[HBR] Regen Birdies

[Ron Barlow via HBR]

Hi Bill,
 I recently learned that, at least under extraordinary conditions, regens actually can have birdie problems. I was using a hb regen, while listening to 160m. I was hearing legit 160m signals well enough, but I was puzzled by the fact that I was also hearing numerous CW signals below 1800 Khz.
 I discovered that the 2nd harmonic of the oscillating regen detector, was beating against incoming 80m signals, to yield audio output.
 This problem was greatly exacerbated by the fact that I was using an 80m dipole, as a receive antenna.
 As a result, the ~ 3.5 Mhz signals, that were delivered to the receiver, were actually much stronger than the desired ~ 1.75 Mhz signals.
 I made certain to use the 160m antenna, for receive, as well as xmit purposes, after that experience!
