Minimalist Radio: A Lesson in Efficiency

One of the early posts on this blog was an article on "What Kind of QRP'er Are You", one of the categories identified in the article was the minimalist, i.e., the smaller, the lighter, the better. At some point being a real "Minimalist" becomes an art form that requires not only ingenuity, but also imagination. You can't always buy true minimalist equipment. Sure you can buy smaller rather than bigger gear, but at some point, without imagaination, you reach a wall that only  creativity can breach.

Recently I took a trip to Santa Fe, NM. I had never been to Santa Fe and had heard what a great place it was so my wife and I wanted to experience the city for ourselves. Also there are some nice SOTA summits in the area that I wanted to tackle  having become a SOTA addict. In my brief planning for the trip I contacted Fred, KT5X, who lives there to ask his advice on what summits might be doable for a relatively fit flatlander. Fred offered not only his advice but also his willingness to serve as a guide on the first summit. Eventually he recruited John, K1JD, a recently transplanted Santa Fe resident to come along. It was this trip that I learned what minimalism is all about.

I had a normal size day pack filled to brim with redundant equipment, two radios (ATS-4B, MTR), two antennas (vertical, EFHW), you get the picture, redundant but not a huge load. I will defend some of the redundancy in that I have limited time and don't want to miss an opportunity to activate a summit because of some equipment failure. Fred shows up with basically a camal back water pack that has a front pocket on it. A small carbon fiber pole that collapses down to 21" and extends to 21 feet, a resonant antenna and a home brew enclosure for his MTR that contains a key, power supply, logging pen and serves as an operating desk to log QSO's with. Fred's total set up is around 1.5 lbs. The MTR Board is designed fit in an Altoids tin to give a perspective on the size of the enclosure.

The key, a micro key,  is in the upper left hand corner and is retractable for transport and extended during operation. It is labeled WS0TA, a SOTA club call. The battery is a LiPo 500 mAH battery that will handle multiple activations due to the low power drain of the MTR. The logging pen is a Space Pen and has a string attached to keep it within reach and it sits in a straw holder, the red tube in the middle of the enclosure, when not in use.

To log, simply close the enclosure and log on a 3" x 5" card using the Space Pen. Brilliant.

Needless to say, when seeing what Fred was carrying to the top of the mountain I felt a little over dressed. However it was a great lesson in what minimalism is all about. In the mountains the fewer pounds you can carry, the more enjoyable the day. I have begun the downsizing of my equipment list and have been motivating to try a little creativity rather than just use it out of the box.

It was one of those CQs you don’t expect to be answered… (and trouble in the FT8900 PA)

If you’re a VHF/UHF enthusiast, you’ll know what I mean when I say that there are CQs you make, which you don’t expect to be answered.

And so it was last night, around 2030 local time as I was driving back from the gym to home. I knew that 50MHz had been lively earlier on the evening as I heard a CT station on FM as I drove up from the station. As I drove out of the gym, I could hear a local QSO (local to Italy, that is, with no callsigns) fading up and down on 50.500.

I wondered if the band was still open – so as I drove out along the main road, I tried a CQ call on 51.510 – completely expecting silence to be the only reply. But there was a signal – which completely caught me by surprise with its’ strength – but I didn’t have the volume set right. I thought it was a local and asked for a repeat. It was EA2DVT!

Although Alejandro was obviously having some problems copying me, we were able to have a nice QSO as I drove home. A real surprise and pleasure!

The FT8900 seems to have a bit of an intermittent fault though. A few times recently, I have had reports of interference on the audio. Baz, G8DOR thought it was something to do with the PA. The issue seems to be temperature related and only seems to happen for a short time. The suggestion seems to be that there might be a dry joint somewhere in the PA. It will be interesting to see if it occurs on both sides of the radio (the FT8900 having two distinct radios in it) – at the moment, I’ve been using the right hand side. I’ll switch it over to the left and see if that changes things.

Interesting

Tomorrow should be interesting. I don’t know if it’s just TV weatherman hype, out what, but I overheard the forecast for tomorrow, and I heard the possibility of three inches (7.5 cm) of rainfall.

So I stopped at Home Depot and picked up an old fashioned cylindrical type rain gauge. I installed it on the back deck, where it will be out in the open and not shielded in any way. It will be fun to see how much rain we actually get.

Sporadic on Six

Today there has been a really big Sporadic-E opening on 6m which lasted for several hours. In fact it is still going on as I type this.

This snapshot of activity from DXMaps gives an idea of what the opening was like at its peak. The whole of western Europe must have been covered by a reflective Sporadic-E cloud!

From DXMaps I could see that the opening extended up to 2m for a time, though I didn’t hear anything myself. Unfortunately my QTH is poor for VHF so conditions have to be exceptionally good for me to hear any 2m DX let alone work it. So 6 remains my favourite VHF band.

I made several 6m contacts on SSB and several on PSK31. The most interesting call was LY44WFF, a DXpedition to Klaipeda, Lithuania KO05oi which is quite a rare square so I’m told. Best DX on PSK31 was probably David, 5B4AHY.

I never quite know how to answer calls on 6m PSK31. Some operators seem to use quick, contest style operating while others reel out their name, QTH, EPC number and so on. I prefer the quick format myself, with the aim of getting the contact completed before the conditions fade out. But if someone wants to exchange a bit more information I try to do that too.

A station operating RTTY was an unwelcome presence among the PSK just above 50.250. One RTTY station came up right smack on top of someone operating PSK63. Surprisingly I got perfect copy of the PSK63 station which was straddled by the RTTY signal! Surely it is time to abandon this old, wide, slow outmoded mode?
