Activating AL-0001 with the QMX - and a bit of drone flying

Last year, Hans G0UPL rushed me a QMX at my request so that I could operate during an impromptu trip to Vietnam. As it turned out, it was impossible to get permission to operate and I've felt guilty ever since at having taken advantage of Hans' willingness to expedite the QMX.

But as of today the QMX has finally gone on a bit of a DXpedition.

I am currently near Theth Albania and have just returned from activating the unpronounceable-by-me Alpet e Shqipërisë National Park with the QMX.

The entire operation was on 20m CW. I was surrounded by mountains but was able to easily work a good number of Europeans and one US station (K2UPD) in New York. 

The QMX performed well.

I hope to activate the same park from another (better) location tomorrow.

Video: QDX-M assists in the rescue of a spelunker

The low-frequency capability of Hans G0UPL's QDX-M proved its worth in Alberta last week.

Rescuers attempting to retrieve a cave explorer made use of a QDX-M built for the 2200 meter band (136 kHz) which, evidently, will allow communications through solid rock.

The rescue was successful and can be read about here:

According to Hans:

"There is a request to make the QDX-M firmware operational down to 88 kHz which is where the UK and European cave rescue services have an allocation. I will try to get that done in the next week or two.

5-band QMX on this morning's 5-band POTA activation

The little QMX has come a long way since it was first released as a CW/digital transceiver, and I don't just mean the addition of SSB.

Far more significant to me are the very recent firmware updates that corrected two major shortcomings with the radio:

Strict DC input voltage limitations and

Common failure of the final BS170's during high SWR at full power.

These two issues prevented the QMX (and QMX+) from being a serious consideration for outdoor ops who don't use resonant antennas and don't want to take along a buck converter, LiPo battery or place "dropping diodes" in series with the DC source.

Those are a lot of things to contend with if you want to just set up and be on the air with minimal fuss.

They are no real issue at all though, if you don't mind taking the time to accommodate the radio rather than have the radio accommodate you.

Sometimes I like to savor the steps necessary to put a station on the air and don't mind taking extra time (and steps) to enjoy the process.

But for a roadtrip like the one I have planned, I want a minimal to-do list and a quick set up time - and I'm happy to say that the QMX/QMX+ now support this.

This morning's was my first activation with the 15-40m QMX. Hans built this one for me and expedited it to me a few months ago as I was trying to get permission to operate in Vietnam and Thailand. Thailand said 'Yes" but Vietnam said "No, don't even bring a radio here". So I had to leave the radio at home since VN was our first stop.

Now, with a different type of trip on the horizon, the little QMX again has become the front runner of the 4 radios I'm considering. 

Video: As much DX as domestic! POTA with the QMX+

The Crystal River area of west-central Florida contains several POTA sites within a small area. Crystal River Preserve State Park is my favorite for activations due to the covered picnic table and proximity to manatee-rich waterways.

Kayaks can be rented at the park but my purpose today was to exercise the QMX+ on the high bands and the bands did not disappoint. Contacts were made on all 5 bands 10-20 meters, including a good amount of EU DX and one station in Chile.

Several people have told me that previous videos that include text overlays of the callsigns being heard are helpful so I've included those in the video below. CW speed of myself and most callers is around 22 wpm.

QRP rigs, pricing, and what's missing from most of them

A search of the mythical Ideal QRP Travel Rig For Vibration-Rich Environments has me, once again, pondering what's out there and coming to the same old conclusion:

That the Elecraft KX2 - manyyears (yes, one word) after its introduction - still has no peer. Eight years old now - a virtual eternity.

Like others, I watch the YouTube infomercials of the latest offerings, hoping to find my unicorn. But lately, rather than compelling me to open my wallet, they reaffirm the value of the radio released back in 2016.

Here's where I'm coming from vs. what's out there - a bit of a backstory (please bear with me):

Nine years ago, I rode most of the off-road motorcycle trail known as the TAT that stretched (at the time - it's longer now) from Tennessee to Oregon, on a single-cylinder Suzuki DR650. Single-cylinder bikes are often called "thumpers" for good reason. I made it to Utah before the obligations of still being employed called me home. That fact bugs me like you have no idea. I almost finished - but didn't.

I had two radios with me: an MTR-3 and an Elecraft KX2. Both performed admirably and survived single-cylinder vibration and the bike being dropped three times on Colorado's Ophir Pass.

A few thoughts on the QMX transceiver

 

A recent get-together of Central Florida POTA ops, led, of course, by Bill N4NYM, allowed me the opportunity of meeting a dozen or so kindred spirits at Lake Louisa State Park where I very much enjoyed seeing their set-ups and eating their food.

One of those in attendance was a newbie CW op, Glenn KO4NTA, and somehow Glenn and I got to talking about QRP. He had several rigs with him but the radio he most wanted to show me was his new Army-green (tr)uSDX.

"It costs about $100, covers 5 bands and is super tiny!"

That very statement - since it applies equally - got me to thinking about my inbound QMX, and I asked Glenn if he'd heard of it.

To my surprise, he had not heard of QRP Labs at all.

At that point, I think I may have unwittingly become a bit of a salesman. Glenn had not yet been on the air with his (tr)uSDX and I had not yet been on the air with a QMX. I do have a (tr)uSDX though, and have made a number of hard-won contacts with it on both CW and SSB.

I know the shortcomings of the (tr)uSDX and, now that I've made almost 100 contacts (and two POTA activations) with my new QMX, I have a pretty good idea of where it stands in the $100-Rig Department.
