[Elecraft] K3 <> Hiel Proset

[Evert Bakker (PA2KW)]

Hello,

 

As this question is about peripherals, I don't know if it is allowed to, but
I give it a try. (if not let me know).

I bought (locally) a Heil-Proset with the HC4 element to use in combi with
the K3.

I used to have a 20 year old Telex (very tiny headphone, mono wired and no
microphone). I'm still very happy with it as its designed for
telecommunications use.

But with the KRX3 installed, it's time for the stereo set.

 

When I listen to stronger stations (more volume) it sounds like "clouds with
a silver line" where the silver line is a very distorted high frequency
product of the signal I'm listening to.

It's annoying and tiring. What can it be? Has this something to do with the
AF distortion in the K3 (SN0812 and SN2185, FW 2.78 / D1 1.98, D2 1.98 and
both the same effect) as was discussed earlier on the reflector.

 

Any idea?

 

Later tonight I'll get my Drake TR7 running again and see if the effect is
also there (I just guess not).

 

Thanks in advance
