For those of you that may have some trouble manipulating image files, here is the same schematic photo as sent earlier but oriented so that one would not have to use software functions to rotate the image for easier viewing.

RE:  programmable crystal IC/chip

I mentioned earlier about a QST article that used one in a 30 meter Whisper transmitter.  (that was the first incidence I remember hearing about them)

I have found the copy that I have. It is the January 2015 QST.  pages 47-50.  The schematic is on page 48.

Unless I am reading the spec sheet wrong for the current version of that chip, the pin out has changed.  The schematic shows the chip to be an 8 pin device but from what I can tell the current version is a 4 pin device.

It appears the device is a programmed (by DigiKey frequency specified by purchaser) Phase Locked Loop.

It appears that it requires 10ms max to "start up" and there is an enable pin.  I think, if I read it correctly, that a logic high = output on, logic low = output off

At a little over 4 dollars a unit (not including shipping) it will be worth ordering in my case and experimenting with.  I would like to see if a logic low/high could be used to "key" the programmable crystal and, if so, what does the waveform look like and how would it sound as a keyed oscillator.

I see that the transmitter in this article is using a 10K resistor to reduce the output level and a .01 uf capacitor for coupling and isolation of the chip into the oscillator input of the Gilbert Cell mixer (SA612) 

Sideband (double) generation is performed in the SA612 and later sent to the amplifier stages of the transmitter.

See photo of schematic included below.

Re: 60 Meter crystals needed

Well, I said phooey on Bomar and bought EPSON SGR-8002DC-PTM   crystal replacement oscillators from Digikey for $4.10 each.  They are super accurate (better than most crystals) and are direct replacements - except they need 5 volts to operate (no big deal).and won't plug into the crystal sockets, so one needs to make jumper cables to  to connect them to the crystal sockets.  I will put them in a small project box...probably use a 9 volt source with a resistor or regulator to get the needed 5 volts..That way I can use a 9 volt wall wart in the shack and 9volt battery in the field (back packing, SOTA, Field Day, etc.).  Current draw is so low that the battery should last quite a while, but  one can always carry spare 9 volt batteries in their pocket or back pack for extended portable operation.

Golly, I'll try anything before I will pay $45 each for crystals!!

Re: 60 Meter crystals needed

Back to the subject of 60 meter crystals:

Well, I tried Bomar Crystals Company for 60 meter crystals and they sent me an e-mail that they can make them, so I sent the an order for a quote on 2crystals each for channels 1, 2, & 3.  Here is the cost quote that I received from them:

****************************************

Please find below quotation for your review and approval.
Custom Radio Crystals for:
Homebrew QRP
Per your previous email you indicated as below
Load capacitance: 30 pF
XX = 30
Temp. range:  -10/+50C   = B
Tolerance:  30 PPM = E
Stability:  30 PPM = E
Mode:  Fundamental = 1 Qty: 2 each of
BCIEEB130-5.332000
BCIEEB130-5.348000
BCIEEB130-5.358500

Qty: 6
Unit price : $45.00
Lead time: 4 to 6 weeks

Please note our Minimum order is $100.00 or 2 xtals @ $50.00 each
plus Shipping via US Priority Mail is $10.00

**************************************

Since they are $45 each ($50 if I order only 2 because of minimum order being $100), the full set of 6 would slap me with a $270 bill (plus postage - probably still $10).

Since I don't have a money room like Scrooge McDuck, I will have to pass on the Bomar deal and keep searching for a crystal source with affordable prices.

Re: 4SQRP] 30 Meter Hilltopper Kit & More

I think that the problem with SMT kits will be in IDing the various components at the build stage. 

 I have only built a few projects that require SMT and got the hang of it quickly but at 77 I confess that my eyes are not quite what they used to be AND from what I’ve read some parts actually don’t have any ID on them so it’s difficult for the kitter and the kit builder.  Perhaps a dot of color and separate packages for caps and resistors ?

One does need some steady hands and eye assistance but the results are worth the effort.

as a club designing state-of-the-art SMDKits ?

OR BRINGING BACK KITTED things Like Norcal Sierra - NC-20/30/40

A new “ Build It Your Complete Kit Of Needed Bits “ to construct a small-footprint “ Bug “ !

Loads ! Of Options

I myself have put out the idea many a time for a club to do-things with the north ottawa qrp club ( micro model only ) touch-paddle

With things that could be added etc

Alas to no avail put down like a horse no longer required for the job

This is only thought on the SMD package but if folks had a lil’ smt tool supply along with their everyday soldering tools

Then kits would more requested & tried as the fear factor would deminish

Those were some great soldering tips Ron! Thanks! I wanted to tell you about a tip cleaner I discovered that works great. I saw the stuff they sell on Amazon that has steel wool in a snap closed container. Well, my 79 year old mom uses these things for scrubbing pots and dishes called Scotchbrite Stainless Steel Scrubbing Pads that are made from coarsely shredded stainless steel.  I took one of them and stuffed it down inside a small jelly jar and it works great for cleaning the tip on my iron. Just push it into it over and over 2-3 times and the tip looks like brand new!

Re: Soldering Iron Temperature

Great question, Woody!

   I'll toss my thoughts in the jar as well - should make the mud that much more rich! hihihi

   I use a Weller WES51 soldering iron with an analog temp dial on the front.  For SMD work from 1206 to 0403, and for through-hole assembly, I use 650° F and Radio Shack 62/36/2 silver bearing solder.  I sometimes have to take the temp to 700 or 750, or switch from a thin pencil to a larger chisel tip in order to attach parts to copper-fill grounds that don't have thermal relief pads.  I try to keep the heat to a 2 second count at most and will tweak the temp and/or the tip to keep that approximate rhythm.  

   I hope that's useful.

Questions for experienced builders who have a soldering station that allows the temperature of the tip to be adjusted.

For normal kit building, what  temperature do you generally use? (Fahrenheit please).

Are there specific tasks during the build when you increase, or decrease the temperature?  If so, in just a few words, what are they?

How hard, or easy is it to damage certain components or even the board if too hot? ...and what is too hot?

If your answers are reasonably short and would be of interest to others answer on list.  Also feel free to "Elmer me" off list.  I recently burned through a trace on a board that wasn't visible.  It was a challenge to isolate and fix the problem.... so, I need to learn.  Thanks / Woody / WD9F
