[Repeater-Builder] Voters
A while back, there was some discussion on voters. I have read through all of that. I am looking to install one here. I am planning on bringing my rx sites back on RF and having the rx radios at the voter site interface to a status tone (2175 Hz) circuit and then feed the voter. My question is: Does anyone have a circuit to generate the status tones or know of a reasonably priced commercially available product. I just don't want to re-invent the wheel if someone else has already dealt w/ this. Jamey Wright KD4SIY Yahoo!

[Repeater-Builder] Problems with Hamtronics Amp
I have a problem that is got me swamped. I converted a Hamtronics 2m amp into a 220 amp. Just followed the schematic and changed all the caps and redid the coils. Problem is that for 2 watts in I get 2 to 3 watts out. For a simple 1 transistor circuit it don't make sense. Even changed the transistor and no luck. Anyone have experience that could offer suggestions? Thank 73 Mark Yahoo!

[Repeater-Builder] Kenwood 850 UHF Power level
Considering replacing our UHF Hamtronics rx and tx with the Kenwood TKR850. Two questions (at this point): Can the output be turned down to 7-10 watts in the software; and should I be concerned about a sensitivity rating of .35uv compared to a measured .18uv on the Hamtronics? This is for the same quieting (12db). Or is it safe to assume that in the real world the Hamtronics' sensitivity falls to about .35uv with a stiff level of rf hitting it whereas the Kenwood may hold steady at .35uv? Thanks for the info!

Re: [Repeater-Builder] Voters
It doesnt require any mods to the voter. Use the radio links as conventional except for inserting idle tone from the link receiver when no signal is present,its easier than trying to keep link transmitters on 24/7,IMHO You can build a tone generator from a 555,lots of circuits around. And dont forget to add an identifier for each link transmitter. Lots of work to set up but worth it when you get it all working properly. - Original Message - From: Jamey Wright [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Tuesday, September 14, 2004 8:54 PM Subject: RE: [Repeater-Builder] Voters That way I don't have to do any major mods to the voter.

Re: [Repeater-Builder] DB-420B Element spacing
Optimum spacing center to center should be 0.85 to 0.95 wavelength. Sometimes a phasing harness won't allow you to get that far, so you do the best you can.

All of the spacings in the vertical plane between elements are different dimensions. So, I have a few questions: 1. Can anyone tell me what the center to center spacing is supposed to be? 2. Would it be of any benefit to change the spacing to reflect the lower operating frequency?

Re: [Repeater-Builder] Kenwood 850 UHF Power level
Michael, You pose a crucial question: Which is better, sensitivity or selectivity? The Kenwood TKR repeaters are at the low end of commercial-quality equipment. I invested in a Hamtronics UHF repeater, thinking it would be a way to obtain a high-quality repeater on a limited budget. Boy, was I wrong! Although it met all of its published specifications, I quickly discovered that the PA had no circuit to protect and/or regulate its power, there was no filter to eliminate the CTCSS tones from the audio, no courtesy beep, Morse ID was extra and NOT programmable, no capability for CDCSS, etc., etc. I discovered that a Motorola R1225 transceiver had everything I needed in a package that cost about 2/3 that of a Hamtronics repeater. Even when you add the $265 for the RSS to program the repeater, you are still money ahead, and have many more features and a lot of built-in protection. I will support and defend Hamtronics receivers as being well-built, economical, and sensitive, but their products seldom meet the stringent requirements of high-quality repeater components. Perhaps the lesson to be learned here is that light-weight, modest-quality equipment will seldom, if ever, perform to the expectations of those who require professional-quality performance! 73, Eric Lemmon WB6FLY Michael Singewald N1PLH wrote: Considering replacing our UHF Hamtronics rx and tx with the Kenwood TKR850.

RE: [Repeater-Builder] Kenwood 850 UHF Power level
First off yes, you can adjust the level to any drive power you want to drive an amplifier. We have put many in the field driving amps at ranges from 5 to 15 watts. As far as the sensitivity goes.the spec of .35 is conservative and usually is better, but what really helps is that the selectivity is very good on these units. You won't be sorry to toss out the Hamtronics for an 850. Gregg R.

