Am I the only one noticing nasty spurs on the 6700 transmitter when using tune mode? 160M seems to be the only Band with a relatively clean carrier with much stronger spurs showing up on 30M and up with 17M being the worst on this particular 6700. (-95 dbm)
Tested 160-6 feeding the 6700 Ant1 into a Palstar5K dummy load. never show 100 watts out on this radio.... 85 watts seems to be the limit with a couple Bands getting to 80 watts only. Version is 0.13.10

ADDENDUM: Sorry... 6M appears to be the worst

Those are receiver aritifacts caused by high rf currents inside the radio getting into the ADC. They are NOT going out on the transmitted signal. The are simply not real Note that isolation decreases with increasing frequency so the artifacts will increase with frequency.

We could have blanked the panadapter as is done on other radios but we have decided not to do so. We like having the panadapters active while transmitting so that you can watch the bands with a second antenna.
