[TenTec] Noisy N4PY Chip in Paragon 585

[Alec Otulak]

Hi,

Has anybody experienced absolutely huge noise
which is being produced when N4PY upgrade chip
is installed ?

I am not asking about the noise whose existence
cannot be denied, but a possible cure which
perhaps can be administered to remove it ?

As far as I can see the noise is being produced
mainly by frequency/mode polling sequences. 
The moment the comport is closed the noise is 
substantially reduced.
When I checked and re-installed the original chip 
paragon was brought to its previous hush state of 
operation, so I am pretty sure where the glitch 
has been located.

Yours,
Alec/SP2EWQ
