Congratulations on the HT-40. I owned one years ago and it was one of the 
best li'l rigs Ive ever had the pleasure of using. I am almost embarrassed 
to suggest the obvious but I went through a similar thing with a Johnson 
Adventurer. Don't overlook the crystal, the crystal socket OR THE PINS ON 
THE CRYSTAL! (No kidding). I discovered , after re-capping that my chirp was 
being introduced by the 0.092 ferrule placed on the pins of my HC-6/U 
crystal. It was crimped tight enough and caused the chirp. Another rig gave 
me the same problem and I had to change out the crystal socket itself. I 
suppose wear, corrosion, finger oils etc can put a coating on the crystal to 
pin contact and act like a capacitor itself. Good luck and we will be 
listening for that HT+40!
