Bursting with Options Elecraft K2-100 plus ATU Up for Auction

I'm making room in the shack and collecting cash by selling one of my two K2s on eBay. I'm the second owner for this unit, which was professionally built and has, I think, every option possible from Elecraft including the KSB2, KNB2, KIO2, KDSP2, K160RX and K60XV.



For the record the serial no. is 02445 and the firmware is rev 2.04P/1.09. It has the AF pot mod also. The rubber band thingee on the tuning knob was there when I got the rig. It's easy to remove if you don't like it.

My XYL is carrying the radio on her trip to Chicago next week and will ship the radio to the winning bidder from there. Shipping will be free in the U.S. If you are outside the U.S. and win the rig, email me directly for arrangements to ship it to you. I'll deduct $30 from the actual shipping costs for non-U.S. shipment.



Costa Rica Call Sign Prefixes and Foreign Operating Requirements

Costa Rica's Call Sign Prefixes

Every once in a while, a radio amateur contacts me about the rules for foreign operators, which leads to the question of which call sign prefix they should use for their final destination. I don't have them memorized, they are hard to find on the Internets and I can never find a file showing them on whatever computer I'm using. So long as I can remember that I put it here, I can access it quickly and send the link to others.

The new SUTEL radio regulations that I wrote about previously are continuing to be fleshed out. They are silent about the use of TI0 or TI1, but I assume those are reserved for clubs or special events. The latest link to Costa Rica's Amateur and CB radio regulations is here.

As of late 2014, SUTEL now has a more organized web page for Costa Rica and foreign hams.

Cocos Island - Rare DX and Great Scuba Diving

TI9 is Cocos Island, which is uninhabited except for park rangers. By the way, why such a small country needs all these different prefixes is beyond me.

 It's a dream of mine to operate from Cocos Island someday. My pile-up skills may never be adequate for manning a station at that rare DX however. I can imagine the grumbling by DX spotters already, hihi.

Additionally, it's a logistical difficulty to operate from there because visitors are not allowed to stay overnight and it's a 340 mile boat trip from Costa Rica's Pacific shore. Perhaps one could operate from a boat anchored off the island. Even if I could not manage to operate from there, the diving is supposed to be superb. Cocos Island makes worldwide top ten lists regularly for the best scuba diving destinations.

Selling a Slice of Paradise Pie in Costa Rica

Though our son's college days are still at least a couple of years away, my XYL and I decided it's a good time to add to the lad's college fund and free up some more time for other projects, so we are dividing our farm and selling pieces or the whole shebang if someone comes up with our price. We wouldn't be leaving Costa Rica in any case, however.

There's no need for me to go into the gory details here as it's all laid out on my other blog, in this post about our sale and on this fixed page that gives more details about each lot.

Special deal for hams who want to buy the house: I'll throw in my rigs and antennas at no extra charge! That would be a couple of full K2s, Ten Tec Argo V, 500W amp, lots of tuners, etc. and five antennas already up.

Can You Help Us Ship PCs to Poor Costa Rican Families?

Update: Ulis, K3LU, put us over the top on this fundraiser! Thank so much Ulis!! The campaign still has 7 days to run, so if you want to add to the pot, it would be very much appreciated. 73!

No, this is not a strictly ham radio related post, but it is kinda electronically geeky, so close enough I hope.

When we moved down to Costa Rica in late 2008, I carted down a lot of older PCs and spare parts. That was partly because some of those already worked and we'd need them and partly because I like tinkering with the old machines (well, PIIs to P4s, not 8086 boxes) and saving what most people would discard.

That side hobby morphed into a very modest program of finding or receiving donations of old PCs here, getting them to work, loading them with Lubuntu and donating them to some of the poorest, local neighbors who otherwise would not have a computer in the home. There are plenty of folks here that get by week to week and have no way to access the Internet and need the help of a PC to keep up with the other kids in school.

Kapipal PC shipping campaign poster
We need $300, minimum contribution is $1
Very recently, I decided to ask for help from my Facebook community to raise funds to defray my out-of-pocket expenses for the many spare parts I need to complete some systems, such as memory, drives, power supplies, etc. That was a roaring success. I raised the $250 I hope for in less than a week.

