Yes, I know this is an antenna newsgroup but the people who read this
traffic may be able to help me. I have always used the PK-232 for RTTY and Packet and never really messed with the putting it into the keyboard mode for CW transmission. For grins I decided to try this morning and ran into all kinds of problems and could use some help. First the TS-570 was designed for the operator to use his personal keyer with the 570's internal keyer. The internal keyer is activated by plugging in a Stereo Phone plug. If you want to use and external keyer (like a PK-232), you have to use a Mono (tip and Sleeve) Phone plug. The PK-232 has a Plus (+) and Minus (-) RCA jacks on the rear. I cannot find anything at Radio Shack that goes from two RCA's to one Mono Phone. Really weird setup. I found a RCA to Mono Phone plug and and it causes the 570 to send a stream of dits when plugged into the (+) output on the PK-232. If I plug the same cable into the (-) RCA jack on the PK-232, it causes the 570 to send a stream of dah's. Looks like I may have to rig up some special non standard cable taking the center of the (+) RCA plug to the Tip of the Phone Plug and the center of the other (-) RCA jack to the sleeve of the Phone Plug and let the grounds float. Do I had to dummy down the TS-570 buy turning some menu functions off? Anybody out their CW keying a TS-570 with a PK-232? Dick, AA5VU ps: Just made up the cable mentioned above and when I turn on the power, the TS-570 starts sending a constant string of dit to the side tone oscillator... like someone duck taped a Bencher. I must be doing something pretty dumb. Page 3-6 Section 3.3.5 of the PK-232 manual is really confusing with a totally useless Direct CW Keying Cable diagram. Again, anybody been able to key the TS-570D(G) using a PK-232. I need help. Dick, AA5VU |
