Topband: Sept 12 JT65 on 1838khz...nice opening to Eu.

[Lennart m]

I do not agree with you Pedro. More is not always better. Use no more than you need. JT65 allows more noise than does CW, thus one doesn’t need as much power.

Hi Jorge
Hi Jorge
JT65 is no diferent from CW or SSB, more power is better...use no more than 50% of your amplifier power, if you have an extra fan use it on top of your amplifier..
