RE: [Repeater-Builder] New Sinclair 2M Antenna Question
Sure enough, that's what Sinclair says. The 2-Meter range Celwave PD-220-2 collinear antenna that it replaced didn't have any extra stubs or cables, and all of the other "Stationmaster" type antennas I've ever seen over the last 35 years never had anything like this. So we just folded this "stub" over and tucked it inside the mounting tube and put it up. We haven't had a chance to see how it performs yet, but if it works as well as the Celwave, it will be a great antenna. The previous Celwave antenna still looks almost brand new after nearly 14 years up in the air in the NW weather. We figured it would be time to replace it, so now we have a spare which we'll use to replace a 14 year old Scala OG-4 at another 2-Meter Repeater site, which definitely needs replacing. Thanks to all on the list who replied.

Re: [Repeater-Builder] Repeater Control
The control receiver frequency can be inside any amateur band above 222.15 MHz, and is kept secret for obvious reasons. In other words, pick a channel which you think has very little activity on it and/or isn't going to be monitored much.

Re: [Repeater-Builder] detuned duplexer cause intermod?
Tim, You are to be commended for thinking about possible interference to others; I wish all repeater owners were so conscientious! Even if the duplexer was perfectly tuned on a network analyzer, the PA may become unstable when the power is lowered below a certain point. This instability usually causes spurious emissions which definitely WILL cause interference to other stations. This is not the same as intermod. Now, when you add a detuned (or incorrectly tuned) duplexer to this scenario, it can make the PA even more unstable. The source impedance of a solid-state PA varies a lot as the drive level is changed, and the load impedance of a duplexer varies with frequency and tuning. With two instabilities operating together, it's a wonder that we can achieve a stable system. The fact that you had a desense problem suggests that your duplexer is improperly tuned, or it may simply be inadequate for your transmitter power and receive sensitivity. Desense is frequently caused by leaky jumpers between the repeater and the duplexer; these should always be fabricated from double-shielded cable and high-quality connectors without adapters. Lowering the transmitter power to cure desense doesn't always work, and sometimes the increased spurs make desense worse as power drops. You can stabilize the load impedance on the PA by adding a ferrite isolator between the PA and the duplexer input. This will greatly reduce the possibility of intermod interference to other stations. However, I don't view your detuned duplexer as "causing" intermod. It may certainly make your station more susceptible to intermod, but a ferrite isolator is the important preventive device. 73, Eric Lemmon WB6FLY "Tim S." wrote: > > Pretty sure I know the answer to this. > > But can a transmitter keying into a duplexer that's detuned cause intermod > interference? > > I have a transmitter that I turned down the power because it had desense on > it.
