It probably is true, but not because of the lead toys. There's a requirement to sell reduced-lead or lead-free electronics into the European Union and other areas of the world, which has been ramping up for years now. Google search for RoHS. You'll find lots of hits on the topic. It took effect in July of 2006 in the UK, the EU, and elsewhere, as specific country's rules have been rolled out. Manufacturers have been redesigning various products for a number of years now, as the deadlines came due. Many of the redesigned radios that you saw from Kenwood, Icom, Yaesu, and everyone else at Dayton (Alinco is BEHIND) weren't JUST to have new features/functionality for hams. Most of them carry an RoHS sticker, and were redesigned boards and components that don't use lead in the soldering process. No they weren't JUST happy to bring us new products, they weren't going to be able to sell ANY products into Europe without RoHS compliance... thus the whirlwind of redesigned and newly-designed radios at Dayton, and the cancellation of some older products forever, like Yaesu dropping the FT-847 which actually filled a market niche pretty nicely still, but probably couldn't be made RoHS compliant. You'll start to see RoHS stickers on just about every electronic device made now, indicating that the product passes the lead-free standards being required by many countries. http://en.wikipedia.org/wiki/Restriction_of_Hazardous_Substances_Directive We'll see if the tin whisker problem that many of us are familiar with in older GE MASTR II receiver castings -- starts to become wide-spread in more typical electronic devices, with the removal of lead from the soldering process. (There's some references to the tin-whisker problem and a photo on that Wikipedia entry above.) Time will tell. Nate WY0X

I bet the Mark III is RoHS-compliant, per my last note. For the other person who mentioned that there's discriminator audio at the DB-9 on the back, they're correct as long as the optional packet TNC inside the rig isn't installed. For a rig without the TNC or with the cable from the DB-9 hooked back up to where it came from instead of the TNC... the pin-out is this, according to the manual: 1. SQC squelch signal output. Carrier in: closed. Open collector output. 2. Packet reception DATA output (9600 bps) output level 500mVrms/10K ohm 3. Packet transmission DATA input (9600 bps) input level 300mV/600 ohm Max input level 600 mV 4. Packet reception DATA output (1200 bps) output level 100mV/600 ohm 5. Ground 6. No connection 7. PTT signal input: Low (GND): TX, Open: RX 8. 5.0 Vdc output: Max current less than 50mA 9. Packet transmission DATA input (1200 bps): input level 100mV/600 ohm So they're talking about pin 2. The references to packet notwithstanding, since these are just the typical audio and logic interfaces seen in other rigs -- they're just touting the packet ability over and over and over ad-nauseam in the manual...

Re: [Repeater-Builder] 220 link radios
Take a look at this link http://members.aol.com/w8ak/maxtrac222.htm I ran into Glenn, W8AK out at Dayton back in May.. He had a couple of these Maxtracs set up as a repeater on 224 mhz and seemed to work real nice.. I have not tried the conversion myself but it looks like it would be a nice way to link on 222 mhz if someone wanted to give it a try.. Glenn said he does not have the time to do the conversions and just wanted to give it a try and post the results on his website.. Hope this helps and Good Luck with your linking..

I do believe that ADI is out of the US market though James _ to amplify on Skipp's statement about ADI radios, I have a 220 repeater in Skipp's vault on Mount Vaca, and I was using an ADI 220 radio to monitor it. It was on constantly for about six months; the display would become unintelligible, and the radio would stop transmitting. I would do a hard reset, and it would start working again; but it would lose all its programming. I finally gave up and purchased a new ALINCO a year ago and have been pleased with the radio, it just keeps percolating along.

RE: [Repeater-Builder] 220 link radios
Jed, I'm using some synthesized Hamtronics TX and RX modules in a 220 repeater, and they seem to be holding up well. If properly encased and shielded, those modules should perform well in link service. your ready-made options are few... 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Jed Barton Sent: Wednesday, September 12, 2007 8:06 PM To: repeater-builder@yahoogroups.com Subject: [Repeater-Builder] 220 link radios Hey guys, Any good radios to use for 220 linking?

RE: [Repeater-Builder] 220 link radios
Jed , I picked up a Midland 13-508 Old Xtal 220 Mobile, also Made is a Cobra 200 and Clegg Models all the Same, Not sure who made for who, I think they were the First radios around yrs back when people started putting Repeaters together , The Xmit Board and Rec Board can be easily separated , I think they would make a Nice link Radio . But Erics info with the Hamtronics would be more up to Date , or the Best thing to do is Just E-Mail Scott Zimmerman - Kevin Custer who run this Wonderful site and have them professional build You one. http://www.repeater-builder.com/custombuilt/index.html Happy Repeater Building Don KA9QJG
