean when you put the correct component in place.  Those little Radio Shack jobs were toys by comparison.

:)
I bet that is a really good book !
I would really like to read that !
I have always had a fascination with crystals !
Lots of crystals have the the month and year they were made !
I have some that have tape and in writing different military bases names on them !
Boy oh boy ! 
Just think of some of the communications that might have been made with those crystals :)
I was saying !
The trouble is !
I have a hard time explaining what I think !
We seem to be losing a lot of the history that has to do with the crystals we use !
Also I have some crystals made for interesting frequencies !
Like 5000 kc for instance :)
I really wonder what we were doing there then ??
Nevertheless Uncle Sam wanted his fighting men to have the ability to transmit !!!
In have/had a uncle who was a airborne radio op during the war !
The stories he would tell !
He was not a big fan of the vintage equipment though !
He would talk of the drift !
He was really a fan of the more modern equipment !
He also really liked SSB 
I feel he had the right to though  !
He payed his dues with a heated suit and a cw key strapped to his leg :)
One more last bit of fodder !
I have not seen much that stands the test of time as a wartime crystal !
The ones I have opened were actually shiny inside !
After 70 years and still perfect !
A ft 243 crystal is really a quality product of the United States !

seeking variable cap drive pulley (dial cord system)

Greetings folks
I am updating an old Meissner morale Rx that has a teeny cap drive pulley ... about 1.5 inch diameter. Ok for bc but makes tuning sw very touchy. I want to replace that with a three inch pulley, .25 inch shaft. Then with my aux bfo I could tune 4state  cw on a ww 2 Yeah, I know it is impractical.... think of it as performance art. The fun is in fabricating it then seeing that it works.

Does anyone have one, or know of a source (maybe science fair, or hobby robots suppliers, or surplus guys)?

Greetings,

Could this part be 3D printed? I do not have a printer, but always thought if some had a service to print parts they could pay for the printer in a short amount of time. This would be a small income maker for a retired person.

Just a thought, Jeff K9JP

Sounds like a plan!
We will need two adjoining camp sites so we can stretch out our antennas.
I remember some that were on top of the ridge that has really nice Tree’s

Count me in Chas, and thanking you for planning it this far ahead.  I operated there once with Johnny and Bert and there are some very good sites. I'll use my ATS4 powered by a LiPO

Probably have to register waay in advance, like January. There are some nice roomy, and high sites.

There has been some discussion regarding a Field Day effort for the 4-State club, such as it is.  So far, the only standing suggestion is for Weston Bend State Park, just across the river for Leavenworth KS on the Missouri side.  Bert, N0YJ says he and Johnny ACØBQ have operated there before and it has some attractive qualities.  There are lots of trees and it is on relatively high ground.  I think this is a good choice. If anyone has other ideas, please make your recommendation known.  So far, we have three operators on board.  

I would like to collect names of folks who are interested, so please reply and let me know so I can start a list.  From there we can start to make some decisions about how many transmitters, what bands to operate, and exactly what kind of effort this should be.   We can make this casual, intense, or a combination of both.  I'm all for having fun, having some good burgers, AND racking up a few point.

We should eventually make some decisions on what kind of logging to do, if we need networking (I have some mesh network nodes we can use) and the like.  If we use computer control of the rigs, then the computers must also work on battery power (to be "legal" as battery class.)

So, please forward your ideas and let us know if you want to or plant to participate.

72,

Re: seeking variable cap drive pulley (dial cord system)

Kenneth, try Google!
I found this ad for 2 caps with pulleys.
Also looked at Gilbert erector set parts and pulleys. Found lots of pulleys, wheels, and gears for shafts.
If all else fails, and you don't care about visable beauty, build a pulley out of a detergent container lid or medicine bottle cap. I made one about 65 years ago by soldering 2 Mason jar lids (without the rings) back to back. The drive string fit perfectly in the groove.
Punched a hole with a large Phillips screwdriver which left the flutes, forced it on the cap shaft and glued it.
When I was 14 and became a ham, if you didn't have it, couldn't find it, you built it!
It's still fun!
Cheers,

Could this part be 3D printed? I do not have a printer, but always thought if some had a service to print parts they could pay for the printer in a short amount of time. This would be a small income maker for a retired person.

Just a thought, Jeff K9JP

I am updating an old Meissner morale Rx that has a teeny cap drive pulley ... about 1.5 inch diameter. Ok for bc but makes tuning sw very touchy. I want to replace that with a three inch pulley, .25 inch shaft. Then with my aux bfo I could tune 4state  cw on a ww 2 Yeah, I know it is impractical.... think of it as performance art. The fun is in fabricating it then seeing that it works.

Does anyone have one, or know of a source (maybe science fair, or hobby robots suppliers, or surplus guys)?

Yes, that part could probably be 3D printed.  I would be happy to do so if someone could provide precise dimensions.  It gets difficult visualizing the possible combinations without actually seeing a similar part.    How wide can it be?  Is the shaft long enough to support a set-screw nub?  Does it need a v for a belt or a slot for a string?  How thick a string.  Once someone had the dimensions and designed and printed a part that actually works...  it could be posted on Thingiverse for any one to download and print.

Anyway, I would try if all those questions get answered.

Absolutely we should plan on using the club call.
