Re: [Repeater-Builder] Diamond X-500 for repeater use?
I have 3 diamond hnaX510's and consistantly can reach about 75-100 miles in every direction with the antenna about 30 foot to the bottom of it, (roof mounted) I compared it to a 8 element beam and it was almost the same signal strength as the beam except it worked in all directions. I have never had one come loose in the sections or burn up. I regularly run 70 watts max. I am in richmond and can hear repeaters in MD and WV. I duplexed mine on 441-446 split at about 20 watts without problems. cant hurt to try it. George KF7NN - Original Message - From: Derek B.

My guess is it's rated in dBi, therefore, the claim may be a little closer to realistic.. 5 dBd on 2M and 8 dBd on 440 is my guess.. The power rating says 200 watts. I once saw a Comet GP-6 whose power rating also said 200 watts but in the fine print, I saw the PEP rating beside it.. it was rated in SSB, which of course, we normally do not use vertical antennas for SSB in those portions on the ham band.

I am looking for overall performance opinions on the Diamond X-500 for serious repeater use and if there's a better dual bander out there with relatively high gain, tell me what it is. I'll be running about 60 watts on VHF and 75 watts UHF into the antenna (after feedline losses).. Thanks, Derek KC4FWC http://www.w4dex.com/kc4fwc/ Yahoo!

Good morning all.. Our Assoc. (www.n4nw.org) runs the X500's on both of our sites. I have done the dis-assemble, and reliability mods discussed earlier.

Good morning to all. Here is my .02 I have had several X-500's in use at heavily congested sites without I/M problems. However, they WILL burn up if you crank 200 watts (100 Vhf and 100 Uhf at the same time) into them for any length of time. They WILL draw moisture without extra sealing precautions, and, if used at a site with a large HAAT, the low angle of radiation becomes really obvious for the users close in and under the antenna. The radiation pattern is FULL of holes. It has been my experience that a user 2.5 miles away, LOS, 600 feet below the antenna, has far less signal strength than other many miles away, LOS. My chioce regarding the Ham antennas for duplex use has to be the Diamond X-50. They just take a licking and keep on ticking.

Re: [Re: [Repeater-Builder] Diamond X-500 for repeater use?]
Hello, For my own repeaters,I use only professionnal antennas.Here,in France it's easy to find in some flea markets or from a friend old professionnal antennas.Depending of the origin,it cost from a french wine bottle to about 60 Euros. The main reasons,except cheaper price,for the use of this type of antenna are the followings: -It's invisible on a tower.Nobody knows if it's amateur or professionnal. -I know the real characteristic of this antenna(real gain,max. power,beamwidth in E and H,SWR,IMD...).Amateur antennas are not characterized. -Quality of components(fiberglass,stainless steel) and reliability . -Beamwidth are easy to modify if you get dipoles or panels of dipoles. -Mast mountings are in wide diameter. I use to install Kathrein(the best),Mat equipement,Sinclair,Sigma antennas.

Re: [Repeater-Builder] TS-64 Reverse Burst
[EMAIL PROTECTED] wrote: Hi Eric, Reverse burst is one of my favorite topics! The TS-64 is probably designed to operate on the more common of the two standard reverse burst formats, privately referred to as Kenwood and the Rest of the World format. This format shifts the phase of the CTCSS tone by 180 degrees for about 150 milliseconds. The other format, used exclusively by Motorola, shifts the CTCSS tone phase by 120 degrees for about 180 milliseconds. Interesting, thanks for the background info! We also noted that the TS-64 reverse burst does indeed turn off a TS-64 decoder quickly, but the TS-64 reverse burst has little effect on a TS-32 decoder. This leads to the conclusion that reverse burst only has an effect on filter-type decoders, not counting-type decoders. Would you agree with that? 73, Bob My experience is that the TS-32 does not respond to reverse burst in any format, although some will partially mute on reed-tpye encoders, like a Micor.

Re: [Repeater-Builder] De-Emphasis from Discriminator Audio
From: Kevin Custer [EMAIL PROTECTED] My suggestion for properly de-emphasizing repeater audio is to use this circuit: http://www.n1uec.org/n1uec/deemphasis.html I suggest that a small value resistor (220 ohm or so) be added to the output to prevent any capacitive loading of the op amp. Some op amps will oscillate with as little as 100 pF across their output. This small amount of capacitance is easily built up over just a few feet of shielded audio cable. If the op amp breaks into oscillation, it will probably be ultrasonic so you wouldn't be able to tell without a scope that anything was wrong. But if the circuit directly feeds into a modulator, the resulting spurious emissions would be significant, to say the least. Bob NO6B Yahoo!

