Windows PC users now have the option to try yet another weak signal digital mode. Called V4, it is described as “a robust, easy to use, keyboard sound card mode that would fit into the narrow digital segments of our HF bands.” The mode is 200Hz wide and capable of sending text at 40 – 60 words per minute.

Do we need yet another keyboard digital mode? Although PSK31 is very popular and very narrow, performance deteriorates under conditions of multipath reception (such as in NVIS propagation) or when the ionosphere is disturbed (polar paths during periods of auroral activity) while RTTY, though also popular, is archaic, inefficient and successful only by brute force methods (a big amplifier and a beam.) More robust FSK modes such as MFSK, Olivia, Thor and DominoEX perform better but are much wider which can be a barrier to use. V4 uses the same robust modulation scheme as WINMOR but has been optimized for use as a keyboard chat mode. A detailed protocol description can be found here and the software can be obtained after joining the V4 Protocol Yahoo Group.

I have only just been admitted to the group so I have some reading to catch up on and it will be a few days before I can find the time to try V4 for myself. However I am quite interested in this mode which seems to have been developed by licensed hams keeping in mind the need for responsible band use (so no 2.2kHz wide signals!) and with all the details being published and open. The software modem has been implemented as a standalone TNC that can be interfaced with other applications such as my own program KComm which is also interesting to me. So I think you can expect to hear more about the V4 Protocol in this blog in the weeks to come.

Alex, G7KSE wrote recently about monitoring the International Beacon Project beacons on 20, 17, 15, 12 and 10 metres, which gave me the idea to try it again for myself. I did try the Faros beacon monitoring software by VE3NEA a few years ago but being a tightwad I never registered it so the trial came to an end after 30 days. I was also less than enthusiastic about leaving the computer and radio running every day 24/7. Work out the power consumption and it can add a significant amount to the quarterly bill which is unlikely to go unnoticed by the chancellor of the exchequer (the XYL.)

These days the computer is usually running from when I get up (or after breakfast) until when I go to bed in order to run my HF and VHF APRS gateways so it is no extra trouble to do some beacon monitoring as well. I don’t have a spare radio or antenna so I will have to use my main radio (my K3) and antenna for the beacon monitor. This means that if I want to go on the air the beacon monitoring will stop. Currently my enthusiasm for actually making contacts is at a very low ebb so this is not much of a problem. I shall still shut down at night and restart in the morning, at least during the winter months when there is no night time propagation on 20m and up. Apart from the pointless waste of joules, the loud click from the K3 each time Faros changes bands will be a disturbance as the shack is only just across the landing from our bedroom.

The antenna I am using is the short multiband 80plus2 dipole bent to fit into the roof space, with additional 10m and 6m elements. It works fine on 20, 15, 12 and 10m. On 17m I can get a good SWR with the aid of the K3’s built-in tuner (which is the source of the loud clicks) but performance is noticeably down on the magnetic loop. However, the magnetic loop is used by my K2 for the HF APRS gateway so it is not available.

VE3SUN has written a very good article explaining how to set up a system to display the beacon reception charts created by Faros on a web page. It looked easy so I went ahead and set up an IBP Beacon Reception page on G4ILO’s Shack. I found that the WinSCP software that VE3SUN recommends to automate the uploading of the reception charts to the website popped up annoying windows whenever it updates so I used SyncBack SE instead. Unlike WinSCP it isn’t free, but I had purchased a license a few years ago and the code still worked with the latest version.

I converted the JavaScript in VE3SUN’s example page to PHP. This means that I can test for the existence of the beacon monitor graphics and display a friendly message rather than have the browser display a “missing picture” graphic if the monitor has not been running and that day’s GIF image doesn’t exist.

I have added to the page a short list of currently active beacon monitors to make it easy to compare my reception reports with other people’s. It would be nice if, instead of each beacon monitor having his own results on his own web site, there was a central site that collated all the IBP reception reports and displayed them on a map, like WSPR does. Perhaps that would rejuvenate interest in the IBP which seems to have been overshadowed in recent years by WSPR and reverse beacons.

When Work Gets in the Way of Ham Radio

Every now and then we hit one of those seasons of life where our work gets in the way of our hobby. For the past month, seems like work has overtaken the time and my radios have sat idle for WAY TOO LONG.

Thankfully, this weekend brings some relief and our Central Florida QRP group will take to the outdoors for our monthly outing. No one will be able to complain about the weather being too hot either, as the northland has sent us a reminder of why we moved to Florida. When it gets below 55F we get cranky and it looks like it will barely go above that temperature this weekend.

So look out for us this Saturday, 11 December 2010 about 1500-2000 UTC on the QRP watering holes on 40m, 30m, 20m and who knows where else. We’ll be out there with rusty fists on the keys once again. YAHOO!

With the Es season just a distant memory, I’ve moved the 70MHz antenna from the FT847 onto the 70MHz FM rig, which is a converted Philips FM1000 PMR set. It seems to be working, though there are no QSOs to report just yet. I can hear the MB7UW packet node on 70.4875 some miles away and the GB3RAL beacon on 70.050 is loud! Test transmissions from the Wouxun handheld within the shack are loud too. So, hopefully there will be a QSO before long.

There’s a net in Swindon on a Friday night now, 2000z, run by John, G4SRE – starting off on 70.450 and moving to 70.475 – so should be able to work some of those guys, and there’s also some activity from Reading on, I think, a Tuesday night.

As 2010 comes down the final stretch, I’ve been reflecting on the past year and thinking about 2011.  This year I didn’t do as much operating as past years and I continue to struggle with keeping my interest going.  I don’t think I had a casual CW QSO all year and I haven’t homebrewed a thing.  I’m not sure why, but homebrewing just doesn’t hold the fascination it once did and it seems tedious.  But on the positive side, 6 meters was fun this year during the sporadic E season, despite a rather abrupt ending in August.  The Pennsylvania QSO Party was a blast as usual and I finally made a sweep of all 67 counties which was a new accomplishment.  I participated in the best Field Day I’ve been involved in for several years and was pleased to operate with some folks I hadn’t seen for awhile.  So perhaps while there may have been less quantity, 2010 was likely the year of higher quality.

Looking forward I’ve decided that a new activity and focus in 2011 is going to be activating summits in the Summits On the Air (SOTA) program.  Most areas of the world have SOTA associations that designate the official summits with an identification number.  You can both collect and activate summits and receive awards for both.  My interest is mainly in activating summits.  

SOTA appeals to me for several reasons.  I’ve always been interested in operating in remote and often desolate locations.  There’s some satisfaction in being far away from civilization and establishing communications with a minimal amount of equipment.  I love to combine hiking and amateur radio.  Operating from the trail gives me yet another reason to hike and gives me goals to pursue.

I’ve also had a desire for some time to go on a DXpedition, like somewhere around Antarctica.  I have just about all of the James Brooks 9V1YC DXpedition videos which have stirred up my desire for adventure.  Unfortunately I don’t have six or eight weeks for a vacation at this point in my life nor I do I have the requisite $30K to $40K needed for a trip like this.  But I can dream.  While SOTA summits aren’t like Heard Island or Bouvet, I can make my own little DXpedition adventure.

I haven’t activated a summit yet, but I’ve heard that activations can amass sizable pileups as many people are hunting for SOTA summits, especially in Europe where the program originated and it appears to be quite popular and growing.  It seems SOTA is just getting geared up here in the States, with four callsign area associations established just this past year and two others established in 2009.
