I notice that the two paralleled transmission line pairs understandably pick up more noise (like twin lead), more than does coax. I want to try grounding the other two pairs to see if that improves noise immunity and also whether it alters the impedance. It might also be interesting to play with a little toroidal 1:1 balun at the xmtr end of the line, to convert the single-ended xmtr output to balanced output . But in principle, I don't see and reason why both of your suggestions for the unused pairs wouldn't work just fine. 73, JIm At 08:18 AM 5/22/2007, you wrote: >Hi, Jim, > >Hmmm-wonder whether you could use the other two pair simultaneously >with the first two pairs for: > > 1. also in parallel for another 50 ohm line-say to another > adjacent (crossed) dipole, or > > 2. dc control wires for relays.

Typically, the voltage insulation is specified at 300V RMS, but with some variation among different brands. There are several versions of this stuff, including an outdoor UV-protected version, and an interesting Belden "mediatwist" 1872A flat type. Shielded types and stranded conductor types are also available. The capacitance per foot for each pair is nominally 15pF/ft, and the (maximum) DC resistance is about 8 ohms per 100 ft. Pacific Cable makes a stranded (24AWG 7/32 tinned copper) version that has 13.5 pF/ft, and a dielectric withtstanding voltage of 1500V RMS. 73, Jim W8ZR ************************* Jim Garland Santa Fe, NM www.w8zr.net ************************* ------------------------------ Message-ID: <002a01c79d65$93380bd0$18a0480c@KB6NAX> From: "Arden Allen" To: Old Tube Radios Cc: "John Sehring" Subject: Re: SWR Bridges - More Date: Wed, 23 May 2007 11:08:53 -0700 MIME-Version: 1.0 Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: 7bit > John perhaps you had too much oil in the can?

Regardless of type of oil I don't think you want a can full of dangerously hot oil. For longer than one minute test periods put the can in the bathtub and fill with water to just below the top of the can (you may have to put a brick on top of the can to keep it from floating).

The temperature differential between the resistor element and the exterior can air temperature depends on a number of coefficients, one of which is the convection of the oil, which also means the temperature of the resistor's element will vary along its length. It's pointless to split thermal units when it's known you can run a KW in the can for a minute before oil temperature reaches an unacceptable value, whatever that is. The specific heat of water being greater than oil simply means the can increases in size by many gallons when immersed in a bathtub full of water. That translates to many more minutes of run time at a KW. Calculating that time is a task too great for my overly rationed grey cells. Adding a thermometer to the can will allow you to create a power v/s temperature v/s time chart. Running the load at greater than a KW means increasing the stress on the resistor as well as shortening run time.

May have been posted here in the past. The power companies have a couple of copouts. First is line voltage tolerance which allows more variance than one would think is reasonable. The other is an increased variance due to unstable or emergency operating conditions which are supposed to rarely happen and for short periods of time. If the power company believes they have not exceeded these limits you don't have a prayer if your boatanchor melts down.

May not be possible unless the pole pot has selectable taps. But the power company would also lose money so it may be an uphill fight. I think the importance of exact line voltage is overblown if you stop to consider the incremental consequences of high or low line voltage. That's what variacs and line voltage stabilizers are for.

Dave, The USA standard for voltage has been 120/240 for many years now. There is generally a +-5% tolerance allowed, although in some remote or aging systems +-10% is allowed. The important point is there is no 220, and there hasn't been for many years. It's 120/240. ANSI C84.1 expects equipment to operate at service voltages between 95% to 105% with a utilization voltage range of 87% to 106%. 125/250 is only 4% high from the standard service voltage range. 110/220 went away around 1950 or so. 115/230 went away in the 60's. As electrical demands in the USA rise we also have a wider range of load minimum and maximums at every location. This means the voltage will change more from minimum to maximum no matter how stable they have it at the generating plants and distribution points. Since LV is nearly as harmful as HV to many devices the utilities just set it on the high end under low demand periods. 73 Tom ------------------------------ Message-ID: <010601c79ebb$b5914d20$640fa8c0@radioroom> From: "Tom Rauch" To: Old Tube Radios Cc: "John Sehring" Subject: Re: SWR Bridges - More Date: Fri, 25 May 2007 06:58:56 -0400 MIME-Version: 1.0 Content-Type: text/plain; format=flowed; charset="Windows-1252"; reply-type=original Content-Transfer-Encoding: 7bit >> The oil around the resistor gets very hot while the rest >> of >> the oil is much cooler.

Well that certainly disagrees with actual measurements I made on the cantenna for Heathkit when I was doing consulting work for them Alan. They were trying to bring stuff up to the new 1500 watt limit. I used probes in the oil. I found the oil circulated very poorly, resulting in boiling near the resistor long before the oil near the can started to heat any significant amount. Of course if the power was low enough and the time long enough the oil would heat more evenly, but the big problem was always the very poor circulation over the resistor. How did you make your measurements? 73 Tom ------------------------------ Message-ID: Date: Fri, 25 May 2007 07:57:05 -0400 From: "Chuck Grandgent" To: Old Tube Radios Subject: Re: line voltage too high ?
