Re: [Elecraft] Checking VFO accuracy using WWV

It is human nature to be disappointed if we don't get the nominal figure, but only the lower limit even if still within spec. We wouldn't complain if we got a few Watts more than the 100 Watts, and of course 100 Watts sounds like a lot more than 89 Watts just as $100 does to $89. 73 from

Re: [Elecraft] Checking VFO accuracy using WWV

For the KXPA100, the tolerance is specified. See page 30 of the manual. "Power Output: Max.100 watts at 13.8 V, 1.8 to 29.7 MHz and 80 watts 50-54 MHz PEP CW/SSB/DATA, ± 1 dB“ wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Dec 18, 2016, at 9:22 PM, Jim

By your "logic" a few weeks ago when my 100 W K3S started putting out zero watts it was still in spec, since there isn't any, Right? And if you want to open another can of worms let's talk about "typical" TX IMD. On 12/18/2016 10:22 PM, Jim Brown wrote: On Sun,12/18/2016 2:04 PM, Wes Stewart

Re: [Elecraft] Checking VFO accuracy using WWV

I totally disagree. If the manufacturer specifies that the transmitter puts out 100W, and indeed uses that as a part of the part number on the order sheet, then it's not unreasonable for the customer to expect 100 W out. That's like buying a Lamborghini Huracan LP 610-4 and discovering that

One part of Amateur Radio is transmitting and receiving. Another part of Amateur Radio is design and construction of equipment. Yet another is delving into the concepts of doing things with available equipment/methods. Traffic handling was once a big activity ... think "American Radio RELAY

Re: [Elecraft] Checking VFO accuracy using WWV

Expectations may be too high. All these WWV methods assume there is no Doppler shift present on the WWV signal. Other things to consider: TCXO drift, synthesizer limitations and new synthesizer quirks. During disturbed times, Doppler could be 1 Hz or more. Unfortunately, the Doppler

Re: [Elecraft] Checking VFO accuracy using WWV

The R.L. Drake Company referred to the zeroing or beating indicators as "canary chirps," the goal being to slow the "chirping" until there was a steady tone indicating you were then dead-on. I still find that the most descriptive way to tell someone how to identify the pulsing when doing the
