Hi all. I to have used the dow stuff for years. It is 4 Compound I believe it is the same as the goop that andrews supply with their hardline connectors. Just about all the outdoor connectors that I have used over the past 30 years has had it in the connecting faces as well as inside the body. I have used it in the electrical joints on my boat trailer and on my 4 wheel motor bike(this is where faults apear in time). Cheers from down under. Ps I am making a portable repeater on 460mhz 10/15 watts and would like not to use a diplexer can you advise the solution. Maybe a tx groundplane with a solid disk and have the rx ant hanging directly below ie 180 degree to each other. The ch spacing is 500khz. I would use a foil or at least a double sheilded cable for each feed.

[Repeater-Builder] Re: SEA ESP1000
You are on the right track. 20 watts is not really enough power. Most of the 220 acsb systems I saw were poorly applied and built from plans made by people who appear to have never been in the field. When you get into a new technology, there is always strange issues to be dealt with. I had some Intek/Securicor technical files, which indicated to me they were not properly dealing with those issues. You can only hide so long behind a patch job. Something about customer support also comes into play. cheers, skipp ps: There is still a system or two in operation up here in Nor-Cal. How many people are on it is another question... Jim B.

Re: [Repeater-Builder] Caution on Bomar Crystals
Expensive: Mototola Mitrek recrystal and tempco at ICM: $50.00/element. Bomar is $35.00. West is appx. $32.00. There was a debate regarding West Crystal's alleged "temperature compensation" a week or two ago on here. Check the archives - I forget the conclusion, if any. Bob NO6B The figures above that Steve-WA6ZFT gave are incorrect. Bomar charges $25 to re-crystal and TC "your" element, not $35 YMMV, but in a direct conversation with a person claiming to be an engineer at West, I wasn't convinced that they actually TC the crystal in the element/ICOM. Only after a VERY lengthy discussion and proving that I knew the difference between TC'ing and "netting" did he admit to only changing the parallel capacitor to achieve "on frequency" with the trimmer centered. His thought was this measure was "compensating" the element. After that, I was uncertain that West Crystal actually knew what proper ICOM or Channel Element TC'ing really was. I was also not convinced that they check the modulation linearity or characteristics when redoing a FM TX element, something that I know ICM and Bomar does. Does West Crystal do this, I don't know, and I'm not going to call yet again to find out. I was very discouraged from talking to them the first time, as I think they were trying to buffalo me into thinking I was getting something I'm convinced they weren't giving. In crystals and crystal companies, you get what you pay for Again, YMMV, and likely will. Kevin Yahoo!

[Repeater-Builder]
Hello all -I am trying to help a friend of mine get a Mastr II mobile fired up on 2 meters. We are having trouble getting any thing out of the transmitter. Receiver seems to be working OK although I'm sure it needs tweaking a bit. We cut off the control head and built a small circuit similar to the NHRC Vol Sq pot assy. and that is all working fine. I was told that you would get 10 volts to a pin on the transmit icon when you went to the transmit mode. We have one pin ( I will call maybe pin 6 for the icon that has 10 volts full time - the one next to it ( Pin 5 ) has about 5 volts full time. I see nothing else changing on any pins whether in transmit or receive. What on earth are we missing here. This is a first for either one of us. The receive does drop when we tell it to transmit soI feel confident we are keying it correctly. I know the TX is out of tune but how or where to begin when it seems there is no output anywhere at any level. Also have a second transmitter and same problem so I feel there is something we are obviously missing. Dave / N0ATH Yahoo!

Dave, It would help us out a lot if you can specify the complete model number of the radio, and also the numbers ink-stamped on the exciter and oscillator-multiplier boards.

Re: [Repeater-Builder] Repeater Desense
Yes. Many repeater receivers are simply not well enough shielded to keep the TX from leaking into the RX box. Even some commercial repeaters will suffer desense if 100% shielded feedline is not used. I have seen serious desense occur when a dual-band (2m/440) antenna is used on a repeater, due to the uneven gain versus frequency response of many such antennas. Invariably, the desense went away when a good broadband antenna was used. 73, Eric Lemmon WB6FLY DCFluX wrote: Has anyone had desense due to the fact that the repeater's antenna is too close to the repeater itself?

