[Elecraft] New Keying Bandwidth Mod manual available

[Martin]

Hello dear friend Tom (N0SS),
this is the first time, i completely disagree with you ;-)

I recorded a .wav-file of the keyclicks coming from my K2.

You can download it at http://home.vr-web.de/~hms/elecraft/

Decide for yourself, wether or not the mod is useful for a qrp-K2.

Listening to the .wav-file, you hear the zerobeat-signal, with the
dit-lever closed.
(caution: might be LOUD at the beginning). Then i move the RX-freq. upwards.
You hear the string of clicky dits.
You then hear 5 clicky dits, that ist 500hz up from zerobeat.
Next you hear 10 clicky dits, that is 1khz up from zerobeat.
Third, you hear 15 clicky dits, that is 1.5khz up from zerobeat (turn
the volume of your speakers up).

All this with only 2 Watts from K2 #2706, just enough to swing the
s-meter of my TS 850 (400hz Inrad-Filters in both I.F,s) to S9.
It is not a scientific method, IMO it is a real world method.

How often do you hear a 599+20db signal from a qrp-rig on , say, 80m?
Quite often, i think.

I will record a .wav-file as soon as my K2 has the mod.
It is on order already.

No, not at all...! In fact, it is probably MORE useful for those running 
QRO, as their clicks will probably be more of a problem to others than the 
clicks of a QRP station.
