Video of Tuner Genius XL in dueling CQ SO2R
At Field Day I decided to try SO2R with 10 and 6 meters. 6600m and Tuner Genius XL set up with two instances of WSJT-X and N1MM+ calling CQ on each band on alternate time cycles. (Dueling CQ).
That's just too cool!0
What is the SWR of the two antennas without the tuner inline?0
Ummmm when did you receive?
I get it it’s just a demo0
Very cool Dave! I can barely keep up with one QSO at a time...0
It was live, actually working stations. Radio in full duplex. One instance of WSJT-X on odd cycle TX and then other on even cycle TX. So when 10 meters was receiving six meters was transmitting and vice versa. Sunday morning both bands were open so I was able to rack up quite a few Qs.
5 element 6 meter beam was 1.4:1 and G5RV was 2.3:1 in bypass. I could have bypassed the tuner for six but left it in circuit.
There was no interaction between the bands. One leg of the G5RV was about 6 feet from the 6 meter Yagi.2
Great video/demo! With this arrangement I imagine the TX is close to 100% duty cycle minus the few seconds of silence between RX and TX on each cycle?
I need to do this and up my contact rates if I can handle the mental stress…lol
Yes, after 1/2 hour at 100 watts I started seeing the 6 meter power drop about 20 watts. I took a break to let the radio cool down and put a small fan pointed on an angle at back of radio.
Normally I’d be using the Power Genius so drive power will be lower.
SO2R does generate heat!
