Perseids Peaking

It's been a few years since I have been active on 2m meteor scatter during the Perseids meteor shower. The year's largest shower peaks tomorrow night, although the peak is sufficiently broad to provide activity over several days leading up to and after the night of August 12/13.

Nowadays, using FSK441 WSJT software, a lot of good fun can be had most non-shower mornings on meteor scatter, just using random meteors. My experience when using the same software during an actual shower has been disappointing, as often the signals are too strong or too long for the software which is looking for shorter, weaker signals. During a large shower such as the Perseids, where typical burns can be quite lengthy, my own experience has given better results with good old SSB or fast CW.

I clearly recall my first-ever meteor scatter QSO, made during the May Aquarids,  back in the early 70's. I had arranged a sked with Ken, W7JRG, in Montana. I had grown up reading about Ken's VHF exploits in both QST and CQ as a teenager and was excited about the possibility of finally possibly working him. My station was homebuilt, using a 6360 transverter driven from my Heath HW-100, and feeding a homebrew 5894 amplifier with 1/4" copper tube plate lines. The amplifier produced just a shade over 100W output. My antenna, also homebrew, was a 24-foot 13 element Yagi ... probably not the best for meteor scatter although it worked well enough for me to ragchew every night with stations in Portland, Oregon on SSB.

A few minutes before our sked, I decided to make one final check of my system. Our sked was to be on SSB, using 15 second sequences. I keyed down at full-power and did a final tweaking of plate tuning and antenna loading, and unkeyed, back to receive mode after about 30 seconds of tuning up. My receiver immediately sprung to life with a very loud SSB signal, slightly off-tune. Thinking it was my local buddy, VE7BLF, calling me before the sked, I was surprised to hear a different voice ... it was Ken in Montana at S9++ ..."I've been holding my breath waiting for you to unkey there Steve ... thought you would never finish!"



Needless to say I was just as surprised as he was. We talked back and forth for about another 60 seconds before the burn finally dissipated and signals were gone. What a great introduction to meteor scatter, with the QSO completed before the sked even started! Ken later told me that of all of the meteor contacts he had made, it was one of his best ... I guess we just hit it right.

Of all the showers, I always found that the December Geminids was the best, even better than the August Perseids, at least for the North-South path. Having said that, my longest meteor contact was made during the Perseids, with Arliss W7XU in South Dakota ... just a shade over 1300 miles while running just 40W SSB to a 9el Yagi.




Good luck if you are doing some meteor scatter tomorrow or even if you are just watching the shower visually ... conditions should be ideal, if the skies are clear, as the very new moon's sliver does not rise until near dawn.

How I Worked VY0M From a Tent

In my last post I described my QSO with VK2SSI while experimenting with portable antennas in my backyard. Well the reason I was testing portable configurations is because I needed work Cezar, VY0M, from Melville Island, IOTA NA-248, located in the Canadian arctic.  I knew that the scheduled expedition would occur during the week that I was at Philmont Scout Ranch in Cimarron, NM attending a training class and I would be sleeping in a tent for the week. New IOTA's are getting rare for me, with 1,050+ confirmed so I didn't want to miss this one.

I experimented with multiple antennas as I didn't know what I would be allowed to do at the camp. Would I be allowed to put up an antenna in camp? Would I have to find a remote location somewhere else? How long would my batteries last? So my plan was to try a Buddipole vertical first. It was relatively low profile and wouldn't attract a lot of attention. So I set up the station, in my tent, for a dry run.

As luck would have it, there was a 110v plug in my tent, the power intended to power a light and possibly a fan, so exit the batteries and in with the power supply. I set up the vertical and the antenna worked fine. I was using a Yaesu FT-857, which is a very capable radio, especially for portable use.  With 70 watts I worked into Europe with good reports, so I was thinking that I might just get by with this set-up. However, the first day that VY0M came up, he was on SSB. I never heard a peep from him and decided it was time for plan B.

After erecting the vertical, a few around camp inquired about it and everyone thought the radio set-up was cool, so the next afternoon I decided to put up the bright orange Jacktite, 30 ft.  collapsible pole with an end-fed long wire through a 9 to 1 balun. After I got everything connected, I turned on the radio and tuned the antenna with an LDG tuner. Everything looked good, so I checked the spots on my iPhone and Cezar had just moved to CW. I went to 14.040 and there he was with the fluttery signal common to stations in the far northern latitudes. After two or three calls I had him in the log, Victory dance. All the planning had paid off and I had another IOTA in the log.

What a blast ham radio is. Below is video of the set-up, right after I made the QSO. I didn't have the narrow CW filter on the FT-857, so the stations you hear are actually 1 KC up, but you can still hear Cezar's fluttery signal if you listen closely.

Coax losses

If you are like me, then you always want to know the loss of your coax at 6m,2m and 70cm, possibly higher I found this very useful table to compare various coax cables at different frequencies. You may have your own favorite table! If not, I hope you find this one useful.

See http://www.w4rp.com/ref/coax.html .

Yaesu FT991

As I have said several times before, there is only one commercial rig that I fancy currently and that is the Yaesu FT991 that covers all of HF plus 6m, 2m and 70cm. However the UK price is still too high so I can wait and wait until the price drops. At £999 it will get serious consideration, but not at any higher price. The only other rig I fancy is an FT817 replacement, which may come later this year. Most of my operating is QRP and a 5-10W rig would suit my needs well.

2m big wheel

Well, I have ordered one (yes I know I could have made one although not in my present state) so I hope this can be erected in the next few weeks, although I shall need help to do this as I am no good on ladders in my current poor state of health. It would be good if I could get a long wire erected at the same time for LF/MF use, although this could wait. At this time I am going for a single big-wheel rather than a stack.

I have decided against buying a 70cm big wheel at the same time as this would require a new length of low loss cable too. I also checked my existing low loss cable and this seems in good condition, so it will be reused. I may make my combined 2m/70cm antenna into a portable antenna when I have found out why the VSWR is poor.
