Everybody who is involved in extreme narrowband mode such as QRSS and DFCW
will confirm that signals that are 10 to 20dB below the 'normal CW'
detectable level can still be copied and lead to a QSO.
OK, it takes about 30 minutes or more but this time period is accepted for
Meteor Scatter contact on VHF (I believe that the time limit for a valid
QSO is 2 hours for MS).
Nothing wrong with being a 'die hard' CW operator, but that is no reason
for  neglecting the fact that extreme narrowband modes are superior to
'normal speed' CW when it comes to signal to noise ratio. Both theory and
practise proves this.

Keep it SIMPLE all that is required is a good cw operator at each end with well filtered, selective symmetrical EARS able to read morse through qrn and qrm and a steady hand for sending.

There is none of this palaver required on the other bands so why 136 khz. CW

operators in Europe are working ZL and other dx locations frequently through qrn, qrm and other difficulties on 160 metres. The cw method is simple and

very

effective for those competent and experienced and very COST EFFECTIVE for

radio

amateur type of communications.
