RBN Reporting Faster Speed Than Keyer
« on: September 22, 2021, 07:09:08 AM »

Using a K44 keyer and a single lever Begali.

RBN tends to report higher sending speeds than I've set the keyer for.  So 25 wpm might be reported at 28, 28 as 30.

Today I even had 28 wpm reported as 38 eek. The reporting stations don't all report the same and most report close to my keyer speed, but still.

Looking for suggestions on keying and/or a specific setting on the K44.  Most setting adjustments on the K44 don't seem to affect sending speed since they're subtracted from spacing.

Using an FTDX 5000.

My guess is that I just need to slow down after each word...

All I can tell you is that RBN always reports exactly to what my Icoms 7300 or 7610 is set too. With the occasional station reporting 1 wpm off. But the majority is always a match for the rigs.

The RBN reports the same speed that my WKUSB, KeyLogGo, and CMOS-3 keyers all indicate.

I have the FTDX5K also and use the built in keyer and the RBN is spot on..but then I do not send 25-30 wpm..The RBN is a big help for me..Bob W5RG

Stumbled on a good idea. 

I set my semi-break in to open receive somewhere between 300-400 ms to target 336 ms, which is 7 dits, or one space between words at 25 wpm.

So I just wait till I hear receive before I send the next word !   Will see how it goes

I echo the previous comments that the RBN speed reporting has been pretty accurate on my K1EL WinKeyer.


I know the K44 has CW reading and you can adjust the inter element spacing there and I think there is a inter-element spacing on the sending side, too. Settings that and weight settings can impact the actual speed of what the RBN has to work with, which is pretty much only CQ TEST K3TN K3TN TEST at most!

 Here's a small sampling from last night while using the club callsign. My sending speed was 40 WPM which is almost exactly correct.

The “old fashioned” method of checking sending speed is to count the numbers of times PARIS is sent in one minute.

Lets just bottom line it.  The RBN is an accurate speed indicator within 1 wpm. If you keyer says something else and does not agree with the RBN, then your keyer is inaccurate. It is that simple.

My RBN speed reports were consistently 1 or 2 wpm below the rig setting.  Then I discovered I had the "dahs" set at a ratio of 3.3 rather than 3.0.  After changing that I began seeing RNB reports in line with the rig setting with only an occasional skimmer reporting 1 wpm slower.
Slightly off point but I've noticed the RBN reports the speed I have the rig selected to, up to a point at least, regardless of character spacing.  That and the aforementioned experience has me wondering if the skimmers measure signal CW speed based on dit and or dah lengths rather than true overall speed including spacing.

Pete N4ZR has written a blog entry on the Reverse Beacon Network blog that gives advice to those operating spotters and those wishing to be spotted. I gave him a few suggestions on expanding the user advice a bit, but you can see the current info here.

"Make sure the CW is good – letter formation and spacing, and 3:1 dot/dash ratio.  Any errors here may manifest themselves as copying errors. Skimsrv is pretty forgiving, but there are limits. Above all, avoid using half-spaces right before or right after your callsign."

Seems to me that among the most common sending errors are failures to provide adequate spacings during calling sequences like CQs.

My RBN spots are invariably correct and the speed observed corresponds with mine. I use a bug whose speed I estimate by matching by ear with a desktop keyer. A wpm off a couple of characters
is unimportant. In the same class as "S9 plus double digit dB or an "SWR" designation two digits to the right of the decimal.

I think the speed observations have only limited utility simply as a means of helping to ID an observation which otherwise might contain errors.
