General discussion forum / Re: WiFi - How I finally have reliable remote CW keying with my RRC-1258 pair
« Last post by G0KPE on 2023-12-28, 15:24:36 »Hi Mike,
Thanks for responding. Although my ping return time is <10ms here on my home network where I have been experimenting, I have the TX delay set all the way to max (250ms) and use the local sidetone from my RRC-1258 control unit. I have the LF delay set to 450ms so that I do not hear the radio's sidetone on the AF streaming link, which BTW is perfect - no dropouts. I have made many adjustments to the TX delay value in my experimenting.
It is easy to set up a test to demonstrate the CW dropouts/gaps when using the internal WiFi board option in an RRC-1258 MKII, as long as you are close enough to be able to monitor your radio's transmissions off-air on a separate receiver. I have a portable receiver to listen to, plus I have a waterfall display to observe my remotely keyed transmissions. I have both the Control and the Radio RRC1258 MKIIs connected to the same home router. The radio one is connected on Ethernet, the Control one is WiFi-connected.
With a paddle key attached to the RRC-1258 MKII, hold down the dit or the dah paddle. Listen to the off-air transmissions. Within 15 seconds of key-down you will hear the first gap dropout, with others following.
One of my tests was to add a switch to Input 0 (set as KEYER), to generate what should be a constant key-down carrier. This is not the case though. There are gaps in the transmissions. Listening to the Control RRC sidetone, there are audible glitches every second. I have observed that the remote radio transmission gaps, when they occur, are synced with these audible sidetone glitches. When using Ethernet or an external WiFi device, the audible sidetone glitches remain but there are no remote transmission gaps, just the expected constant carrier. It is as if the Control RRC-1258 with the internal WiFi board fitted, is sometimes missing the paddle key input states at the exact instant of those 1-second glitches. Is that possible Mike?
As I mentioned in my original post, moving away from the internal WiFi and instead using an external WiFi unit has removed these remote transmission glitches/gaps and my CW is exactly as keyed (currently with that 250ms delay).
