Hi Ken, The problem is typically of high current small loops and tuned matching circuits. Also, sunlight can heat up the coil and the variable capacitor and cause dimensions to shift and therefore the resonant frequency.
Tightening the spring is good. Putting a shaft lock on the shaft "might" help, but then you would forget to unlock and engage the motor leading to major problem. Keep the Loop cool and in the shade for less variation in tuning. Same for the capacitor housing. The wind might be an insurmountable problem unless you camp in lee of the wind areas, at least for the antenna, like set up with rock cliff protecting antenna from direct wind. 72, Stuart K5KVH _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
