I've owned my TM742A for about a year and a half now, and I've got a really bizarre problem I wondered if anyone might have seen before... About a year ago, I had just finished the installation of the radio in my car, and I started programming the memories with various and sundry frequencies in the Minneapolis area. As I recall, I got into the Minneapolis Police Dept frequencies on 440 (460.100, 460.125, etc), when all of a sudden, the rig completely locked up - wouldn't accept input or anything, and about 30 seconds later, it shut itself down. I sent the radio back to the dealer, and they performed a hardware processor reset - disconnecting the lithium battery, and reconnecting it (the darn thing is *soldered* to the board, of all things...). At the time, I thought it was just a fluke... Two days ago, I was programming the same frequencies into memory, and guess what - it locked *again* - exact same symptoms as before. The processor seems to have locked in some sort of odd loop - if I hold the power button on for about 5-7 seconds, the unit will come on, but all of the display segments are lit up, and it shuts itself down again after a short period of time. It also indicates "-on-" when I turn the ignition on in the car. I plan to give Kenwood a call tomorrow and see if they've seen this before, and if they know of a fix for this problem. Has anyone else seen this behaviour in the 742? Two other minor things I've noticed about the rig: 1. The clock gains about 15 minutes every 6 months or so. 2. Somehow, when I've got the DTMF remote enabled, it'll pick up random noise from somewhere and change some of the settings for the currently selected channel. I know at least one other person who experiences this as well... Any information would be *greatly* appreciated. If anyone knows how to perform a hardware reset without desoldering the battery, I'd be in your debt...

To: ham-equip@ucsd.edu RESPONSE to Jesse Wei's questions: 1. MOUNT. Magnet mounts are fine and, when careful, don't damage paint. You might want to use a piece of waxed paper between the mount and the car body, just in case. The mag mount can easily be removed and put in the trunk. On some magmounts, the cable used is in RG58 which is usually small enough in diameter to go through the large weather stripping of a car trunk without significant pinching. Some mag mounts use a larger RG8 or Japanese equivalent cable which may still go through the weather strip OK. 2. NMO vs. UHF. I don't have the specs but my impression is that there are marginal differences in performance on the 2M or 70 CM bands in comparing the NMO and UHF type connectors for the antenna. If you think you might use 1.2 ghz someday, you may want to consider buying a tri-band antenna with an N connector...BTW, I use NMO and N connectors on my present antennas. The NMO was chosen because that's what Ham Radio Outlet had in stock that day. I.e., I never really had to make the UHF vs. NMO decision but I remember wondering about the differences too on my first antenna buy. Since you'll be using your HT as the mobile rig, you may want to consider putting a BNC connector on the radio end. I suspect this will increase your performance more than the difference between a UHF and an NMO. 3. SPRING/COIL. I'm not sure what you're referring to. I think what you're talking about is that some dual band antennas use coils with Allen set screws and others wind a coil right out of the antenna element, itself. I have no preference and I let the antenna manufacturer/designer decide which is best for them. From my understanding, these coils are integral part of designing a multi-element, co-linear antenna which results in more gain, not losses. 4. ANLI vs. Others. I have not owned the AT-2B model which you've mentioned. My only advice is to take a close look at the antenna's construction and compare it to a top of the line Diamond. I can tell you of my experience with a Comet B20NMO which I owned. The hinge feature was nice but this particular antenna's spring was just weak enough, or the mechanical connection was just off enough causing the antenna's hinge to pop up and lay down when driving on the freeway or going over bumps. Being a good Ham, I tried to take the antenna apart to remedy the problem but broke it and ended up throwing it away... 5. Diamond vs. Comet vs. Larson. I now own a Diamond NR770NMO and it's great and I bought it used too, saving some more money! I also own a Larson 2M monoband which is nice and flexible. I already told you about my Comet experience...oh, and I own a Diamond NR-124 monoband for 1.2 ghz. I think the slightly higher gain, while useful for an HT, would not be as important to me as quality construction. Using an HT, while mobile, I think the gain differences between an SG7500 and an NR770 will be insignificant to you, but do consider the length, too. The SG7900 is 62" and not usually recommended for a magmount. I think an advertised 1db difference may be noticeable but anything less is debateable. 6. LAST THOUGHTS. I trunk mount could also be used which will clamp onto the edge of your trunk. Paint should be OK as the set screws tighten from the underside of the trunk lip and the part of the mount which touches the top of the trunk's paint is also cushioned or designed to protect paint. The cable kits may use the RG58 size or, if using bigger stuff, have a short skinny piece of coax spliced in just for going through tight fitting weather stripping. When parking in questionable college areas I would recommend, simply, unscrewing the antenna from the mount and putting the antenna in the car. Just remember, these comments are just what I would do. Whatever is done is not necessarily right or wrong, and it's all just time and money. If it doesn't work out the first time, just buy (or make) and try again. As often quoted by me, "When in doubt, by both!" Good luck. Your ideas, so far, are sound. I guess you just need to decide on mounts now. -- Lance Lee, KD6DMR Sunnyvale, California USA lance_lee@smtp.esl.com ------------------------------ Date: 28 Jun 1994 01:00:54 GMT From: ihnp4.ucsd.edu!swrinde!howland.reston.ans.net!wupost!crcnis1.unl.edu!unlinfo.unl.edu!gbrown@network.ucsd.edu Subject: Need UNDERGROUND info source To: ham-equip@ucsd.edu Alan - Crawley (amc@cup.portal.com) wrote: : Where can I get underground information fro stuff like: : Modifying a HT to transmit out of band, on any (or alot of) freqs? : Re-programing the electronic serial number of a cellular hand held? : Other interesting projects. : Please email. : Thanks Not here.

I've had an FT-11 for a couple of months and I'm quite pleased with it. I think of all the HTs I've owned over the years, the FT-11 is the neatest, smallest and most fun of all. And yes, it does have wide band receive and AM aircraft coverage. The only thing I miss with this xcvr is a direct dc input jack, but the accessory mobile adapter is reasonably priced and provides dc power for 5 watt operation (you'll really need to buy the external speaker-mike in order to utilize the adapter appropriately.) ------------------------------ Date: 27 Jun 94 13:30:16 GMT From: news-mail-gateway@ucsd.edu Subject: Rechargables in RS CB To: ham-equip@ucsd.edu I guess I was confused about the combination of akalines and dummy batteries and NiCd's.

My Yahoo FT470 & 411 say NO NICADS in the AA pack. My Icom 2SRA (just like your W2A) take NiCads just fine. Its probably because the charger circuitry is built into the Icom radios instead of the pack. Although there may be some danger for some radios, I think the warning is more to protect their battery pack profits than the radio. Brett Miller N7OLQ brett_miller@ccm.hf.intel.com Intel Corp.
