Re: [Elecraft] Share a port for KPA500

I designed the S-BOX for just this type of serial port sharing. It passes all serial lines straight through from PC (normally) to Radio RS232, and taps the RXD line (Pin 2) for the KPA500, KAT500, SteppIR, etc. This works with POLL OFF as long as a logging program is polling the radio properly.

Most Hams do not have the test equipment to measure phase noise. The big issue is 49.380 MHz is an unusual frequency and probably a custom order frequency standard. The knockoff makers generally don't spend for a custom part. They take a standard TCXO and generate that frequency using a crappy PLL

I've decided it's time to get serious about saving money for a K4 purchase in the not-to-distant future. My KX-3 (S/N 62**) gets very little use, so it's time to let it get. The radio has only been used a few times outside for backyard or picnic table "dxpeditions." This is a fully loaded

I was thinking the same thing.  Several posters here said that the phase noise created was worse than the Elecraft part.  I do not understand enough about the process to understand how that works.  I keep hoping someone will buy one and try it out - and test the phase noise! Hank K4HYJ -

Larry, The KPA100UPKT totally revamps the T-R switch section on the KPA100, so the answer is yes. There is a chance that there may be a nasty spur when on 40 meters - at about 8 MHz if you do not have the upgrade. 73, Don W3FPR On 5/10/2021 4:04 PM, Larry Dodson via Elecraft wrote: I

The lack of output power on both 10 and 12 meters suggests a problem in either the lowpass filter (post-PA) or bandpass filter (pre-low power PA), which in both instances is common to those two bands. I would check relay activations on the input and output sides of both the BPF and LPF 10/12

Relating to contact bounce, I wonder what the typical length of a bounce is? We hear QRQ stations operating at 60+ wpm all the time. If Elecraft designed to smooth out such short "dots" from semi-auto key bounce, then perhaps a K4 would not allow 70+ wpm speeds to be sent either? 73,  Roy
