[Repeater-Builder] OT- More comms in movies
I was watching Dark Knight (The new batman Movie) last night, which was filmed partly in Chicago, and there is a scene where Batman is standing on top of one of the roof decks on the Sears Tower (North Side of the tower). In that scene you get a great shot of the antenna mounting grid with all the fiberglass sticks and one lone DB-420 (or what looks to be one) on the corner right by Batman. Kinda neat to see- just be careful when you pause it to see- Your significant other may roll their eyes at you! At least mine did Tom W9SRV

[Repeater-Builder] Icom Repeater to External Controller connections
va3rzs va3r...@... wrote: Looking to put the 220 repeater on the controller has any one done this ? Thanks for any and all help Rick I've seen external repeater controller connections made on/to Icom Repeaters in a number of different ways... and of course it depends what the model number and era the repeater was made. The early Icom Amateur Repeaters are defined by me to be the ones with small on board uP controllers, which require Eprom programming for the IDer. And I've seen two different versions of the early Eprom Icom Repeater Controller boards. *The processor chip defines the Eprom size and ID programming location. I can, do and have reprogramed the Eprom ID chip information to/for anyone willing to pay the return postage. In some models/versions the early repeaters are crystal frequency based and the offset in the case of the 1290MHz units was not changed without a modification (which I was told is/was available). Later Icom Repeaters had synthesized frequency and ID setup (programming) via dip switches and a few other hoops. Interface on the late Icom Repeaters was easier to some degree as there was an interface jack built right into/onto the back of the cabinet. I've seen two external controller interface methods applied to the Icom Repeaters. The first was to completely disable the internal (early) uP Board COR/COS logic and make most of the connections to the audio RF and cos there/nearby. Depending on who's mod I've seen... sometimes the original tech would install interface transistors/fets at logic locations coming right off what I consider critical part locations. These buffer/inverter devices (transistors/fets) were used to isolate the direct uP chip output logic line for CTCSS and or COS. Just depended on what controller was in the repeater and who was doing the mod. I haven't seen a super clean mod for the older repeaters but everyone I've been exposed to (so far) didn't break anything (cause a failure). I looked around the RB site for this subject information and there is surprisingly little around (yet). I'll continue to look around and I do still have one of those modified Icom (early) repeaters on the shelf. The $%^#*@ synthesizers crapped out on two repeaters I have here and of course you can't get parts to fix them. back after this commercial message... cheers, skipp
[Repeater-Builder] Simple Emergency Repeater Idea
I am not sure if this would work. You have 2 handhelds with remote PTT jacks on it. Set Radio 1 to the Input freq Set Radio 2 to the Output Freq Take the audio from Radio 1 out jack for the external earpiece and put it to the small jack on the output freq. In theory it should key the out put radio to rebroadcast the signal. my MP3 player has a record feature that will allow you to go from the head phone size jack to the smaller jack. I am going to have to try it when I have some time, but any thoughts on this?
[Repeater-Builder] Motorola RSS File Structure
In possibly what may be the most blindingly dump question ever posted here, but has there ever been a deconstruction of the codeplug files for Motorola's HT600, P200, and MT1000 radios? Please know that I am NOT asking for RSS nor am I asking for copyrighted or patented material from Motorola. Nor am I asking that anything be sent to me. I am wondering if anyone has reverese-engineered the codeplug structure and posted it. Again, this request should be in NO WAY construed as a solicitation for intellectual property, material, or product. Thanks in advance for any comments, W. H. Phinizy, k6whp
[Repeater-Builder] Re: Notching nearby frequencies
Ian, What you would like to do is not difficult just may be expensive if you do not have the filters you would need. You described your situation as you want to receive on 479.350 and you have a link transmitter on 481.825 on the same or nearby antenna. As the 481.825 is a link transmitter you may have better luck putting a Notch filter on the output of the 481.825 that would notch the 479.350 signal away from 481.825. You could stand to loose a few DB on the transmit unless you have a broad notch filter which would mean you may need more than one to tighten your notch in favor of 479.350 and allow more pass of the 481.825. This may mean more insertion loss for the 481 transmit so as long as you can stand to loose the signal then that should adjust the interfering frequency better. As a note you can use Pass as long as there is enough of it and these get expensive.