Re: [Repeater-Builder] Voters
At 05:13 PM 9/14/04, you wrote: A while back, there was some discussion on voters. I have read through all of that. Have you read the two or three voter articles at www.repeater-builder.com on the Technical Info page? I am looking to install one here. For what reason? Some repeater systems that talk further then they can hear decide to add a voter system to try and match the coverage. Others add a voter to improve hand-held coverage inside the existing TX footprint, others just add a two channel voter at the main RX site to gain some diversity reception. What is your reason? I am planning on bringing my rx sites back on RF and having the rx radios at the voter site interface to a status tone (2175 Hz) circuit and then feed the voter. You are aware that the 2175 status tone is designed for a wired system? (where they bring the audio back on leased phone lines). And that doing it that way will require you to run the link TX on a 7x24 basis? This can get expensive in not only the power bill but in replacing links TXs (have you verified that you can get the link frequencies there - one per RX site?). Which band do you plan on using for the links? 420MHz, 900MHz or 1296mhz? What equipment do you plan on using for the main channel RXs and the link radios?? And do you have spares? Running a link TX 7x24x366 just to keep a tone decoder happy will quickly determine if your link system is continuous duty... My question is: Does anyone have a circuit to generate the status tones or know of a reasonably priced commercially available product. I just don't want to re-invent the wheel if someone else has already dealt w/ this. The GE voter used a 1950hz status tone and there was a board that fit into the EP-39 aux RX chassis that did just what you want. If someone can post that schematic all you need to do is change the cap in the oscillator to pick up the Moto tone frequency. There may be a Moto Spectra-Tac card that does the same thing but I am not aware of the card name or part number. And there are a lot more GE manuals on PDF floating around that there are Motorola If need be I have a simple audio oscillator design that I can email you that uses an 88mh toroid and a single transistor. My first voting panel used this tone gen feeding the normally closed contacts of the COR. The relay armature fed the link TX and the normally open contacts was the RX audio. A 10 second carrier delay relay filled in the gaps of tweak signal flutter. The link RX COR dropping out told the voting panel that the channel was idle. Jamey Wright KD4SIY Mike WA6ILQ Yahoo!

Over the next 14 months the repeater was back to Kenwood seven times and within hours of the time we would get it back each time it was dead again. Kenwood consistently refused to replace the unit with another one even though we knew that the one we kept getting was a lemon. Only after we finally threatened Kenwood with legal action did they finally send a new unit. Over the 14 months we actually owed the unit it spent a grand total of 2.5 hours on the air. I am the trustee of an Emergency Services group that had purchased the repeater and we needed it to work for more than just chit chat and you see the type of response we received from Kenwood. I can only say buyer beware when buying anything where you may need Kenwood to fix it or stand behind their warranty. The attitude we received was "It's yours now, you are on your own".

Re: [Repeater-Builder] Voters
The GE voter and M's voter both have COR input lines. The status tone is used when you have a continuous audio path between the voter and the voter Rx; Ex: Telephone lines/ Microwave Mux. When you use a keyed up link you normally would use the COR line to indicate status.

Re: [Repeater-Builder] Voters - STATUS TONE
Status tone does set the agc in the sqm. Very impotant when using phone lines with varying losses. When using rf links with fixed levels a simple mod makes the agc constant. Works great when using the cor mod. Yahoo!

RE: [Repeater-Builder] Kenwood Repeater
Steve I think you have more than a problem with Kenwoodit's either your dealer or the way the situation was handled. I was a Kenwood dealer for over 20 years (retired last year), and Kenwood was always responsive to our needs. I've had LEMONS from every manufacturer including Kenwood and never had a problem with them replacing the unitno matter what it wasif I said I wanted it exchanged..they exchanged it. There has been a lot of talk of buying from Kenwood Dealers that don't service their equipment but send it in to the Depot. Personally I would never deal with a company that didn't have the technical expertise to maintain and repair the equipment they sold. We always repaired all the equipment we sold IN HOUSE, except for DOA's which we promptly got an exchange for the unit or a credit to our account. So all of that saidI really don't think Kenwood was the problem.it was whoever was in-between and apparently whomever you purchased the unit from apparently is one of these companies that doesn't SERVICE WHAT THEY SELL. If they can't service it, then they shouldn't sell it..end of story. Gregg R.

Re: [Repeater-Builder] Voters
I have a bunch of the GE tone generator panels available if anyone needs any, most were used with various GE MASTR receivers. They're 19 rack-mount, about 1 high, they were used with a GE Voter so I belive they're currently setup for a 1950 Hz status tone.

