[Elecraft] KPA1500 Questions + RFE

"Is there a downside to using a very long FAN DWELL TIME, other than noise? I am trying to get my amp to run cooler." Your question seems to imply that you believe increased dwell will make the KPA1500 run cooler. I wonder if you have any test data that supports that assumption. My testing

[Elecraft] KPA1500 Questions + RFE

Dear Brain Trust: 1)  Is there a downside to using a very long FAN DWELL TIME, other than noise?  I am trying to get my amp to run cooler. 2)  Does anyone offer a KX3 to KPA1500 serial cable, and a K2 to KPA1500 serial cable for sale?  No, I can no longer build them myself, even though they are

Mark, The amplifier is not keyed while the KAT1500 is tuning. Similar to the KPA500 and KAT500. You do not have to put the amp in standby, it is done automatically. 73, Don W3FPR On 3/26/2018 9:34 PM, Mark E. Musick wrote: Hi Jay, Why would you need the HF AUTO ("My question is this. Is

Group good evening. I have a certain style of operation and a question about the KPA1500 I would like to ask in the group. My normal operation is the K3S into a Palstar HF Auto that tunes several antennas on my property. I have had a lot of amplifiers in the past, from solid state to tube amps.

[Elecraft] KPA1500 questions

1)  Can the KPA1500 be placed on top of the power supply for those of us without floor space? 2) What is the drive power required for full output? 3)  Can a KXPA100 be used to drive it thereby (gulp) giving us a 1500W KX2 or KX3 (or K2 with key line mod)? 4)  Will it cope with digital modes at
