> Some time ago we had a discussion on the list about the internally
> generated noise or hiss which is quite noticeable in the MP audio output.

> I designed and built a proto version of an 8 dB, 70.455 MHz amplifier
which
> gets inserted just prior to the second mixer to 8215 kHz.  The receiver
> gain is then reduced through menu item 9-1 to compensate.  The net result
> is a great reduction in the "hiss" and an improvement in the noise floor
of
> 2 to 4 dB.  Beta testing was done by N3RD and K3LR, both of whom are very
> enthusiastic about the results.  As a bonus, the audio filter peaking mod
> which K9AN came up with is included. 
> 
> A number of you emailed me and asked if you could obtain the mod if and
> when it was made into a product for International Radio.  The good news
is
> that it's now available and the bad news is that a computer crash has
> deleted all of my previous email records.  If anyone is interested,
please
> email the office at inrad@rosenet.net.
