Hi John and Terry,
    Several companies making PCBs will accept the files from ExpressPCB (Futurlec.com, Far Circuits, etc.).  Also, you can convert the ExpressPCB files to Gerber files using a program called Copper Connection.  Almost all board houses will accept Gerber files.

go to Expresspcb.com and you can download similar free software.  They have express_sch and express_pcb.  Both are very similar to each other in operation, except one makes schematics and the other makes PCB patterns.  While it doesn't give you digi-key part numbers, it does print out a bill of materials.  Also, once you design it, you can order the PCB from them (not free).  Another feature is you can link a schematic to your PCB design.  While designing the PCB, when you click a pin on a part, it highlights all the other parts/pins that pin is supposed to connect to. 

One advantage of the DIgikey software is, being web-based, it works with Linux as well as Windows.  The Express software only works on Windows. 

We're expecting a houseful of company tomorrow, so all my hobby stuff is temporarily put away.  It will come out again on Thursday.

Happy holidays, everyone!

Thanks for the heads-up Chuck, I did a quick calculation and it is WAAAAY cheaper than ExpressPCB for production.
I guess I can use some of my "downtime" to get some board designs finished.

Re: Frequency adjustment on a simple cw transmitter

James Compton
 

Chuck,
Thanks!  That's exactly the information I needed.  I ordered some of the polivaricon capacitor kits from Rex Harper at qrpme.com about a month ago, but he's been busy assembling kits for the Rockmite II and fighting snow on his farm near Limerick, ME so has been a little slow filling orders.  
I was certain someone in 4SQRP would know the answer to this question, since your net is on 7122 and getting the frequency nailed with homebrew rigs and purchased kits has to take some tweaking.
Thanks, again and Merry Christmas!

Jim,

The lower frequency is typical of the Rock-mights too.

In most circuits with parallel resonant crystals, a series
capacitor/trimmer will raise the frequency. An inductor in series
will lower the frequency.

Series resonant crystals such as the 7114s from ESS will be higher
than the marked frequecy.

A combination of trimmer and inductor in series can be arranged to
both raise and lower the frqeuency.

There are examples of such circuits in the W1FB's QRP Notebooks and in EMRFD.

Frequency adjustment on a simple cw transmitter

James Compton
 

I have recently built several QRP cw transmitters, all based on Lew Smith's Simple 17  meter QRP Transmitter design, but in different bands.  Without exception, the transmitting frequency of all of them has been between 1 - 2 kHz below the crystal frequency.  Adding a capacitor to the circuit, either in series or parallel with the crystal will supposedly change the frequency, as will a trimmer/variable capacitor (as in Simple Simon VXO) but I don't know if it be changed either up or down. 

My latest build for 15 meters uses a 21.060 crystal and the output frequency of the transmitter is 21.048.  I can and will experiment with capacitors, but it would help knowing where to start.

 My question: does anyone know where in the circuit to add capacitance to raise the final frequency? .....or lower it for that matter. Or is there an alternative method, such as changing the two filter coils?  Adding a capacitor would be simpler, if that would work.
