In response to Mike Sattler's and Gary Coffman's comments concerning military radios and their whip antennas, let me clarify a few points from an Army perspective. 2. Our major family of radios for our tactical units operates in the 30.0 to 75.95 MHZ range, in the FM mode, and in two power ranges: high @ 35 watts; and low @ 4 watts. 3. From a tank (either Abrams or the older M60 series) I can usually talk reliably 20 to 30 miles on high power on "good" (relatively flat) terrain. Low power is usually good for about 5 miles. In the hilly terrain of the Fulda Gap in Germany, these ranges are reduced significantly, but usually suffice for normal tactical unit communication needs. 4. Hope this helps. 73, Colonel Richard Knox KD4BRL knoxr%ccmail@tacom-emh1.army.mil ------------------------------ Date: 2 Nov 93 08:14:33 EST From: psinntp!arrl.org@uunet.uu.net Subject: Mobile Transceiver Installation Guide?

Paul, We have installation guidelines for several manufacturers (GM, Toyota, Nissan, Volkswagen, Mercedes), but nothing for Ford. John Ochs, Ford Public Affairs, 3000 Schaeffer Rd, Dearborn, MI 48121, told us in a letter that dealers have access to "Technical Service Bulletins" that should help, although he did not tell us what they were or what is in them. All in all, Ford had a fairly good response to our inquiries, but, like ALL of the manufacturers, they said that if any aftermarket component causes damage to their car, it will not be covered under warrantee. I am compiling files by manufacturer, so I will send the Ford file to your address in our membership records. I will also include the best of the installation guidelines -- GM's. Our book, Radio Frequency Interference -- How to Find It and Fix It, also has a reprint of the GM guidelines in the automotive EMI chapter. (Anyone wanting a copy of the GM installation guidelines and one of the auto files, please send me a large -- 9X12 -- SASE with 98 cents postage -- I will send it right out.) And, as always, I am looking for any and all reports on problems or solutions to auto (or any type) of EMI problem. 73 from ARRL HQ, Ed >I looked at the ARRL "auto-list" and called the number listed for >Ford.

If you are using an ARE ARE-60, chances are you have an old version of the firmware. The latest version is Ver. 4.0 - (2 EPROMS) Call AEA (Hadley Allhands) for more info on how to obtain the new firmware. 2. Change R14 from 130K to 248K if you have Touch Tone falsing problems. The tone detection was much too fast and would cause HamLink to false. In the middle of a QSO, often the radio would QSY some where else. The 248K resistor solved this problem. Hamlink still decodes tone very fast (setting #6 or slower on the Alinco DJ-580) Careful when changing this resistor as the foil near the 8870 IC comes up from the board very easily. 3. Older units used a 13K resistor at R10 to determine confirmation beep level. It was much too loud so they put in a 100K resistor in all their newer units. This was still too loud for me so I replaced it with a 1M 10 turn pot. This allows me to adjust the level to my taste. 4. If you are using HamLink with a Yaesu FT-1000 or FT-990 you might have problems getting the unit to communicate with the radio. ( Via the CAT port). If this is the case, place a 2.7K resistor between pins 1 and 2 on the CAT DIN connector (serial date + ground). 5. I moved the internal programming jumper to a toggle switch on the back panel. Same for the reset switch. (Drilled 2 holes on back panel). Brought out an extension plug from the internal RJ-11 jack with a double female connector. With this arrangement, I don't have to open the HamLink every time I want to program the unit. 6. Bug that remains; #71# - pin 9 on the D25 connector should go high for 100 mS after the command is received and does not. All other ON-OFF functions work fine. AEA was made aware of the problem in June, perhaps there has been a fix since. 73, Rich WB2JBS ------------------------------------------ Disclaimer: The opinions expressed here are mine and may not reflect the policies or opinions of my employer. ------------------------------ Date: 3 Nov 93 14:20:54 GMT From: ogicse!uwm.edu!linac!att!cbnewsm!hellman@network.ucsd.edu Subject: MorseTrainer for Mac To: info-hams@ucsd.edu I have not been able to run any MorseTrainer pgms.

The Visar is a tiny 5-watt 16-channel handheld, designed for police and similar applications. It is available in VHF, UHF and 800-MHz-trunked models. Cost is $1,095 each. (At least that is what I recall the salesman saying.) The Visar has an LCD channel display mounted on top at a 45-degree angle, so it is visible from above (if the radio is in your shirt pocket) or from the front (if you have it in your hand). Of course, that means that the display must be upside down from one or the other position. The neat feature is an invert button. Press it and the characters in the display electronically invert! No need to read upside-down numbers!

The drive level from the UTU audio output was way too high for a mic level input. I used a resistive divider in the output of the UTU (right in the mic connector shell). I think it was 10K and 600 ohms to ground from the UTU audio output. (10 K on the UTU side, 600 to mic gnd). The mic line to the Yaesu comes off of the tap between the two. Works like a charm. The mic level pot on the rig now sets the proper output level when it's at about 12 o'clock. Looks like this: aud. from utu --------+ | > R1 < 10K < +---------- Mic to rig > R2 < 600 ohms > | sig gnd from utu ------+---------- Sig gnd to rig Oh and yes, FSK is better, if you have it. Adjust the value of R1 so that your transmitter output level and mic gain pot track about the same as it does in SSB. If your using with FM, use a deviation meter. If your interested in the exact values, email me and I'll check out the rig at home tonight.

I was able to send packets to MIR as they were confirmed by a "busy" packet coming back. I have also made one successful connect to MIR on Oct 13. I've tried the shuttle on the STS-58 mission, but had no success with them on voice or packet. I could hear them, but they apparently couldn't hear me. I've heard OSCAR, but don't have a radio capable of transmitting on 435.016 MHz. (Also a 5 KHz freq step on my HT is a little "rough" when compensating for Doppler shift.) So with an HT and a good antenna, MIR is doable, the Shuttle is a little harder, and OSCAR would probably require more hardware/power/antenna. But that's what experimenting is for. 73 Dave N0UVR dfk@col.hp.com ------------------------------ Date: Wed, 3 Nov 1993 07:10:45 GMT From: swrinde!elroy.jpl.nasa.gov!usc!yeshua.marcam.com!zip.eecs.umich.edu!umn.edu!csus.edu!netcom.com!msattler@network.ucsd.edu Subject: We've lost him, Jim!
