Message-ID: Date: 16 Feb 93 20:01:03 GMT Organization: Rutgers Univ., New Brunswick, N.J. Lines: 28 Here is the mod for the DJ-560. I haven't had my friend try it yet, but thanks anyway to Kevin Jessup for supplying the information!! There is NO mod required to do crossband repeat. It is a standard feature. If crossband repeat operates on the 800 MHz band (after the modification), that is another matter! Performing the aircraft mod (as described in the back of the owners manual, also gets you 800 Mhz). BTW, cutting the RED jumper provides AIRCRAFT and 800 MHz. Cutting the BLUE wire provides out of band transmit (but NO guarantess that performance will be within amateur band specs). To enable 800 MHz, press the UHF key 3 times (to guarantee that your are in UHF VFO mode). Then press the function key (keep it held down) and then press UHF. Have fun! -- Kevin Jessup, kevin.jessup@mixcom.mixcom.com "Friends don't let friends run DOS." -- Microware Thanks Again Kevin!

Rumor: may also enable cross-band repeat. 1. Turn power off. 2. Remove battery. 3. Unscrew stainless steel battery connector plate. This is the rectangular s/s plate found at the bottom of the unit and is held in place with (4) small chromed, phillips head screws. 4. Remove Antenna. 5. Unscrew the one black head, phillips head screw found immediately adjacent to the BNC. 6. Carefully remove the grey DIAL, UHF and VHF plastic knobs. 7. Unscrew the lock ring nuts that are found under each of the three sets of knobs. 8. Gently remove the plastic top cover on the unit. 9. Unscrew the (4) black head phillips screws that hold the body halves together. 10. Place the unit face down on a work surface that is covered with a towel or a similar soft cloth. This will protect the unit from being marred while you work on it. 11. Gently separate the two body halves about 1/2" to 3/4". 12. Cut the ORANGE wire loop and reseal the exposed ends with heat shrink tubing. (NOTE: if your DJ-560T is serial numbered from #0636-0705, the loop will be YELLOW in color! However which ever the color, cut only the loop! It will be the only loop to be found!) 13. Reassemble the unit in the reverse order of the above instructions. 14. Reset the CPU by holding the 'F' key (above the PTT key) down and turning on the unit. This mod was supplied by a major amateur radio dealer. Several have tried it and it works. One caution: The black screws that hold the back on are *real* cheeeep. Use a screw driver of exactly the right size or you're likely to strip the heads. ллллллллллллллллллллллллллллллллллллллллллллллллллллллллллллллллллллллллллллл ***************************************************************************** Path: cbfsb!att!linac!uwm.edu!zaphod.mps.ohio-state.edu!wupost!m.cs.uiuc.edu!vela!arga o.cs.oakland.edu!SDKUO From: sdkuo@argo.acs.oakland.edu (Steve Kuo) Newsgroups: rec.radio.amateur.misc Subject: Re: Alinco DJ-160T: DTMF decode works great, now what about mods?

A simple modification to the radio will enable it to transmit in the full range it receives currently. I have not tested the output power on other frequencies (Due to my one and only watt meter getting fried) however I have tried setting a weather receiver a small distance away, and I did hear the radio in the receiver. To make the mod, the following must be done: (I assume that you have some experience with electronics and that you can tell a wire from a resistor, from a transistor) 1) Take the battery of the radio by lifting the battery release button. If you look at the bottom of the radio, there will be a metal plate that is held on with 4 small screws. Take this plate off, noting exactly how the clip was held on (like the slot for the battery release clip) 2) On the back of the radio there are two screws that hold the back of the radio on, take these screws out. 3) Now you should be able to lift the bottom part of the radio by Enter=continua, A=Annulla (N=Prossimo C=Senza Paginatura) >>>the battery release button slightly apart. I was told that you should take the top knobs off, but I found that I didn't have to. 4) If you take the Battery Release Button and turn it about 90 degress, the button should come out easily. After you get the small piece of plastic that is the button, you should see a yellow wire behind where the clip was. 5) Take a small wire cutter and CUT this YELLOW wire. You should probably make sure that the wire doesn't have bare metal showing from a lousy cutter, because I don't think that grounding this wire to the case would be HEALTHY for your radio. :-) 6) After You cut this wire. Assemble the radio, and just before you turn on the radio, do a power reset by holding the FUNC button while turning on the radio. This will reset the radio to ALL of the factory set parameters. YOU WILL LOOSE PROGRAMMED FREQUENCIES that were programmed into the memory mode of the radio, so just write the frequencies down before proceding with the above instructions. 7) The radio should be just like new, except that the transmit will be enabled for ALL frequencies! GOOD Luck! If you use these mods for ILLEGAL purposes, pity upon thy sole, for you do not belong in the ranks of Amateur Radio. This information is only supplied for Legal and Informational Purposes only and I can NOT be held responsible for anything that you do with this INFO. And if you are an idiot and screw up your radio by your own stupididy, TOO BAD. I can't be held responsible for my own actions anyhow, so as Brian@ucsd.edu would say, "So There!" **************************************************************************** Name: Donald L.
