Re: Are these output watt rating crazy?

I haven't had any luck on 160 meters so far due to a compromised antenna. But rest assured that I am using and external low pass filter that starts to rolloff a little above 2 MHz. The filters inside the radio are definitely *not* for 160 meters.

It hears pretty well on 160 for all I can tell:)

We've had a number of folks here who assumed it did, since the firmware allowed them to spin down and transmit on 1.8mhz.
The third harmonic of 1.8mhz at 5.4mhz will go out on the air almost as strong as the fundamental.
