For anyone thinking of purchase, be sure to check with your credit card about fees. Mine charged a flat $2 transaction (money exchange) fee. Others may charge more.

He said the Swan's drift was about 3 Hz. Given what similar huff-puff kits cost, they appear to be an excellent value if you have need for one of them. At today's exchange rate, the cost for an X-Lock kit is $31.26.

With input from Joe KC9LAD on the "watch outs" and rit interface resistor network, I built and installed my x-lock in one day. I did make a minor change of putting the headers for the plugs in sideways. Mounting on the bottom of the main TR7 board, that allowed me to keep the device plugs so that I can unplug if needed. This is a good kit, but not a Heathkit, so have at least some electronic knowledge before you start. Since I get only limited on the air time, I can only say that to date, I absolutely love the thing. As net control, I no long bump the dial as my TR7 coasts around. The price with British pounds to dollar conversion, shipping etc is about $40. Just my $.02 73, Ron WD8SBB --- On Fri, 2/11/11, Joe Pyles <[email protected]> wrote: From: Joe Pyles <[email protected]> Subject: Re: [Drakelist] The X-Lock for the TR-7 To: "Drakelist" <[email protected]> Date: Friday, February 11, 2011, 9:43 AM I bought an RV75 several years ago to stop drifting. It works very well. But I installed Conny's DAFC in both of my TR7As and seldom use the RV75 any more. I use it for split but thats about it. With the DAFC I can turn on the TR7A and immediately begin using it with no drift . The modification is completely reversible so if you want to make the radio back to original no one would ever know it's been there. By the way the installation is far from "open heart surgery" you don't even have remove the top cover just the bottom plate, solder 4 wires and 2 coax cables and your done. You don't have align anything just put the bottom cover back on and use the radio the same as always except no drift. 73 Joe KC9LAD Tom, I did a bit of research on huff-puff stabilizers a month or so back and the one that seems to be preferred for the TR7 is DL1SDQ's "Digital Automatic Frequency Control." It's about $114. Info on it can be found at http://www.conny-dl1sdq.de Incidentally, after a good bit of research on the subject, I decided to not make any changes to my TR7. It is what it is and I thought I'd leave it that way. The best stability solution without doing open heart surgery on it is probably to get an RV-75 although they're a bit scarce and when you do find one, it's likely be a bit on the pricey side. 73, Tony K4KYO -----Inline Attachment Follows----- _______________________________________________ Drakelist mailing list [email protected] http://mailman.zerobeat.net/mailman/listinfo/drakelist _______________________________________________ Drakelist mailing list [email protected] http://mailman.zerobeat.net/mailman/listinfo/drakelist -----Inline Attachment Follows----- _______________________________________________ Drakelist mailing list [email protected] http://mailman.zerobeat.net/mailman/listinfo/drakelist
