I have received two (2) actionable complaints of signal quality issues during WPX CW, which are both under review. We will investigate additional signal quality concerns. Please provide the call to b
That's an excellent step forward Bud. There's no excuse for intentional key clicks but that's exactly the place where the Japanese manufacturers have intentionally put us in 2020. The current generat
Frank, my IC-7610 has 6 and 8 millisecond options as well. Is there any disadvantage to using 8 ms? Best regards, Tad Danley K3TD That's an excellent step forward Bud. There's no excuse for intention
Hi Rob, As far as I'm aware, ARRL is completely silent when it comes to excessive bandwidth signals by participants in their contests. CQWW contest directors talk a good game, but its not clear that
Why are ARRL and the U.S. distributors not communicating with our Japanese equipment manufacturers about the problems they're causing and enabling? Good question. I first published about this problem
This is no different than having a car that can exceed the speed limit. Is it the fault of the car maker for providing car capable of excess speed? Or is it the fault of the driver. The responsibil
Hi Tad, I don't know the specific answer to your question, it depends on the details of the IC-7610 design. The October 2018 QST product review discusses the IC-7610 4 msec keying rise time and the p

Pardon a dumb question, but isn't the TXDelay normally from TR relay actuation to first RF? I know that's the case with my K3. In that case, unless you're running QSK, I don't see how that would cau

In the K3, TxDelay is simply the time from PTT out going active until RF starts being generated. PTT will negate after the generated signal goes to zero. The default is 8 mSec, which is adequate for
You are perfectly right, Pete, Insufficient PTT lead time only causes a click at the start of transmission (unless it is QSK). Most modern PA issues a warning when this happens. With the exception of
Hi all, I've been watching "The Great Rise Time Debate" - and I'm happy this is being discussed. I may have missed it, but are we all assuming that when a radio manufacturer has a "6 ms" rise time se
I am so grateful for the excellent technical information on generating key clicks, right here on this very reflector. I have now changed the CW rise time on my trusty old TS590S from the factory defa
And as I've said before, is it necessary to distinguish rise time adjustment from TX Delay settings? I think so, and wonder how many of these settable menu parameters really are TX Delay. That migh
The ARRL is listening! I actually noticed the key click situation first hand in the CQ WPX contest last weekend, and I agree it's an issue. It's worse than I ever remember it being for a long time. I
That setting is too fast. You need to replace that radio. 73, Jim K9YC _______________________________________________ CQ-Contest mailing list CQ-Contest@contesting.com http://lists.contesting.com/ma
My first mentor WB0SSB Larry told me to never insult another man's radio. Even if it's junk by my view, and even if 99 out of 100 other hams would say it's junk. The rule applies - don't talk smack
Yes, it is absolutely necessary to distinguish between rise time and TX delay. Fast rise time will always cause clicks. Too short TX delay may cause clicks due to hot switching of relays. And, as Pet
Can I make a suggestion or two for handling Key Click issues? 1) Send a friendly email to the station that was producing Key Clicks. This email should be written in a helpful, non-threatening or -ac
Who insulted? Not me. Who said junk? Not me. It is, however, a fact that radios that key that fast transmit clicks. I can't change that. When I'm doing something that affects others badly I hope that