Re: [Repeater-Builder] Digest Number 2277
Hi Skip025, Yeah, potting material makes it difficult to find out what's inside, but you could just buzz out the connector for the wire jumpers between these pins if you cared to. I, too, have made many adapters to use with my KPG4 clone. Even did a King mobile with it. Now I'm trying to find the pinout on the EF Johnson Challenger to make an adapter for that. Got the schematic but the pins aren't clear as it is a double sided PC board connection. I added an LED and a 9 volt connector to mine. The LED lets me know it's getting power and the battery supplies power when programming portables that don't have the power pin or mobiles that may have the internal resistor (fuse) blown on the +12 line. I have not wanted to try drawing power off the computer. There are just too many variables there depending on how much current individual computers can supply through the RS232 port pins. Guess, I have not noticed any RF interference from the MAX232 chip version but then I don't have any AM radios in the shop.

[Repeater-Builder] Solving PLL Lock Problems with GE Ranger Delta Radios
SOLVING PLL LOCK PROBLEMS WITH GE RANGER DELTA RADIOS by K9KA = Recently I built a parallel port programmer for the X2212 memory chip used in GE Ranger, Delta, and Phoenix radios. I have been using Niles software to read and create files for the radios and KA9FUR's Windows program to read and write files to the EEPROM. After doing this I found that a VHF Delta SX radio had a receiver PLL lock problem that turning the PLL adjust would not fix on all the frequencies I wanted in the 2 meter band. I just had a similar problem with a VHF Ranger radio, but in this case neither TX or RX PLLs would lock in the ham bands. Here is a description of how I solved these problems for others, whom I sure will find the same problem. 1.) First check out the radio in the design frequency range. A good way to do this is to program in frequencies in 5 or 10 Mhz steps across the band and into the ham band; 170, 160, 150, 148, 146, and 144 Mhz for example. With these frequencies programmed start at 170 Mhz and check RX and TX lock on each channel. I found with my recent Ranger radio that I only had lock on 170 and 160 Mhz!! Next switch to the highest frequency where there is no lock (LED comes on) and try the PLL adjustment to see if you can get it to lock. You can try to walk your way down in frequency and see how low it will go. Do this on both TX and RX. 2.) Next I removed the PLL board from the radio and look first on the topside at where the PLL adjuster is. Then locate the connections for the coil or capacitor adjustment. In the case of a coil (the Delta) I added a small NPO ceramic or dipped mica capacitor across the coil on the backside of the PC board. In the case of a trimmer capacitor the padding capacitor is placed directly across the trimmer on the backside. Use short leads on the the added capacitor and locate it close to the adjuster. You must also avoid hitting support posts on the chassis that the board mounts on. I had this problem at first on the Ranger. 3.) Now re-install the PLL board and re-test for PLL lock in TX and RX as in (1.) above. If you still do not cannot cover the desired frequency range, re-adjust the size of the added capacitor until you do. For example, the Ranger required 3.6 pf on RX and 5.1 pf on TX. Once you get lock on both TX and RX across your desired range, you can re-program the X2212 for the 16 desired frequencies and begin using your new radio. Good Luck. 73, John, K9KA Yahoo!

Re: [Repeater-Builder] TS-64 Reverse Burst
Eric and all, Reverse burst is one of my favorite topics! The TS-64 is probably designed to operate on the more common of the two standard reverse burst formats, privately referred to as "Kenwood and the Rest of the World" format. This format shifts the phase of the CTCSS tone by 180 degrees for about 150 milliseconds. The other format, used exclusively by Motorola, shifts the CTCSS tone phase by 120 degrees for about 180 milliseconds. We pulled out the ol' Micor manual and took a look at the reed circuits. The reverse burst phase shift might more accurately be called a 240-degree phase shift because it's caused by the reed inductor and a series resistance that keeps the Q high. The encoder likewise generates a 240-degree phase shift with the reed inductor and an switchable RC circuit. No guess as to whether this was done intentionally to make it different from competitors or that was simply the phase shift that resulted from that particular design. It's interesting to hear that the 240-degree and 180-degree systems are so incompatible. Since the TS-32 is no longer made (which didn't encode reverse burst or shorten its decode time on receipt of reverse burst), and the TS-64 is its replacement (which does handle RB both directions), it would appear that 180-degree RB has become a desirable feature in aftermarket CTCSS modules. 73, Bob, WA9FBO Yahoo!

