[Elecraft] [KPA500] incredible hum from PA

Just got my KPA500 and KAT500. I hooked the PA up to 240v (well, my Mains are 248v), so I made sure the assembled PA has the yellow transformer tap, from the factory. When I engage the amp, there is a crazy buzz. I use a KPA500 at work, but it is on 120v and I never hear this buzz. Before I

Re: [Elecraft] [KPA500] incredible hum from PA

Kevin, Yes. had the problem. Crazy loud hum / buzz. Bad transformer I was told. All quiet on the eastern front now. If it is a bad transformer it can be fixed but you’ll have to eat the shipping charge. Joe W1GO > On Dec 19, 2016, at 9:10 PM, kevino z wrote: > >

Re: [Elecraft] [KPA500] incredible hum from PA

Joe might be right but contact Tech Support first. The transformer is held in place with a single large bolt through the center (it is a torodial transformer). If that bolt is not tightened properly the magnetic field will produce a huge vibration. Even if you did not build the amp from the

Jim, Refer to page 9 of the PX3 manual. The system integrates nicely with the PX3CBL supplied with the PX3. On 12/20/2016 12:20 AM, James Bennett wrote: I've got a KX3 and PX3 at the moment, and am considering the purchase of the KXPA100 and KXAT100. Looking at the user manual of the amp,

[Elecraft] KXPA100 --> KX3/PX3 Question

I've got a KX3 and PX3 at the moment, and am considering the purchase of the KXPA100 and KXAT100. Looking at the user manual of the amp, I see that there is an optional cable (KX3 to KXPA100 Adapter Cable) that should be used to have the units all operate as a cohesive unit. However, it appears

[Elecraft] KAT3A Question

I have a K3S/10 with a few extra filters and the DVR board installed. I’d like to purchase the KAT3A automatic antenna tuner, but want to make sure that it can be installed in this 10w version of the K3S, or does it require the 100w option? Do you feel it is a nice addition to the rig? Are

[Elecraft] KX2 Memory Operation Question

I've had 16 years of Elecraft experience with the K2 and a bit less with the K1 and KX1 - then I added a KX2 last September! Operating it has been a real blast! I suspect that my question is generic to the K3, KX3 and KX2. Operation on 60 meters pretty much requires that you program the five

Re: [Elecraft] KX2 Memory Operation Question

Dick, Look up "Channel Hopping" in the manual, that should help you with the KX2. If you plan to operate CW on 60 meters, you will have to add another set of memories that takes you to the channel center rather than to 1.5k below center as is used for USB mode. It is not available for the

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

Re: [Elecraft] KX2 Memory Operation Question

I have not done any 60M operation on my KX3, but on my K3, I have the per-band memories on 60M set up for the channels, getting all 5 them by assigning the extra to VFO-B and swapping VFOs if necessary. I have had the problem of tuning off the DX frequency while groping for the knobs on the
