Topband: Palomar R-X Noise Bridge

[ZR]

Absolutely and I had the pleasure of meeting him and hear him speak.

Unfortunately his very public arguments with Warren Bruene in QEX and 
elsewhere over the "Conjugate Match" and then showing up on various forums 
to publicly push his last book as part of his legacy (which contains his 
final words on the subject with no further discussion) while the battle was 
still in progress was a bit dissapointing. Several tried to engage him in a 
discussion but he didnt want to be challenged and the subject was pulled out 
of respect for all the good he has done over his long career.
