ALL modern amplifiers rated at only 1000 watts DO that. The KPA1500 is rated for 1500 W and is capable of 2000 watts out. Not practical for a 120V source. Chas Subject: [Elecraft] KPA1500 110v 240v My Yaesu Quadra 1,000 watt amplifier works from either 120 VAC or 240 VAC without changing any

Re: [Elecraft] KPA1500 110v 240v

Do not fool yourself.  The Quadra is not a 1000W amp.  Try running 1000W out on  RTTY and see how long it lasts (if it will even approach that power without buenon up). The amp is a 500W amp; it is rated at 1000 W PEP; that is a BIG difference than 1000W key down.  The new Elecraft amp is a

Re: [Elecraft] Older option boards from K3 upgrade

Roger that. I missed the KXV3 in your post. I upgraded to KXV3B and gave my now spare KXV3 to a friend filling out a K3 he picked up. Friend had to pay for the shipping plus a cool one for the trouble of going to the post office. :>) Don't throw away the KXV3. Just throw away the Syn boards.

[Elecraft] KPA1500 240v (was: Another really good reason to come to the Visailia DX convention this weekend...)

That may not be true for the KPA1500. It's pretty common now, especially in higher power switchers, to include power factor correction (PFC). Instead of only charging bulk caps at AC peaks when rectifiers are forward biased, the rectified incoming line hits a boost converter which smooths out

Re: [Elecraft] Older option boards from K3 upgrade

Guy: All noted. I just hate to trash perfectly good boards when there might be someone who could use them. Not everyone will need the latest KXV3 if they're not too bothered about ten and six meters and it's possible someone could even use an old synthesizer board. They are still

Wes, I know of no A/B comparisons, but the Sherwood chart shows a significant improvement - he has rankings for the K3 with and without the new synthesizer. The lower phase noise may be apparent to you when picking a station out of a pileup or on a contest weekend with many close-in
