I am looking for an interface cable for the Elecraft K4 to LA1K? Is there one available or did you have to make it?

开云体育

I made mine for my Yaesu FTDX101MP to the LA1K.

Ordered a cable from Amazon and a modular connector from Amazon.. (hope this picture takes…)

As you can see the Jienk cable has gold plated connectors which you fit into the ANBEST DB15 solder less serial 15 pin port.

Is your connection 15 pin to 9 pin on your Elecraft?

This cable fabrication was rather easy with these two parts.

As a result, when my Yeasu changes bands the LA-1K also immediately changes bands as well PRIOR to the introduction

Of any carrier or transmission.

Winford makes nice breakout boards.?

Remember NOT to connect anything to the PTT jack on the LA-1K if you use the keying pins in the DB9 jack. ?It's one or the other but not both.

Also, if you're an avid CW operator, the LA-1K can be a full break-in amp with the ?addition of an electronic T/R switch such as the DXConnections QSK2500. ?The owner (K3HZP) hand-makes every unit and gives excellent support, especially in how to cable everything up.

QSK keying is then done in the "DIRECT" mode rather than the "NORMAL" mode.

I plan on doing something similar with my FTDX10 to the LA-1K. The FTDX10 uses a 10-pin mini din, so I ordered a Yaesu SCU-18 cable to connect to a 9-pin solder-less terminal connector. I just have to make sure I get the correct wire to the correct pin. I'm using the chart in the LA-1K manual as a guide.

According to the FTDX10 manual, you want an SCU-28 cable for connection to the LA-1K (not SCU-18).

Snip off the other end, and wire it to a break-out board:

(spring terminals and thumb screws)

It worked perfectly from my 101MP to the LA-1K. ?I used the two parts which I sourced from AMAZON.
Hope this helps..??

Pardon the typo... Yes, it's SCU-28 cable for sure! Thank you.

Thanks for the that info. Very helpful. Waiting on my parts to arrive and get the LA-1K on the air.
