Just read my post and realized I typed 4 feet, not 4 INCHES which it should be. The response should be: Bob, Do not change the tuning of the parasitic element at all. The gain and f/b is flat with the factory setting across the band. If you change the parasitic, chances are you will adversely affect bandwidth, gain and f/b. The amount of movement can be easily determined as the position of the jumpers is a linear function. If you have your jumpers at X position for the intended resonance, just move the driven element jumper 1" for every 25 kHz. change needed. If you are resonant at 7025 and want to resonate at 7120, move the jumpers (each of them) 4 INCHES toward the tips of the DE. Again, don't tweak the parasitic! 73 Natan W6XR/2 FORCE 12 East Ithaca, NY ----- Original Message ----- From: Natan Huffman To: F12Reflector ; BOB (AK6R) Sent: Saturday, February 26, 2000 10:07 AM Subject: Re: [Force 12 Talk] C4SXL 40M Phone Settings Bob, Do not change the tuning of the parasitic element at all.

The manual gives CW settings for jumper distance from boom for reflector and DE, but don't find the phone settings. Can anybody help? WOuld like to use in ARRL phone contest with transmit high and receive low. Need Reflector and DE jumper settings.
