I've been staying in Tasmania this week, on the north coast, near Devonport and naturally I wanted to bring some sort of radio gear along. The QRP-Labs QMX recently added the ability to transmit sideband. I've had a few contacts with this and reports are good. The QMX (and QDX) are particularly good at FSK modes like WSPR I think due to the direct synthesis rather than audio mixing.
My travel case is quite small and fits everything I need including a pill bottle microphone.
The station was set up overlooking the ocean with a 29' wire pretty much just resting on some bushes.
Operation was on 40m at first but 20m was the standout. I was heard as far away as Europe in the first transmission.
I'm embaressed to admit that the very compact tuner was purchased from China and is clearly a copy of the QRP Guys' Ununtenna Plus. I have ordered the real thing which they say has much better quality toroids in it. The design is good and it's the most compact antenna tuner I can carry with me.
The QMX has a built in tuning mode with SWR display but I find nulling the LED on the tuner is easier.
At first I tried operating inside the house with the wire running out through a metal sliding glass door but I couldn't get it to tune. I think the close coupling to large metal earth threw things off. Operating outside was pleasant and signals were very good.
How did you go flying with 18650s? Did you attempt to take them carry-on or just inside the hold?
ReplyDeleteI chickened out and took a pack of NiMh AA cells which worked very well.
