Re: [Elecraft] KPA1500 Operation on 6 Meters

This morning I put my DL2K dummy load right on the KPA1500 amp output (tried both ANT1 and ANT2)…I am still seeing the same SWR anomaly, where lower drive levels are giving high SWR readings on the KPA1500 display. By putting the dummy load right at the KPA1500 output, I eliminated a bunch of

Re: [Elecraft] KPA1500 Operation on 6 Meters

So, summary question for the KPA1500 amp designers: With 5 watts drive and the amp in STBY, the KPA1500 display reads the correct 1.3:1 SWR. When I switch the amp to OPER, SWR reads 2.5:1 with the same 5 watts drive. All hardware/cabling outside the KPA1500 remains the same for each case.

Re: [Elecraft] Best Audio Interfaces 2020?

Thanks Wes. Yes, my older iMac has an audio input and a surprisingly good soundcard. The reason I need the interface now is that my newer MacBook Pro doesn’t have a mic jack, so an external USB device is the only practical option. Ideally the USB interface would be USB-C, but I don’t think

Re: [Elecraft] Spurs on 6 meters on FT8

I have an older K3 ( under 3000) so I do not have the newer KPA3A. Several yeas ago I had to replace at least one of the driver transistors. At that time I also changed some transformers either on the driver or final board. I do not remember without looking but the nature of the wire change was

Gary, There are a good number of extremely loaded “pre-owned” K3 and K3S units available these days. I’ve seen a bare bones K3 for a little as $1300 USD and I sold my completely loaded contesting K3s for barely over $2000 so a GREAT deal can be had. It would be worth the risk of an eBay

Re: [Elecraft] K3s discontinued?

I don't understand the "shock" at the K4 pricing. If you "load-up" a K3S with all the options you'd have to buy that are included in the K4, AND add a P3, with VGA & transmit monitor, I think you'll find the K4 is a BARGAIN! 73, Charlie k3ICH -Original Message- From:

Re: [Elecraft] K3s discontinued?

This is probably true in term of value. I am also on the opinion that having an option between the K2 and the K4 makes sense, even if it doesn’t have all the bells and whistles. Like having a kx2 and kx3. JC/W6IPA. > On Jun 15, 2020, at 8:32 PM, Charlie T wrote: > > I don't understand the
