I cannot affirm that the cable you mention is suitable, but here is my experience.??Mark at Palstar suggested the cable made for the Ameritron 1306 Solid state amp.? It is compatible with the LA-1K.? ?The specific model for the FTDX-10 is the?Ameritron Band Data Interface Cable DB-10MY.? DX Engineering shows them on backorder until June!? After reading many helpful posts on this forum, I built my own.? Extremely easy.? Although there is some debate about it's usefulness, I find the band data cable is a better and safer option than the PTT connection/"Normal" keying mode.? The sequencing attained under the "Direct Keying Mode" is shown on p. 21 of the Palstar manual.?
If you roll your own, here's one approach:?
Note:?My LA-1k is fairly new so older manuals may be different..??The manual has the pinouts for the DB-9 "Radio Interface for Yaesu/Icom" on p.13 , bottom left hand table.? Also, you need to reference the "Linear" jack 10 pin wiring on P.13 of the FTDX-10 manual.??
I bought a multiconductor cable with the 10 pin mini-din attached because I couldn't find a connector (reasonably priced).? DX Engineering sells this and a Yaesu cable that is basically the same for more money:?
?DXE-YSU-10PMD-UN, about $25.? The DB-9 connector can be found everywhere, either solder type or terminal strip.? This is from a lead by W1SWL (Thanks Art) and is on Amazon.? There are lots of look-alikes by various company names (probably all made at the same plant) but this was as advertised and excellent quality.? Two for about $13.? I wound up using the other one on another project.??ANMBEST 2PCS DB9 Solderless Connector, RS232 D-SUB Serial to 9-Pin Port Terminal Female Adapter Connector Breakout Board with Locking Housing.??No soldering involved and you only need a small flat-blade screwdriver and a wire stripper.? The part that requires the most thought is mating the colors of the cable to the appropriate functions.? It's pretty obvious from the drawings what has to happen(a wiringto get the two ends connections ends to?It is true that this cable also enables activating the amp by keying the radio.? You must remove any connection to the PTT jack on the linear.? On the amp menu "Select Mode Option,"? you'd choose "Direct Keying."? If all is good, it gives you confirmation that the cable is detected.? In operation, when you change bands, the amp goes into standby and selects? the proper band settings thereby giving you a chance to tune up (barefoot).? When you hit the amp with a little r.f., it is set to go and you'll get the frequency readout to match the radio.? FYI, In the "Direct Mode" Palstar recommends a transceiver keying delay of approximately 11 milliseconds.? This is most important for CW.? ?The FTDX-10? "QSK Delay Time" (p. 96) can be be from 15 to 30 ms, so you are safe with any of these.? Thanks to W1SWL and all the others for help in going through this myself!
