CW PTT
|
Hi folks I have a remote station
operation using an ICOM 756 Pro 3, Airspy HF+ Discovery SDR and a
Palstar LA-1K amp. I use an RF switch relay to switch between the SDR
and the Amplifier. For Software I use Ham Radio Deluxe for CAT to the
ICOM radio and N3FJP ACL for logging and keyboard CW. Computer is Windows 10 64 bit. When I try to send CW while operating contests or casual QSO's I always get the first character of the letter cut off when I start sending. When I use the ACL keyboard to send CW, the first
character i.e. a dit or dah is cut off. If I use a keyer directly onsite with a separate PTT line to the radio no problem. I suspect the semi-breaking keying is too slow for the relays to close, losing the first dit or dash. I use a physical
RS232 port to key the PTT on the radio from a RS232 COM port on the back of the radio but I can find no way to
configure that port in the CW settings of ACL. I can configure a direct PTT com line from the ACL Phone
settings. What am I missing - is there any way to key the RS232 com port PTT line immediately when I hit send from the keyboard? Thanks for the help. Paul NO0T

Hi Paul,
Thanks for your e-mail. I am by no means a hardware guy, so you will definitely need more help from others on this one than I can provide. If you are using internally generated CW (not Winkeyer), there is an option to key your amp via RTS or DTR prior to the CW keydown if that helps.
Good luck with your project! 73, Scott

Hi Scott - I tried the CW PTT for Amps check box but I can't find where it defines which com port I am keying the PTT. After I check the box nothing happens. In the ACL Phone setup we configure the com port for PTT as shown. I am looking for the same set up for CW. Thanks and 73 - Paul NO0T !

Hi Paul,
Thanks for your follow up. Choose the com port you have your CW interface connected to, from the upper left list of the graphic you sent, under the Com Port heading.
The amp keying is opposite the CW keying, so since you have DTR keying selected, your amp will be keyed from the RTS line (assuming you have all that configured on the hardware side).

Thanks for getting back to me so quick Scott. I'm not quite sure how to wire up the hardware but it sounds like there would be two separate cables coming from the same RS232 port - one for CW keying and one for the PTT. I would appreciate if there is someone on the blog who has done this could maybe contact me. Thanks 73 Paul NO0T
