["ALEX DELIGIANNIS" <sv8qg@otenet.gr>]

John,

        Thank you for the advice I'll try some profesonal preaplifiers like HP 462 or HP 465...

Till now I used an Yaesu FRG-100 with an external speaker sp-102 and I had very good audio from weak signals both in LW and MW.. also the Smeter all the time was above S3 with a 80m loop. With the IC-75 I have sharp audio not so pleasant and I can't use the preamplifier at all due to indermodulation and birdes... I'm leaving in a quet -from RF- Island and my only problem is QRN. Thanks for your message 73's ALEX from LESBOS Is KM39GC

Alex,

 

Personally, I'd leave it alone, unless you were really limited with your receiving antenna. I use a loop for LF receiving, and a 30 dB preamp. I leave the R-75 internal preamps off, as they pick up some "birdies" within the receiver. The resulting signal levels appear to be more than sufficient for serious LF work. This was the setup that I used last week to copy G3AQC on 73 kHz.

 

The R75 is a very nice receiver for the price, and one of my smarter buys.