I have read through all of that. Have you read the two or three voter articles at www.repeater-builder.com on the Technical Info page? I am looking to install one here. For what reason? Some repeater systems that talk further then they can hear decide to add a voter system to try and match the coverage. Others add a voter to improve hand-held coverage inside the existing TX footprint, others just add a two channel voter at the main RX site to gain some diversity reception. What is your reason? I am planning on bringing my rx sites back on RF and having the rx radios at the voter site interface to a status tone (2175 Hz) circuit and then feed the voter. You are aware that the 2175 status tone is designed for a wired system? (where they bring the audio back on leased phone lines). And that doing it that way will require you to run the link TX on a 7x24 basis? This can get expensive in not only the power bill but in replacing links TXs (have you verified that you can get the link frequencies there - one per RX site?). Which band do you plan on using for the links? 420MHz, 900MHz or 1296mhz? What equipment do you plan on using for the main channel RXs and the link radios?? And do you have spares? Running a link TX 7x24x366 just to keep a tone decoder happy will quickly determine if your link system is continuous duty... My question is: Does anyone have a circuit to generate the status tones or know of a reasonably priced commercially available product. I just don't want to re-invent the wheel if someone else has already dealt w/ this. The GE voter used a 1950hz status tone and there was a board that fit into the EP-39 aux RX chassis that did just what you want. If someone can post that schematic all you need to do is change the cap in the oscillator to pick up the Moto tone frequency. There may be a Moto Spectra-Tac card that does the same thing but I am not aware of the card name or part number. And there are a lot more GE manuals on PDF floating around that there are Motorola If need be I have a simple audio oscillator design that I can email you that uses an 88mh toroid and a single transistor. My first voting panel used this tone gen feeding the normally closed contacts of the COR. The relay armature fed the link TX and the normally open contacts was the RX audio. A 10 second carrier delay relay filled in the gaps of tweak signal flutter. The link RX COR dropping out told the voting panel that the channel was idle. Jamey Wright KD4SIY Mike WA6ILQ Yahoo!

Re: [Repeater-Builder] Kenwood Repeater
In response to some of the earlier posts regarding Kenwood versus Hamtronics and then this post, I certainly hope the Captain is not thinking that Hamtronics will do anything for the end-user that is even close to what he summarizes here where Kenwood replaced the rig. I have bought new Hamtronics that never ever performed in a manner that would be legal to operate on any band.

Re: [Repeater-Builder] Voters - STATUS TONE
With all the talk of voters I thought I might as well throw in my voter question. I was wondering if anyone knows if themotorola Digi-Tac comparitor also has a cor input line asit was said that theSpectra-Tac did. I have a Digi-Tac here with abad power supply board I would like to put into use. It was used with the dedicated phone lines and is set up for 2175 status tone right now. I would like to do rf links and use cor to show activity, but didn't know if it was possible. If it is then it might be worth my fixing the power supply in this unit. T.J.

RE: [Repeater-Builder] Hurricanes and news centers
Please excuse my request, being off topic, but it is relative to towers (which could affect repeaters in Colorado). May I make a request of ALL of those who have good coverage, or even spotty coverage, could you make a note of which stations or papers they are and send me the contact information for those stations/publications. They generally require date and times or at least close to get tapes of the segments, so that would be of a great help. Additionally if you have newspaper articles or see them, ir you could save and send them to me or let me know what date, publication name, page number, we can take that opportunity to gather those to aid in our project. I would not ask you necessarily to make contact to get copies of the footage/spots, but this could be very useful in a local battle in Colorado for tower legislation. Thanks, Randy, W0AVV Yahoo!

Re: [Repeater-Builder] Hurricanes and news centers
When I was in Ft. Worth last June during the severe thunderstorms flooding there, the local TV news broadcasts gave out the 2 meter repeater frequencies used for the local Skywarn nets as places to get the latest info on the storms. We don't seem to get that kind of media exposure here in SoCal, probably because we don't have severe weather like other parts of the country. Bob NO6B Yahoo!

RE: [Repeater-Builder] Hurricanes and news centers
Bob, That is probably due to a long time Fort Worth based weather man legend, Harold Taft. He was one of the pioneers in weather forecasting that worked at the first TV station in Fort Worth and later when it became KXAS. He was the first to get involved with Ham radio operators supporting the local SkyWarn service. He was adamant about only giving a forecast of no more than 3 days ahead. Sorry to say Harold passed away about ten years ago. He did leave a legacy at the TV station. It was also a tradition for him to play his trumpet to start the yearly Mayfest tug-of-war across the Trinity river!
