[Heath] Alignment Help Needed

[James Owen]

It's even easier than that Glen.  Simply connect the frequency counter to the output of the VFO or the output of the following buffer through a small capacitor.  Then set the VFO (either RX or TX) to 50 MHz and the frequency counter should read 8.333 MHz, tune the VFO to 54 MHz and the counter should read 9.000 MHz.  If not then adjust the proper cap or coil to bring it onto the frequency.  This will have to be done quite a few times to "walk" it on frequency.  Back when this was made very few Hams had a counter and I was one, though I had use of the ones at work.  Now about everybody has at least one, I think that I have seven or eight!

Easy, just use your frequency counter to read the frequency of your signal generator.  Then, use the signal, from the generator, to calibrate the VFO.

I have just finished rebuilding a Heathkit HW-10 Shawnee 6-meter AM radio.  I was able to align the receiver section without any problems.  However, in reading the VFO calibration and transmitter alignment procedures, I find that I don't have the proper equipment to do this as stated in the manual.  There are two possible routes to take, one using crystals for the low and high ends of the band and and another using a frequency meter.  I only have one crystal, 8.400 MHz. I don't have a frequency meter.  All I have is an RF signal generator, a VTVM and a frequency counter.  Is there another way to carry out these procedures possibly utilizing the equipment I have?
