I recently completed putting together my BitX40 kit.??The only
modification I made to it was substituting a 10K-10 turn potentiometer for
the original pot.??I obtained the kit last December and the original
sketch has NOT been replaced in the Raduino.

The time arrived to supply power to the kit.??As I did so, the kit came
alive with a few squeals, howls and ticking noises and then settled
down.??I had no indication on the display screen.??

So, I powered down and remembered that I had read in the forum to check
out the Raduino by removing it from the kit and powering it up with the
Arduino IDE program.??To make a long story short, I did that and the
display immediately came alive with a display.??I checked my wiring in the
kit and that was as it should be, i.e. the correct wires were hooked up to
the correct pins and all grounds were in place.??

I put back the Raduino into the case and hooked up the two connectors and
again applied power.??This time, the display lit up and the display ticked
up to 7.100 and remained there. There was no change in the display
frequency as I moved the tuning shaft. I powered down the unit and
unplugged the tuning control from the Raduino.??I checked the 10K pot for
resistance??and could see that it was operating correctly although it
seemed that I needed to reverse the outer wires, leaving the violet wire
connected to the wiper. (I changed the wire positions because the 1 turn
pot outside connections were reversed comparing it to the 10 turn pot.

When I powered it up, this time the display ticked DOWN to 6.999. Turning
the tuning shaft again resulted in no change to the displayed frequency.

In searching the forum for ?€?BitX40 tuning problems, I came up with a
posting written by Allard (for version 1.04) concerning the optional use
of a 10 turn tuning pot.??He writes that two lines of code in the sketch
need to be changed to allow smooth operation across the entire band.??

Is my failure to change those two lines of code the reason why I can?€?t
change the frequency on my display or are there are there other problems
that would cause this?

BTW, I do have adequate audio and a change in RF noise is very prominent
when I attach an antenna.

Thanks for any and all suggestions?€?.Keith -????AG??H
