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.

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.

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.

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.

I've spent a couple of hours this weekend (so far mainly on Saturday), playing in the SKCC Sprintathon CW contest ... the rules demand that only hand keys, including bugs, be used. I hauled out my original gray Vibroplex, purchased back in 1964, when I decided that using a straight key was just too slow. I was doing a lot of DXing and contesting back then, with my trusty DX-20, VF-1 VFO and assorted groundplanes on top of my parents three-story house in the middle of Vancouver ... it's hard to believe that it was quiet enough there but those were the days before computers, switching power supplies and and so many other noise-making devices that we have today. They truly were the 'good old (quiet) days' of radio. My favorite contests back then were the 'W-VE', where any 'VE' became instant DX and the subject of good-sized pileups and the CW 'Sweepstakes' ... back when the exchange was, if I recall correctly, just NR, RST and QTH.

My antenna farm sat on our high, peaked roof and consisted of groundplanes for 40m, 20m and 15m ... these were made of inexpensive galvanized drain pipe, about three or four inches in diameter. The 40m one was guyed and also had one end of my 80m dipole attached to it, which ran out across the yard and across the back lane, terminating on one of BC Hydro's wooden (telephone) poles. Every once in a while the telephone guys would take it off and toss it over the fence whereupon I would get out the ladder and re-attach it, where it would stay for another year or so.

For this weekend's CW party, I have put my 'Tri-Tet-Ten' on 20m, doubling from a 40m crystal to 14051.5, placing me pretty close to the Sprint's watering-hole QRG of 14050. I have had way too much fun with this simple one-tube radio since building it, mainly for 10m CW, in anticipation of the present solar cycle's peak years. Although it puts out almost 5W when quadrupling to 10m, I can get a whopping 13W from it on 20m, which is plenty of power to have some fun.

So far I've worked about 40 stations, all on CQ's, since I can't really QSY to answer others ... so if you are around this afternoon, please give me a call should you hear my little rig. It's a real nice change to hear non-machine sent CW for a change and fists ranging from one end of the scale to the other ... really a nice reminder of what the bands used to sound like when I first got on the air.
