He might be working with ham hearsay.
I found that the talk back from my BC-610 xmtr was coming from the current
overload relay resetable on the front panel.
Once I bypassed the current relay with an oil cap the so called mod xfmr
talk buzz stopped.
There was an hints/kinks article on this also.
Try the xfmr elsewhere or temporarily jump the relay before cranking on the

Speaking for my friend, Perry/W5KGZ, he also likes Gary's work. Perry
recently acquired a modulation transformer for a BC-610 and while it
works great, there's a little problem of 'talk-back' from the transformer.
Perry was making noises this morning about taking the transformer out
and pulling the end-bells off, and 'really cranking down' on the bolts
that hold the laminations together.