I currently have between the diplexer and the 479.350 receiver -a band pass cavity tuned to 479.350 and a notch diplexer tuned to notch the 481.825 . I am concerned that this is reducing the receiver sensitivity and feel I would be better to have the band pass between the diplexer and receiver and using a t piece connect the notch to the t piece Current setup Diplexer--band pass cavitynotch diplexerreceiver Proposed setup Diplexer -- band pass cavity ---t piece receiver Notch I will try the proposed setup shortly on on a hp service monitor to see if I am better this way Thank You, Ian Wells, Kerinvale Comaudio, 361 Camboon Road.Biloela.4715 Phone 0749922574 or 0409159932 www.kerinvalecomaudio.com.au

[Repeater-Builder] 220mhz repeater for sale
I have a complete 220mhz repeater for sale. It is a converted Motorola Micor running 50 watts. Also includes a 4 can set of cavities, a RC-100 controller, a Isolator on the output, and a brand new in the package 220 fiberglass antenna that I never installed. NO power supply. every thing is mounted to a homemade card that can be wheeled around for service. I absolutly will NOT ship this. Pick up only or will meet within 100 miles of Chandler AZ. Also have a copy of the manual for the controller. All you need is a site, feedline and reprogram the ID and you are on the air. Crystalled on 224.98 and coordinated in AZ. Asking $700 for the package. I can also offer a GE MASTR II 30 amp power supply for an addtional $40 I have too many repeaters sitting around here. I already have 3 on the air. I also have a Kenwood TKR-820 UHF repeater with internal duplexer and ID-8 ider. It is programmed and tuned on 446.575/PL 100hz, 12 watts out of the duplexers. I would take $500 for the 820 shipped to the lower 48 only. Respond off list to my email only n0...@cox.net Thanks for the bandwidth. dan/N0FPE

Phinizy, k6whp Funny you should ask about the Genesis radios. They are the only code plugs that I've really looked closely at. The HT600 and P200 (except low band) are the same radio. The HT600E, MT1000 and low band P200 are the same radio. I have no knowledge of the HT600 code plug, but the MT1000 code plug is straight ASCII text characters that are positioned at specific byte locations in the code plug. My interest in cracking the code plug is because I have several MT1000s - a 16 channel UHF on GMRS, a 99-channel UHF on mixed use, a 99 channel high band that is loaned out, probably never to be seen again (the guy dropped out of sight), and a 99-channel low band 42-50 MHz version that I'm still trying to move to 6m while maintaining sufficient RF bandwidth to do both 47 MHz Red Cross and 52-53 MHz amateur repeaters (yes, it will take two different antennas). In other words, 42-50 will preferably become 46-54, but I'll settle for 47-54. Once I figured out enough of the format that I was convinced that I could use Notepad as an editor I lost interest in going any further. I've taken a UHF MT100 code plug and edited it to move blocks of frequencies around. The radio started out as a mix of channels and I eventually ended up with amateur simplex at the low end, open repeaters above that, closed repeaters above that, and the last 10 channels were GMRS. I simply limited my edits to line 15 and down, moved the blocks and fixed the first four characters on leach line. A year or so later a friend heard about my efforts and sent me his cheat sheet, that I combined with my notes to produce the test below. Mike WA6ILQ Here's the MT1000 code plug Rosetta Stone: I have two 99-channel UHF radios. This may not be relevant on 6, 8 or 16 channel radios. First open the code plug file in a plain text editor WITH ANY WORD WRAP / LINE WRAP TURNED OFF. Some of the lines are longer than 80 characters and YOU MUST NOT DISTURB THEM.

I've not tried any others. Unless you need it avoid channel 88 as the radio displays an 88 as an error code.
