I am not saying it isn't, but I have never heard 'Resistor Tolerance' related to standard deviations. I am sure it's it used by the manufacturer to control their manufacturing process,

 Darryl:, Let 'x' = the value of a resistor in parallel with a 51.2Ohm resistor to yield 50 ohms equivalent resistance. 50 = 51.2 x / (51.2 + x) (Product overthe sum for 2 resistors in

I could be wrong, but I don't think a 1% resistor necessarily means the value is within +/- 1%. I think there are some statistics involved which might say, for example, that the

Darryl, I would definitely mount it on a larger heatsink. Do you have a heatsink from an old computer? That is one no-cost source of heatsinks. If you do not have one, you may want

If you can, try SSB on 7.285 tonight...7:30 and 8:30 CDT. This Monday night SSB net has been trying to get off the ground. I plan to try 8:30 for sure and maybe 7:30 if we are finished with

Thanks for all the comments, meter is a old Fluke 79 Series II, good meter, can calibrate the lead resistance out, but the meter itself is not guaranteed calibrated. I was just pleased to get a decent

Darryl, That's only a half an Ohm tolerance, 50 x .01 = 0.5 plus/minus. Your meter may not be accurate enough to measure that. The value you measured might be the resistance of the test

Yes but, as you can see from his photo, he paid for a 1% resistor !! For $11 (+ shipping), I would be calling the vendor. OR MAYBE, the error is in the device he is using to measure

Hi Darryl, Don't even bother about a parallel resistor. Use it as-is. It's barely 2 percent off. How accurate is you DMM? How do you know? Our solid state radios will work happily into 75 ohm

Hi Darryl Should be 2K2, this equates to 50.0355 Ohms total effective resistance. Not sure on power as the 51.2 is only about 3% of the 2K2. Anyway why worry about the error? the error is less that 3%

This is my new low cost dummy load, made with a Caddock thick film non-inductive resistor. This one is 50 ohms at 1%, and rated at 100 watts, and costs about $11.00 from Mouser or Digikey. I realize

I hope the lightning stayed away from your QTH last night, at least long enough to participate in the SSS. This is Dayton week and a lot of you will be busy packing the next couple of days. Before

I'll see if I can persuade my antenna on to 17m and then I'll report back (I'll listen out as well). have a blessed day Wayne - KC0PMH -- http://www.qsl.net/kc0pmh/ Under construction but please

Doc, Another headset choice is the Yamaha CM500. I find it more comfortable than the Heil headset and has a very sensitive electret microphone. It can be found at Pro Audio sources

Doc, I am having trouble understanding your situation. Pull the Heil Pro Set mic and headphone jacks out of whatever adapter they are now plugged into and you should see that they are

I wish I could use my Heil Pro Set with my LNR LD-5, but the jacks are 1/8" and Heil does not make an adapter for that. What do you all recommend for a high quality headset that I could use? _ _ ...

You may find better luck with the 74HC family since it is rated to work from 2 to 6 volts. One thing to keep in mind is noise immunity. As the supply voltage decreases, the margin