[Repeater-Builder] Daniels repeaters
I'd like to compare notes with anyone who might have a Daniels repeater, specifically the UT-2, UR-2, VT-2, or VR-2 I got one on fleabay recently, and boy it looks nice. This is the first time I've seen a receiver that uses a two-stage helical filter on the first IF local oscillator! Makes sense though. They use a four stage unit on the RX input. I'm working toward ordering the crystals. They spent a lot of effort compensating them from -40C to 60C and I don't want to negate that by specifying the wrong thing. They give the crystal formula, but so far, I haven't found any more information in the manuals, than the crystal formulas. They don't mention loading capacitance, temperature information, what sort of cut Beautiful gear, and the one I have is in beautiful condition. Looks like it was sitting in a clean room for the last 20 years. Yahoo!

I stand corrected. I just confirmed this by calling Bomar. Some TCXO's will be more, but most are $25.00 including the crystal.

The antenna was positioned almost exactly as yours is, perhaps a couple of feet higher. The repeater was 'homebrew' (sort of) but I had been extremely careful with shielding and filtering in construction of the repeater itself - rx, tx, and controller in separate compartments, each fully shielded with filters on all leads in and out of each compartment. All interconnecting cables outside the box were mil spec double silver shield RG-214 and feedline was RG-214 later changed to LDF4-50A. I could not run more than 20 watts without desense. I never did figure out how the desense was occurring. Once the antenna was relocated (50 feet vertical and 20 feet horizontal) I could run 100+ watts with no problem.

So, I decided that whenever he was going to practice, I wasn't going to get any sleep anyway, so I might as well chat on the local repeater. With the antenna in the right place, I could DC bias his amp to off, which didn't bother me any. He eventually would give up, apparently figuring that he had overheated the amp, or broken it somehow. When he gave up, then I could go to sleep, so I would stop talking on the repeater, and get some rest. Yahoo!

RE: [Repeater-Builder] Caution on Bomar Crystals
This brings up an interesting memory, I worked at a nationwide paging company and was moved back into repair manager after the new manager guy was fired. (He got caughtlistening in on a private conversation with a Telco buttset between a tech and the President of the company)I started the shop and then they hired anew guy to release me for more important assignment. After a couple months the reliability of the repaired pagers wentfrom 2to 3 %to a whopping 97%dead when they were returned to the field! The guy was a real winner! After I got settled back in my old office about 35 miles closer to my house I started talking to the techs and following what this new guy had them doing. Under his instruction they were to monitor the analog audio out of the pager with an oscilloscope and "tune" the 1st oscillator until the scope triggered! I asked how and where do they know where to set the trigger to get the frequency correct? They all said they did not know, it's just way the shop manager said it had to be done! I found the pagers were way off frequency.What I did is come up with a RF sniffer and the calculations of each model of pager's injection frequency so they could read the injection frequency out on the service monitor. I personally don't like the injection method of setting the frequency but it was the most simple way for the techs we had at the time. This one change took the failure rate from 97% to 2 to 3% in two weeks, a complete reversal! My job was done.

Re: [Repeater-Builder] Repeater Desense
Bob, The most recent instance was with a Cushcraft ARX-270 2m/440 antenna. I watched this antenna being assembled, and I can state that there was no corrosion, maladjustment, or looseness involved. We used that antenna briefly for a 2m repeater simply because it was already in place, and we had a special event to cover. A Motorola RKR-1225 repeater was hooked to it using LDF2-50 Heliax feedline. When the Cushcraft antenna wouldn't work without major desense, I swapped it for a Sinclair SRL-222 dipole, which worked perfectly. 73, Eric Lemmon WB6FLY Bob Dengler wrote: At 5/12/2005 12:37 PM, you wrote: Yes.

At 10:57 AM 5/12/05, you wrote: Has anyone had desence due to the fact that the repeaters antenna is too close to the repeater its self? Like 12 feet of vertical seperation and 2 feet horizontal? Absolutely - if the shielding is missing, or the designer didn't put enough on to start with, any high level signal can cause desense. Sometimes the repeater can desense itself. Look at the formulas for a UHF Master-Pro sometime, and picture it listening to 440.600 and talking on 445.600... At that frequency pair a TX harmonic nukes the high IF. Mike WA6ILQ Yahoo!

[Repeater-Builder] Re: Caution on Bomar Crystals
This past December I ordered 7 crystals from Bomar Crystal for $70.00 + $10 shipping. When I received the crystals, one pair was reversed Tx and Rx. When I called them on it, They said that it was what I had ordered, and so graciously offored to re cut them for $10 each NO MINIMUM (WOW WEE)so I paid it. One of the other crystals for a transmitter was Tango Uniform (DOA).

