Hi Givan, I saw your name pop up here on the repeater list and thought I'd try and contact you this way. I have been emailing you, unsuccessfully, to obtain the programming software and information for the GP68 plus radios that you offered me some time back. Perhaps my emails did not get through? Can you still help me here?

RE: [Repeater-Builder] Deltas as repeaters and Channel Guard thoughts.
Being new to repeaters, I've been doing a lot of research and reading though the LBI's available in repeater-builder.com (thank you to all who contributed, btw). I have learned LOTS. For my first VHF learning repeater I plan to use a couple GE Deltas (an SX for transmit and an S for receive due to the helical filters). First question: has anyone experienced issues with turning the PA on the 110-Watt delta transmitter down to 50 to 60 Watts with a fan for full duty cycle? I'm concerned with spurs of course. The Delta-S's, both on highband and UHF, seem to be very stable at any power level. I've had issues with lowband Delta-S's programmed at the high end of 6m (52/53 MHz pairs) sometimes getting unstable at certain power levels. However, even with the TPO turned down, there are still thermal issues. You're better off with a low-power radio (or even better, putting a low-power PA in a high-power chassis to take advantage of the bigger heatsink). or advice to give? I don't mind learning from my mistakes, but I'd rather learn from others'. :) If you haven't already found it, go to http://www.ka9fur.net/delta/delta.html for additional info beyond what is on repeater-builder.com. Some of it is specific to UHF, but there is a lot of good general info there, including dissection of the EEPROM storage format. Secondly, more often than not I have read that people toss the Channel Guard boards in these radios for HAM use. Why is that? I don't know, I've never heard of anyone doing that. The software decoder in the Delta-S is very good. Anyone actually use the board for tone squelch? Most definately. You can I'm curious why someone would go with something like a TS- 64 when the CG board accomplishes the same task. I don't know, the ComSpec PL boards aren't the greatest as far as decode performance, and the encoders have higher THD than most other designs. Incidentally, I am considering replacing the micro/prom in the Delta with a micro of my own (I fancy the Atmel line, though any would do.) While we haven't totally replaced the uP, Dave (KA9FUR) and I have come up with some software mods to facilitate customization of radios for non-standard uses such as locking to external frequency references (for simulcasting) among other things. Finding windowed (EPROM) parts (8749H) is getting difficult though. As you can tell I'm loving these radios (and similarly, the Phoenixes) so far... They're great radios. The Delta-S front end is very good, and is virtually identical to the front end in GE Mastr III's. Transmitters are extremely clean with low phase/sideband noise. I was told that the design criteria of the Delta-S/SX series included the requirement that sideband noise was to be less than current protection crystal-based transmitters (at the time, Mastr II series), and from all indications, they have exceeded that specification. Duplex operation on 2m seems to be comparable to the Mastr II PLL exciter, which represents about a 22 dB reduction in noise over the standard multiplier Mastr II exciter at 600 kHz T/R spacing. --- Jeff Jeff DePolo WN3A - [EMAIL PROTECTED] Broadcast and Communications Consultant -- No virus found in this outgoing message.

Re: [Repeater-Builder] Re: 6mtr duplexer
Al, Using 3 1/8 Heliax is approaching the proper length to diameter ratio for optimum Q which should provide a deeper notch and increase the total isolation. It may even be enough to eliminate one cavity per leg. All of the designs I've seen use the foam type, I doubt the air line insulator supports will provide enough mechanical stability.

Most of the discussion I've seen for the 6 meter Heliax duplexer has been centered around using 1 5/8 Heliax. Has anyone used 3 1/8 stuff? Probably not yet. Would there be any advantage to using the larger size? I have some available. Yes, higher Q = better performance. Has anyone used the foam 1 5/8 instead of air line for a duplexer? Yes, both work very well. Both have their advantages although I prefer the new teflon/delrin spiral spaced air line for ease of construction. Thanks, Al, K9SI We use the various types of hard line based on availability of surplus line. Getting above 1-1/4 inch hard line is typical for the relm of Broadcast Feed-Line Applications.