During that campaign, a fellow who lives in Florida told me he had 20 Core2Duo Dell desktops in working order that he had wanted to ship to Guatemala. He found the red tape too much to overcome, however, so he offered them to me if I'd pay for the shipping to Costa Rica.

I immediately contacted a shipper I know well and he agreed to waive his agency fee and give me the highest volume (lowest rate) price for this modest load. All together it comes to just $15 per PC or $300 total.

Thus, without giving folks a breather from the last campaign, I am again asking (on Kapipal) for donations to offset the shipping costs. I'll be giving the machines a thorough checkout, loading them with Lubuntu and plenty of apps and finding them homes. I qualify the recipients through trusted Tico friends, so I know they are going to families who will use them and I'll be inquiring about the need for these at local schools and libraries as well.

Long story short, can you help? Even a $1 donation helps, believe me.

Here is the link to the Kapipal campaign: http://www.kapipal.com/5d29e5ebabec4c8db18db0ffa7c1c449

I would very much appreciate it if you could share this news with your own networks.

Tnx es Vy 73!  - Casey

P.S. For a $15 or higher contribution, I'll stamp your call sign into the case of one of the new machines, hihi! :)

6 Meter Homebrew Yagi Tunes Up! Hooray!

6-meter yagi from below on mast
The 6-meter Yagi at full height
With the impetus of several suggestions from the QRZ Forums Antennas group, I made a great leap forward in tuning up the homebrew 6-meter Yagi. First things first, I replaced the test cable to the AA-54, which had an intermittent short or open in one connector. I made a longer cable so that I could step out of the antenna's immediate shadow and used bigger ferrites for the choke on the cable. While I was waiting for the PL-259 to cool down, I made a quickie 5 turns coax choke on a 3" form too.

I discarded the few turns through a 2" ferrite choke on the antenna feed line and inserted the 3" choke. Already the disparity between the SWR R/X readings on each end of the feed line was vastly reduced. I went back to adjusting the gamma match again and when I had it to an acceptable range, I decided to pull up the antenna mast to full height, which I can do single-handedly thanks to my counterweights at the bottom of the mast.

Need Help Tuning 6 Meter Yagi

I'm trying to dip my toes into VHF-land starting with six meters. I've built a 3-element Yagi, plumber's delight style with a gamma match and it's now sitting on the mast at about 6 feet off the ground.

The half-inch aluminum elements were cut to a calculated length for 50.124 MHz and it's not far off in the test position. Trouble is, though I can tune it fine at the antenna, at the other end of about 100 feet of RG-8 PE core coax, the readings are way off, though there is a distinctive dip (actually two).

Hand Delivered QSL Cards from UX5UO and A New Straight Key from Ukraine

Last year, my elmer and good friend, Dan Keefe W6WU (ex-KS6Z, K6FFF), became a silent key. I very much miss our regular email exchanges that included his stories about his family (one of whom was U.S. Labor Sec'y, his political activities, and his own tales of being a Marine Sgt. who served in Korea at the Battle of Chosin Reservoir. He was a remarkable self-made millionaire several times over who also personally brought food to the homeless and ran his own Veterans rehab program from his home, teaching them carprentry skills even while his health was failing.

He was also my QSL manager. As I have not been active lately, however, that hasn't been much of a problem. I figured I better get some new cards, though, since it would be difficult to retrieve the set Dan had been keeping.

One Ham's Experience Obtaining A Reciprocal Permit in Costa Rica

A little over a year ago, the new primary Costa Rica government agency in charge of telecommunications regulation, SUTEL, came out with regulations of a sort for Costa Rican hams and foreigners wishing to operate from TI-Land. I gave an overview of those new ham regulations plus links to the manual (in Spanish) and the required forms to fill out (also in Spanish) in a previous posting.


Costa Rica SUTEL hands controlling marionette stringsThe first of several hams to contact me for assistance in obtaining a permit was Brian, VE3BWP. Besides trying to understand who to contact and how to fill out the forms (Brian doesn't speak Spanish), the main problem was that the regs say you must appear in person in San José and Brian's itinerary put them nowhere near the capital.


Remarkably, they accomodated his situation such that his operating permit was waiting for him at his hotel in Guanacaste! Below I've summarized the process that Brian went through and include email addresses of key contacts so perhaps the next ham wanting to obtain a permit will have an easier time of it.
