So far, the only show I've been able to attend this year was San Antonio. Summerfest isn't looking too probable, and Belton in October is doubtful. Family commitments and discretionary funds because of the economy have certainly limited leisure activities. I got the opportunity to work with an FT-897 and have developed a much improved cabling solution for Yaesu transceivers as a result. The power for the internal audio buffer is drawn from the isolated interface power, maintaining complete isolation between the transceiver and the computer. The cables are now separate, instead of requiring a jumper between the two transceiver connectors. An updated IsoCat and cable schematic are available. See the Alternate buffer power article for more information. |

First show if the year was San Antonio. We had a good time, saw some old friends, and sold a few items. A very welcome break from the holiday season. I'll be at the Greater Houston Hamfest at the Ft. Bend County Fairgrounds in March. I'll have at least one IsoCat, as well as charger kits. |

Summerfest in Austin was a very good show this year. I sold several of the IsoCat kits, and handed out quite a few cards to interested folks. So far, no inquiries but I'm hoping to hear from some of those that took information home. No more scheduled hamfests this month, but I may make Belton in the fall if time permits. Had a major computer crash on the laptop and am just getting that back up to speed. I also got Ubuntu loaded on the big desktop (finally) with dual monitors working. Took a bit of creative editing of some of the files, but both Linux and XP are on the same machine with all features working in both. Based on what I learned with that effort, the laptop is next! I'll may be in Brenham in October, and we may go to Corpus this fall. Ham-A-Rama is probably not gonna happen this year, though. Maybe next year. By then, I should be flying again and that would make it a much more practical trip. With all that has been going on this summer, work on the latest project has been slower than I wanted it to be. We're taking a short vacation later this year, so maybe I'll be able to finish up the last few bits and get it ready to go to the board shop when I get back. What is it, you ask. Check back - it is mostly surface mount, is based on previous projects, and will probably be offered as a completed unit. Oh, yea - if you have Icom or Yaesu radios, you probably need one! |

I didn't get to go to any of the shows last fall, and missed Belton due to family commitments. Not looking so good for HamCom either. Probably the next show will be Summerfest in August. This depends on whether our newest grandchild sticks to his/her arrival prediction. I have been busy trying to work the kinks out of a way to produce completed IsoCats for sale, but not having a lot of success in keeping it economical and efficient. I am nearing completion on several units for the next show, however. I also have a new product in the wings and hope to have it ready for sale by the next show. This one won't be a kit, however, as it is all surface mount. I'll build the first batch myself. After that, I am looking at turnkey production houses to get reasonable quantity and keep costs down. More on this exciting new accessory later. I have also updated the website to make it easier to manage and to prepare it for growth. As I add projects, the website needs to grow with them. I am also considering setting up an interactive area where builders can exchange ideas and submit questions. |

The Texas City Hamfest was rewarding, though not too profitable. I spent more than I took in, but picked up a few items I needed. I bought a roll of RG-58 to build some antennas with, as well as an antenna tuner to go with the IC-7000 in the mobile. Still looking for the perfect mobile antenna... I used the free time this month to put up a few more IsoCat kits, as well as build one for sale. I'm planning on having a few built by the end of summer. Check back, I'll announce availability as soon as I get them built and tested. I worked up a schematic to use the IsoCat with Yaesu (-817, -857, -897) transceivers. It is posted on the website, but as I don't have a Yaesu to test with, it is 'beta test' until I get confirmation that it works as planned. A new project is on the drawing board. I should have prototypes running by the end of September and if all goes well, product should be available for shipment by mid-November. We're heading to Austin on August 3 and 4. Hope to see you there. |
