SR-40 changes for Kenwood IF 8.830MHz


KD5NWA
 

I ordered a pair of crystals at three different frequencies close to the Kenwood IF. One set on the high side, two sets on the low side, inductors, and trimmer capacitors to see which one is the easiest to be able to park the SR-40 so I can look at +-10KHz on the Kenwood radio without getting signals close to the baseband.

When I get it figured out, I will let the list know which one worked the best, and we could then order a group buy.

I ordered the following crystals;

35.2512MHz, push this one 20.8KHz up, crystals are cheap, about $0.42 each
35.3037MHz, pull this one 28 KHz down, about $4 each
35.3280MHz, pull this one 56 KHz down, about $1.44 each

Stay tuned, same bat time, same bat channel, but hopefully a different bat frequency. Now where is that frequency counter?