Re: [Repeater-Builder] Interesting scam
when i worked at Collins radio in texas they spend a fortune to develop a secure terminal with super high encryption on the connection and the data terminal itself BUT there was this guy that took it upon himself to build a receiver that could pick up the signals going to the moinitor and redisplay it on his monitor as he pushed it around the tech floor showing how secure their terminal really was. some thought it was funny others did not since he just defeated their 20 million dollar encrypted terminal with a cheap receiver and monitor. He now works in their encryption department. - Original Message - From: Gregg Lengling [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Monday, December 22, 2003 5:54 PM Subject: RE: [Repeater-Builder] Interesting scam This is nothing new, SIGINT, signals intelligence divisions with the US and British government and I'm sure others have been doing this for years.

[Repeater-Builder] repelacing antenna.
greetings.. i want to replace a g7-144 antenna. have lost 4 of them over the years from lighting.. looking at the celwave catalog. the PD654 is 2 PD340's on the same feedline giveing you a 8 bay dipole. question is... what matching/coupling has to be in order to do this trick... how much will i gain using 2 instead of 1 of these antennas..

Re: [Repeater-Builder] Diamond X-500 for repeater use?
I have 3 diamond hnaX510's and consistantly can reach about 75-100 miles in every direction with the antenna about 30 foot to the bottom of it, (roof mounted) I compared it to a 8 element beam and it was almost the same signal strength as the beam except it worked in all directions. Sounds like you need to throw the beam away and get a good beam... Sort of like the old Chris Craft 11 element beams were not hitting on much. A deacent colinear would usually match them. Yahoo!

Re: [Repeater-Builder] TS-64 Reverse Burst
And the other side of the coin -- press the PTT and then talk. All too often one hears a user (ham and commercial) begin talking before they have pressed the PTT. And it's even worse if there's CTCSS involved on both the repeater and the users radios -- add the time for two decoders to kick in. I keep telling the guys at work to press the mic, take a breath, then talk -- yet I might as well be explaining this to my wastepaper basket ;-) Chuck WB2EDV - Original Message - From: Thomas Oliver [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Monday, December 22, 2003 9:38 PM Subject: Re: [Repeater-Builder] TS-64 Reverse Burst You don't need a courtesy tone with a long squelch crash. tom n8ies Yahoo!

[Repeater-Builder] Manual Needed
OK, no laughing I have been blessed with about 15-20 Redicom MX80T 35S radios. As I understand it, these radios when originally designed were in the 900 MHz range and down banded for use in the US. I want to explore the possibility of converting them to 900 RX for repeater use and maybe even use as link radios or even 900 MHz repeaters. What I do not have is the maintenance manual. Some of the radios are already setup for full duplex. If anyone can help me in my search please let me know and we can work out the rest off list. I know they are rock bound but what the heck, it might be fun and I have plenty of time on my hands recovering from a 10 week stay in the hospital caused by a tower collapse on Oct 4th. And yes, I was on the tower when it fell over. 73's Robin N7XGG Yahoo!

Re: [Repeater-Builder] repelacing antenna.
You will gain 3 dB that most likely will never be noticed by your users. You will add the need to place additional supports. You'll narrow the beamwidth which may cause close-in coverage problems. It will add to your cost. I'd personally stick with the 4-element version.

[Repeater-Builder] GE Mastr II Audio Problem

However when I enabled the local speaker, it caused a feedback type howl on receive. As I decrease the volume on the local speaker it gets worse, and the only way to keep it out at all is full volume on the local speaker.

How do you have it connected? On either the base or mobile version, it should connect with an RCA jack. This is a repeater chassis, the 40 watt PA, and the RF leaves the PA board and goes to the filter board via a small coax soldered on both ends, it's the standard set up.

I'm assuming that the design is such that the thing will run normally with the speaker disabled, I'll have to trace the thing out to see if the switch that disables the speaker puts a load across the audio amp.
