Rainy season in Costa Rica

Unfortunately, Mother Nature has not been cooperating. I’m writing this from Costa Rica and we’ve have a lot of rain here. I was able to get on the air very briefly after arriving on Sunday, making a single contact on 20m mostly just to make sure that the gear was working. I got a little bit of RF into the radio (which I’d seen while testing at home) but the ferrites that I’d brought cleared that up.

The next time I was about to get on the air was Tuesday afternoon, also relatively briefly. I set up for 15m and the antenna behaved very well there, easily tuning the whole band. I worked a few stations in the US southeast (Georgia & Florida) and a relative local in Venezuala. But as the title of this post indicates, rainy season has started here and it’s been raining a lot since then.

Obviously a Buddipole will work in the rain, but the way things are set up here it’s not practical to leave the antenna up and run out in a near-monsoon to make an adjustment to a whip. Of course, trying to do that when there’s lightning around, which there has been, was an even worse idea.

Wednesday was pretty much a complete rainout, though my friends and I were able to go out on the water and jet ski for a couple of hours. (No, I did not attempt to operation TI7/K2DBK/MM). Did I mention that it rained constantly during that whole time?

Today (Thursday) started off looking bad again, raining for most of the early morning, but it did clear up for the majority of our day which included a sightseeing tour to the Rincon de la Vieja volcano. Right at the end of that trip it starting pouring yet again, and while there was a very brief respite after we got back to our residence here, it’s been raining steadily ever since along with a lot of lightning. Needless to say, no radio.

The weather forecast for the next couple of days calls for more of the same, although our touring plans are done and since we’ll be around more I hope that if we get a break from the rain for a few hours I’ll be able to get on the air.

I am disappointed that I haven’t been able to get on the air more, but I’m trying to stay positive and see if I can get on the air for at least a few more hours before it’s time for us to leave.

Quick update on TI7/K2DBK

I just wanted to post a very quick update regarding my TI7/K2DBK operation that’s coming up in a few days. I see that my announcement to the various DX Publicity sources that I’ve collected has done the job, as I’ve been mentioned in most of the major DX announcement lists. As mentioned, this is a “holiday-style” operation which means that operating will take place when I’m at the QTH where I’m staying (as opposed to sightseeing, etc.)  and not otherwise occupied with other important things, like working on my suntan, swimming, or consuming the occasional “adult beverage”. (Come to think of it, I could do at least some of those while operating, but I think I’ll skip trying to operate from the swimming pool.)

Although I wasn’t home to take advantage, I noted that 6m was open today and if that happens again while I’m there, I’ll try to get on the air on that band. However, unless there’s some indication of a band opening I probably won’t spend much time just CQing since the lower bands should be more productive overall.

I had intended to post several updates this week, but as luck would have it this was an extremely busy week at work and I got home significantly later than usual and just haven’t had the time to update. I may post a few updates from Costa Rica when I’m there at which point I may have a better idea of when I’ll actually be on the air.

Until then, I’ve got to get back to packing.

Planning for Costa Rica

The possible operation to Costa Rica that I mentioned a few weeks ago is now on. I’ll be operating from the north-west part of the country near the city of Liberia from the 10th to the 17th of July 2011. You can see the approximate location in this map although the aerial photos were taken before the house were built. (No, we’re not sleeping on a golf course.) We’re going as guests of our good friends Barry and Stephanie who took us along to Grand Cayman in 2007 when I operated as ZF2DK.  (For those of you who haven’t been reading this blog that long, that link goes to a whole pile of blog posts about my trip there.) This time, I’ll be operating as TI7/K2DBK, with the TI7 indicating that I’ll be operating from the Guanacaste region of Costa Rica.

As I mentioned previously, the location is wonderful, overlooking the water from a house that’s basically built onto the side of a cliff. The location where I plan to mount the antenna is a 2nd story balcony (which is actually more like 3 stories high) and the ground falls away very rapidly so the antenna height will effectively be more than high enough to get into the free-space radiation zone. (I hope.)

Although I initially planned to bring my Buddistick antenna, which is a muti-band vertical, I decided to upgrade to it’s “big brother” the Buddipole, which is a multi-band dipole that’s easier to tune and has some directivity and more gain. (I actually decided to go with the mini-Buddipole, which is the same size antenna but breaks down smaller for traveling.) I also picked up an 8′ shock-corded mast which collapses down to just 11″. I’ll secure that to the balcony railing with some bungee cords and I’ll be all set.

I did a little testing of the antenna this past Sunday during Field Day and made contacts on 10m, 15m, and 20m just to do a “smoke test” of the setup. Unfortunately, at the time I started testing the band conditions weren’t very good for DX so all my contacts were domestic, but I had no trouble working a few west coast stations. I think that with the added height plus the fact that I’ll be DX I should do just fine from Costa Rica. What’s that expression? Being DX adds how many dB to your signal strength? (For anyone who doesn’t get that joke, drop me a note and I’ll explain.)

I haven’t had as much time to prepare for this trip as I did for my trip to Cayman, but fortunately since then I’ve made a few more trips to Florida and pretty much have the gear situation down, though obviously I can’t run to Radio Shack if I discover that I’ve forgotten an adapter when I’m in Costa Rica. I did send out a note to some of the DX publicity contacts that I collected when I went to Cayman and I’ve started to see my operation show up in a few of the DX bulletins. The next thing I’ll be doing is to start going through the checklist I developed previously to make sure that I have all the equipment that I need before the trip. I’ll be doing that during this week and will probably do a bit more antenna testing over the upcoming July 4 holiday weekend.

