You will need the CSF100SADJ software to make the power adjustment.

[Repeater-Builder] RE: Stationmaster Ant....to use or not????
Hello again to the group, I'd like to thank all those who responded to my concern about using a Stationmaster Antenna to replace the G6-440 currently in place. It looks like the Stationmaster will be a suitable choice to replace the G6. (Which I felt would be the case ;-) To address some of the replies, in no particular order,... I didn't mean to imply the Hustler is a poor choice for a repeater antenna,...It's just I know several people who have a bad attitude regarding those ants., and bashing them would not have lent any practical information to helping make our decision. The G6 currently in use is performing quite well. The possibility of using or changing to a DB-404,408, does not exist in this case for a number of reasons. Would definitely be a worthy replacement for the project,...just not feasible at this time... As far as the age of the antenna, the radome is in surprisingly good shape for its age,...almost looks as if it's been in storage(hanging in someones garage) for the last 15-20 years. I know this doesn't mean much with respect to the innards...We had planned to disassemble the antenna and inspect (and repair if necessary) the joints between the elements, as well as re-weather-proofing the outside seals at the tip and mounting/decoupling sleeve at the base. With respect to an isolator in the line,...ABSOLUTELY,...wouldn't leave home without it...Especially on this site which will be shared with several other UHF VHF repeaters. Thanks again to all, for the information to help make our decision easier... Carl KA9GPX

Re: [Repeater-Builder] WiFi interference to UHF?
It is usually the data radiating from the 10/100 cable. Try ferrite beads on both ends or going with STP (Shielded Twisted Pair) cable.

Re: [Repeater-Builder] WiFi interference to UHF?
Ken, I built a UHF repeater in Orlando, FL which had this problem after I sold it to a subsequent owner. The site was an 18-story office building roof where I had secured a rent-free lease, and we were the roof's lone RF occupant. My group built and installed a weatherproof cabinet and AC power. The repeater's subsequent owner was approached by a Part 15 wireless company with an offer of a free broadband connection at the repeater in exchange for housing a UPS and other equipment in the cabinet. Needless to say, li'l ol' 442.250 acquired IRLP and APRS super-powers, but the kind of interference you describe was an issue. From a legal standpoint, we were a licensed operation, so under Part 15, he bore sole responsibility for resolving the interference. From the landlord's perspective, he was paying rent and we were not. Nuff said? Anyway, there were apparently off-the-shelf filters available for the wireless nodes which completely solved the problem on the repeater input. But they apparently compromised wireless coverage, (or the wifi guy thought they did, in a sort of reverse-placebo effect,) so he kept taking them off. Eventually the problem was resolved permanently by four hurricanes in one season, working in concert with his wind load profile. He could no longer justify constant antenna replacements. So, long story short, there apparently are high-pass or bandpass filters out there for wifi radios. You'll want to do some research on their insertion loss. The experience in Orlando also suggests the issue is related to the radios themselves, not the CAT5, because we had it routed right through the repeater cabinet. I don't know if the ethernet cable was shielded at that site or not, however, because I'd already left town. Hope that helps! 73, Paul, AE4KR - Original Message - From: Ken Arck To: Repeater-Builder@yahoogroups.com Sent: Friday, February 22, 2008 12:57 PM Subject: [Repeater-Builder] WiFi interference to UHF?

Re: [Repeater-Builder] WiFi interference to UHF?
Ken, I've had that problem on several systems. Running shielded CAT5 took care of most of the noise. I still can detect the noise on a very weak carrier received by the UHF repeaters but it's not bad enough to degrade service. The interfering signals aren't present all the time. They seem to slowly move across the repeater's input frequency. I don't believe there is any UHF signal being radiated by the WiFi antenna. Installing a band pass filter between the radio and antenna made no difference in the noise.

Re: [Repeater-Builder] WiFi interference to UHF?
when I have run Cat 5e I have run it in conduit ( out side conduit , it screws together) and never had a problem .. but then again there was no UHF ant there eather a little more $$ but it keepts at cat5e safe from the sun/rain/snow/hail ..

[Repeater-Builder] RLC- 2a Link Controller problem
I have a Link Controller RLC 2a V 4.28 running two independent repeaters on port 1 and port 3. Port 1 can access several micros to turn on and off several functions not related to port 3. Port 3 can access only one micro to change its courtesy tone. The problem is when either port is sent a DTMF command the other port momentarily keys its transmitter just after the command is entered. This is not a big problem but if anyone has run to this and has a solution I would appreciate an answer as to where to start.

Re: [Repeater-Builder] WiFi interference to UHF?
Hi Ken ... I run different brand names of wireless equipment and with that in mind some of the different AP use different IF freqs . Here is a way to help out with the problem. Make sure the wireless is a min of 20 feet away from the repeater antenna, make sure the AP is mounted in a steel in closure and grounded properly ... and use shielded cat cable. That should take care of it ...

RE: [Repeater-Builder] WiFi interference to UHF?
Very common in both VHF and UHF with certain WiFi equipment. Antenna separation will be your friend. If the problem is bad enough there are relatively inexpensive filters.
