Re: QMX+ V2 - I've killed it
|
Hi all
My QMX and QMX+ here go through a huge number of experiments and a lot of abuse, and I don't see SMPS failures.?
On Friday Muhsin TA1MHS and another friend and I did some portable operating with my 80-20m QMX, I used an 8x Alkaline AA battery pack, and a short 2.6m telescopic whip with tunable sliding loading coil. There was a coax fault (open) and once we realized, we had to plug the whip directly I to the QMX. There was a faulty intermittent battery connection too which kept rebooting the QMX as it wobbled about, unless you could keep it still... which was hard when the whip was attached directly to the QMX BNC. We also tried a power bank having 12V output which didn't work at first but seemed to later sometimes work somehow.. Despite all these limitations and abuse (intermittent power connection, open load, high SWR) there wasn't any failure of any sort, and I made a few CW QSOs.?
In my?opinion the QMX/QMX+ probably aren't invincible but neither are they *that* delicate either.