One other thing that I did over the weekend was to test the software that I found for the iPad to see how suitable it was for use. I found a program called HamLog and while it’s not nearly as full featured as my regular DX logger (DX4Win) I think it will work out well enough. There were a couple of issues when logging Field Day contacts, since it’s not really set up too well when there is a piece of info (other than time, date, and callsign) that changes each contact, but as DX I expect (or at least hope) that I’ll be able to just sit on a single frequency and only have to change the callsign for each contact I log. (The program logs the time of each QSO and can be set up so that all other fields, such as the frequency, signal report, and mode stay the same for each QSO). I’m pretty confident that this will work, but I know that I can always fall back to paper logging if necessary.

I’ll be posting more updates over the coming days, stay tuned.

Now that’s service

Saturday afternoon I was going through my QSO logs in preparation for a long-overdue bureau mailing. One of the things I do prior to doing a mailing is that I validate that I still need the card (sometimes I’ll get a confirmation for that band/mode from another operator, or sometimes it’ll get confirmed via Logbook of The World [LoTW] since I initially flagged it) and I also check to make sure that I’m not sending to a bureau that doesn’t exist, or sending via the bureau when I could send direct to a US manager.

In going through the log, I discovered that I had an unconfirmed QSO with Joel, V44KAI on 6m from 2009. That was my only contact with V4 on 6m so I definitely wanted to confirm it. I noticed that I had two other contacts with him (on different bands) which had been confirmed via LoTW, but not the 6m contact. Joel’s qrz.com page explain that because he sometimes encounters QRM/QRN that it’s a good idea to contact him before asking his manager, W5TFW. I emailed Joel who replied that some of his older logs were on paper and hadn’t been put into electronic form so that they could be uploaded to LoTW.

On Sunday morning I got another email from Joel who told me that he found the (valid) QSO in his logs and had emailed his manager to give him the details so that it could be uploaded to LoTW. I checked and probably within 10 minutes of my seeing that email I found that the matching QSL record was in the LoTW system, confirming V4 on 6m for me.

The reason that I wrote this is because to me this exemplifies the ham radio spirit. Joel is clearly an active ham (try a search for V44KAI on the DX-Summit search page and you’ll see what I mean) and as Joel says on his qrz.com page, his manager obviously keeps busy keeping the records up to date. The fact that both of these guys took the time to quickly respond to my question and do the work necessary to provide me with the confirmation I needed helps remind me that despite some of the less-altruistic hams floating around, there are still plenty of good guys. Thanks to both of them for that reminder.

Edit: I was asked what a “manager” is, so by way of explanation:
A manager is a person who handles someone else’s QSLing duties for them. There are all kinds of reasons to have managers, including having the manager in a country with a better mail system to reduce mail theft, or simple because the DX station handles a large volume of cards and can’t keep up with it themselves.  

Monitoring Solar Cycle 24

Now that solar cycle 24 is definitely underway, it’s good to be able to monitor what the sun is doing since as hams, it dramatically affects our ability to communicate. I’ve used dx.qsl.net/propagation/ for a long time as a site that I can go to for a quick overview of what’s going on, but for more in-depth information I’ll stop by solarham.com (aka http://solarcycle24.com). Kevin, VE3EN put this site together in 2006 to track the status of the then-upcoming solar cycle 24, and he’s kept improving it since then. On that site, there’s information about the current solar conditions (flux, sunspots, flares, etc.), historical data (such as the chart I’ve included in this post), solar images, and a message board where there are some fascinating discussions, many by recognized experts in their field. Kevin’s even built a version of his site that’s perfect for viewing on mobile devices, so you can view it while on the go.

Kevin’s been funding this site primarily on his own since it’s inception, although he does have a way to make a donation if you so choose. He’s been very low-key about this, but on a recent visit, I saw that he’s got an impossible-to-miss banner up on his website asking for help. Apparently his full-time job has been “off-shored” and he’s not sure that he’ll be able to keep the site available. If you click on that link it will explain the situation more fully. I have no interest in this site other than as a visitor, but if you find it useful, you might want to consider making a donation to help keep the site (and Kevin) going.

More silly things heard on the radio

This is a follow-on post to my recent post “Weird things heard on the radio“. If this keeps up, perhaps I’ll make this a series, though I’m not sure that “weird” is quite the right word. Silly is more like it, and I’ve adjusted the title of this post accordingly.

As I write this at about 18:30 GMT on 23 April,  I am attempting to work 9M2TO from West Malasia on 17m phone. He’s got a good-sized pileup and of course, there’s the usual guys who can’t figure out how to turn their VFO to tune up their amplifier off the frequency. For non-hams who might be reading, this sounds like a high-pitched squeal on the frequency, and is pretty annoying. Aside from it being rude, it’s in violation of FCC rules against intentionally interfering with ongoing transmissions. (I’m sure that it’s against the rules for amateur radio operators in any country, of course.) That’s not the silly part, that’s the annoying part.

Here’s the silly part: As usual, the DX Cops are present, and one of them said the following: “Hey, don’t tune up on the frequency”. Some of you will immediately know why this is silly, but I’ll elaborate: Under normal circumstances, when you are transmitting you are not receiving. Aside from the fact that the guy who was tuning up likely doesn’t care what anyone else thinks, he’s not going to hear the guy yelling at him. All it does to yell is to add to the noise, which is as bad as the guy tuning up.
