Re: QMX- High Power Output at 12 Volts?


 

¿ªÔÆÌåÓý

Hey Mike - I wouldn't worry too much about those readings - A lot of people have had similar numbers, see here. Also check out the It should be banned series of messages by searching the word "banned" in the search box. TLDR: I got on my first use of RWTST:

This is the third QMX I have built, each design improvement outperforming the last. Now on first powerup and testing RWTST on 12.00 volts I get the following output into a dummy load as per putty diagnostics:

40 meters 5.3 watts
30 meters 4.9 watts
20 meters 7.0 watts (amps went from .093 resting to 1.01 transmit)
80 meters 5.6 watts
60 meters 6.1 watts?

Per Hans advice I slightly spread the coils on L513 and got 20 meters down to between 6 and 7 watts. I have had over a thousand POTA contacts using this rig without problems.