[Repeater-Builder] Re: I need to take 5 volts to 8 volts, and one have a schematic
Well Mathew, being a general, and with all the nice gear on the wall in your shack photo on QRZ, you should learn about Optos. If you can wire up a LED with out letting the smoke out, AND use a NPN transister for a DC switch then you might be able to use an OPTO to control an 8Volt device from a 5 Volt device and vic versa. The quality of a repeater depends directly on the quality of equipment, and the knowledge of the builder, not on the amount of money spent.

Re: [Repeater-Builder] Re: Caution on Bomar Crystals
I beleive ICM will send you an order confirmation via snail mail, but it has been such a long time since I ordered from them I'm not sure if they still do.

[Repeater-Builder] Sinclair dipole harness waterproofing
Probably a dumb question, but I just obtained a new Sinclair SRL235-2 antenna. The factory 'Y' junctions in the harness are enclosed in plastic clam shells which were apparently filled with some type of goo and then clamped onto the cable. The goo around the edges is still very... well, gooey... it's apparently not a material that hardens after being applied. My question is, do I need to waterproof these joints or are they weatherproof as they are? Since they are factory junctions, seems like Sinclair would have waterproofed them if they needed it???... but they don't look like something that is all that waterproof to me. They also look like a bit of a challenge if they do need additional waterproofing. That end where two coax cables come out of the clam shell would be fun trying to seal and tape. Any info / advice?

Re: [Repeater-Builder] Re: DB-228 Mounting
If I remember correctly, a 228 is two 224s on a double-length mast. If that is the case, then I suspect that a 224 clamp kit will not be enough for twice the weight and twice the wind loading. I'd plan on fabricating something equivalent to double the 224 kit, then have it galvanized at the local plating shop.

Re: [Repeater-Builder] Re: Caution on Bomar Crystals
At one time I had them make crystals for a number of Motorola radio's HT that was in use in Florida. This was in June or July. Had the Motorola factory have to tune them a number of time the first 90 day. Then they stay ok till we had them in Gatlinburg, Tn for a late December show. Most of the radio's were so far off freg we could not use them. Last time I used ICM. Also them main reason for the fax is no one can not say what was not ordered or freg .

Re: [Repeater-Builder] Re: DB-228 Mounting
Hi Lloyd, For the two meter db products antennas, I use their db5001 side mounting kit. While we are on the subject, I have a set of db products antennas for sale which were custom made for a split site repeater. The set consists of a db222(dual dipoles) receive antenna and a db215(dual dipoles, dual 3 element yagis) transmit antenna. The db 215 has a keyhole pattern and the db222 should be sited in the middle of the pattern. If anyone is interested let me know. I can't ship them and I am located in Eastern, Ohio about 3 hours from Dayton. Mike N8RQU --- Lloyd M. Mitchell [EMAIL PROTECTED] wrote: I have a DB228E that I want to mount on a 300ft tower.

Re: [Repeater-Builder] Repeater Desense
I had an arx270 to slowly burn the cap out @ the feed point of the antenna. They will not handle 100 watts @ feed point on continuous duty. I contacted Cushcraft and they sent me a new cap at no charge. I use it home now, no repeater use.

I watched this antenna being assembled, and I can state that there was no corrosion, maladjustment, or looseness involved. We used that antenna briefly for a 2m repeater simply because it was already in place, and we had a special event to cover. A Motorola RKR-1225 repeater was hooked to it using LDF2-50 Heliax feedline. When the Cushcraft antenna wouldn't work without major desense, I swapped it for a Sinclair SRL-222 dipole, which worked perfectly. 73, Eric Lemmon WB6FLY Bob Dengler wrote: At 5/12/2005 12:37 PM, you wrote: Yes. Many repeater receivers are simply not well enough shielded to keep the TX from leaking into the RX box. Even some commercial repeaters will suffer desense if 100% shielded feedline is not used. I have seen serious desense occur when a dual-band (2m/440) antenna is used on a repeater, due to the uneven gain versus frequency response of many such antennas. A narrowband antenna by itself will not generate desense. Your problem was probably due to corrosion, dielectric breakdown, or some other cause related to poor construction/materials in the amateur grade antenna. I would like to know what model antenna this was though, since I have yet to see any desense problems with my Comet antennas. Bob NO6B Yahoo! Groups Links Yahoo! Groups Links Yahoo!
