Re: [Repeater-Builder] Help needed
Makes a lot of sense, but the gentleman who has offered them to us is in the business. We will be hanging our new repeater on a commercial tower he owns. The unit is a base unit, is in working condition and he has offered to tune it and the duplexers we hope to obtain, for free. Can't beat the price. I am handicapped at this time as he is out of state for a few days and we haven't seen the equipment. I believe I have the answer on the crystal units, however, as I'm told we can use the existing element, just replacing the crystal and getting it tuned and adjusted for the new crystal. I guess we're down to getting the best possible offer on the duplexers.

Re: [Repeater-Builder] Re: TKR-740 versus TKR-750 (Was: Maggiore's Service)
Coy: Hi-Q active detectors here refer to RC and high Beta transistor networks that were first used in GE Mastr Pro in the last few years of production and then in Mastr II with the versa-tone networks that were laser trimmed Resistor networks and Op Amps mounted on ceramic substrate. They all made Hi-Q circuits that could either generate a CTCSS tone or provide for the detection of a very narrow band of audio frequencies for CTCSS. You are correct in that the original reverse burst was 180 degrees that tried to stop the vibrating of the mechanical reeds. However, even with mechanical reeds 180 degrees was not the best phase reversal, but it was the cheapest to do. When Mastr II was designed it was decided to use the ideal amount of phase reversal of the CTCSS tone, as it was not 180 degrees and this has continued into today. I would invite you to look into any design on tone detection circuit design, you will find that there is no instantaneous off when the tone quits, be it mechanical, solid state RC, phase detector, or other types. Some phase reversal is needed to turn the detector off if you want as fast a response as can be obtained.

The design of the solid state detector dictates the amount of phase shift of the CTCSS tone that is ideal to stop the ring down of the Hi-Q networks.

[Repeater-Builder] Reverse Burst (Was: TKR-740 versus TKR-750)
I have changed the subject of this thread, since it now has nothing to do with TKR repeaters. TIA/EIA-603-B, the international standard of the Land Mobile Radio industry, defines two STANDARD formats for CTCSS Reverse Burst: 1) A shift of 180 degrees for 150 milliseconds; and 2) A shift of 120 degrees for 180 milliseconds. It happens that Motorola embraces the 120 degree (same as 240 degree) shift, while almost all other manufacturers use the 180 degree shift. Motorola adopted the 120 degree shift because they found that it stopped the vibrating reed of a Vibrasponder module in less time than a 180 degree shift. While I intuitively feel that a 180 degree shift would be more effective than a 120 degree shift, I am not going to start a debate on the pros and cons of one shift over the other. I reported as a fact that there are TWO formats, and that is not open to debate. Now that the decoding of CTCSS reverse burst is done within a DSP audio processing chip instead of a mechanical reed, in almost all modern radios, the manufacturers can fine-tune the timing and phase detection circuits so that they can discriminate between a 180 degree shift and a 120 degree shift. I have already experienced the incompatibility between Kenwood and Motorola reverse burst formats. My solution was to convert the entire fleet to CDCSS, since there is only ONE format for digital coded squelch, and I can mix Kenwood with Motorola radios and have them encode and decode CDCSS in harmony. The practical consequence of this CTCSS Reverse Burst incompatibility is that modern Motorola radio systems will not mute silently with Kenwood and other brands, and vice versa. While it may be argued that the top LMR brands are using this incompatibility as a marketing tool, I think it is unfortunate that there is no move to have but one reverse burst format. One of the reasons I bought a Motorola HT1250 UHF radio for my public-safety work is that it is one of the very few radios, and perhaps the only one, that can be programmed for either of the two reverse-burst formats, on a per-channel basis. The Advanced tab of the Conventional Personality page has a box labeled Non-Standard Reverse Burst. If this box is unchecked- its default condition- that channel will encode and decode CTCSS reverse burst in the Motorola format. However, if this box is checked, that channel will encode and decode CTCSS reverse burst in the Kenwood and rest-of-the-world format. This is a boon for anyone who uses more than one repeater system! I have one radio that can mute silently when talking through the Motorola repeater used by the County, and also mute silently when talking through the Kenwood repeater used by the City. To the best of my knowledge, this capability is only available on the portable and mobile radios in the Professional series. I expect Kenwood to follow suit in the near future! 73, Eric Lemmon WB6FLY Fred Seamans wrote: Coy: Hi-Q active detectors here refer to RC and high Beta transistor networks that were first used in GE Mastr Pro in the last few years of production and then in Mastr II with the versa-tone networks that were laser trimmed Resistor networks and Op Amps mounted on ceramic substrate.

[Repeater-Builder] WA6SVT coaxial collinear results
Recently when I said I was building one of these, some folks wanted my evaluation of it when it was completed. I've misplaced your emails (I hate when that happens!) so will post it here and hope Kevin doesn't mind. I built a 10 element UHF version. One minor concern: I couldn't change the SWR at all by moving the decoupling sleeve up or down. However, it's OK since the SWR minimum is exactly on my design frequency. Impressive. I was actually shocked to find the SWR did not change appreciably between top mounting, side mounting at 1/2 or 1/4 wavelength. I expected it to complain about the nearby tower when side mounted. It doesn't even seem to notice. Unfortunately I don't have much to compare its performance to. The previous antenna was a Cushcraft 4-pole dummy load at the same height. The coaxial collinear provides MUCH better coverage (no surprise there BIG grin). I have a VHF repeater at the same site (1 dB less power into a 5 dB gain commercial StationMaster). Over flat terrain VHF and UHF coverage is very nearly identical. In rolling hills VHF is generally better, as you might expect. In mountainous terrain VHF sometimes has the edge, other spots the UHF wins hands down. I wish I could offer more meaningful comparisons. I'm quite happy with it and plan to build more of them for other sites and applications. Paul N1BUG Yahoo!

Re: [Repeater-Builder] DB264-A vs -C dimensions
Between 0.85 to 0.95 wavelength, center to center.

I looked up the physical specs and found the mast is the same length (258) for the A, B, and C ranges. So I may be able to drill some new holes, plug some old ones and get away with it. I'd like to know for certain if they used wider spacing before I dig too far into this.

[Repeater-Builder] Re: Kenwood TKR-850K3 Help
Hi There, not that easy as the UK / European band is 430 to 440 Mhz and there is no TKR-850 that covers it. THe software keeps saying it's RX Frequency is out of Range and the same for the TX Frequency ? If you could give me a detailed pointer as to what I have to do it will be most welcome. Thank you.

RE: [Repeater-Builder] Re: Kenwood TKR-850K3 Help
Don't select that model from the list. Start fresh with the software on the freq range that you want. Then when you write the radio it'll ask if you want to change models. Say yes and it should go.

Re: [Repeater-Builder] DB264-A vs -C dimensions
I don't think that experimentation is the wrong thing to do, as long as your expectations allow for possible failure. It's in true ham radio spirit to try to do what some consider the impossible or foolish. I've failed many times trying to save a buck but the educational part of experimentation always paid off. This separates the experimenters from the appliance operators. 73, Joe, K1ike PS: I have heard that you can lengthen the loops by simply adding a long screw to each end of the loops. This changes the physical length of the loop to the proper dimensions. --- Paul Kelley [EMAIL PROTECTED] wrote: OK, I know the major response to this is going to be forget it and buy the right antenna. but I will blunder in and ask this anyway.

Re: [Repeater-Builder] WA6SVT coaxial collinear results