Re: [Repeater-Builder] deviation meter info needed
I wouldn't be surprised if Ted (MDM Radio) has a manual for it. It's probably what Heathkit copied for their dev'n meter. Basically a 25-50 MHz VFO and an IF strip with a calibrated meter, if it's the one I'm thinking of. If that's what it is, apply a signal and tune the VFO to a sub-harmonic for maximum peak with the meter in a tune position, then switch to read the deviation. If there's a 2 kHz position, it might (like the Heathkit) put a low-pass filter in the audio stage just so it primarily reads PL. Depending on how you tune the VFO, you will find two signal peaks, so you can read positive or negative deviation. Edison is probably the company name that took over Measurements corp; they were both out of Boonton NJ and made a lot of stuff that Motorola sold, including a matching signal generator. Of course I could be 100% wrong, too. Bob M. == --- Mike Perryman [EMAIL PROTECTED] wrote: Hi folks, I have an interesting beastie here that I am trying to locate information on.

The heliax notches do workquite well, but they are most certainly not plug-n-play. 1) You must pay strict attention to the design criteria, maximum performance is obtained with repeated efforts. Resulting in a refined adaptation of your construction techniques. Forget the silly box on the top. http://65.173.252.47/Six_Meter_Heliax_and_Helical_Duplexer_info/6m_duplexer _page.htm Hollow-out the center and use the outer conductor as your housing. At least it is consistent in dimensions. 2) Tuning is waay critical... a MFJ antenna analyzer just doesn't get it done. Ask the demi-gods who worked their magic on Mount Waco. There is also a little bit of black magic in the works here... you keep at it until you stumble into the right mix. Then you do your darndest to replicate that accident! Make friends with you local comm-shop so they will lend you a network analyzer. Tune the filters in place... more on that in the next bullet point... 3) The heliax notches are inherently unstable in a mechanical sense. Any small shock can eliminate your tweaking efforts. I have dropped them on end just an inch or two, and the notch moved a hundred hertz or so. Now you are on the shoulder of the notch, and make no mistake.. it is a VERY sharp notch. It is something like balancing an ocean liner on the head of a pin.. that is if you truly want peak performance. I have noticed no issues with environmental (varying temps) effects as of yet. Cover the end with a metallic cover... leakage is a killer. I have constructed several sets. Most are in the county landfill! Thinking I would need 4 filters in each leg... I am now down to 3 in each leg and very impressed with the performance. I have not solved the mechanical instability issue as of yet.. still looking for the perfect glass-piston type cap to replace the gimmick cap, and the perfect range for my pair (51.4/51.9). It seems to be a moving target.. or my techniques are just not as disciplined as needed for mass duplication.. yet. And you can forget shipping them. I agree with Skipp... partially.. I think the cost difference is more like 13dB better. The line was free, as was everything except for the roll-off components... maybe 10 bucks there... 40 bucks for good double-shield harness cable and connectors. Bottom line.. 50 bucks for a useable duplexer for 6m is a huge bargain! And you learn a lot along the way. 2yrs at it, and still learning how sloppy my work is. Skipp and I have been trading mail on this subject for about a year now... look closely at the design on a schematic level and I think you will see he is correct. Functionally there is little, if any, difference. Implementation of the design is the bear!! Good luck in your efforts.. and please share your findings. I am always looking for a better technique!! 73 Mike K5JMP www.k5jmp.us -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] Behalf Of skipp025 Sent: Wednesday, March 15, 2006 7:25 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: 6mtr duplexer steve [EMAIL PROTECTED] wrote: can anyone recommend a cheapish 6mtr duplexer, not a home-made heliax one.

In fairness, they do allow the consideration of terrain/ERP factors at locations below 3000 feet AMSL (and more stringent requirements for very high profile locations above the 3000-foot elevation). In the broadcast radio industry, we only worry about avoiding any overlap of the 60 db protected contour with another co-channel station's 40 db interference contour.
