Hi Barry, others .. Bottom line, CW was created as a "language" for humans. So what if a I would not trust any voice2text application. Just like I do not really trust the spots, either! Like yesterda

Dez, Depends what you want to do. RBN data is one source. Mirroring that with solar data takes you further. The CQ contest logs are public and you can run a next level simulation with stations that r
Big energy, wide bandwidth noise sources are not in RBN data. They will have some effect in evaluating the results with RBN + solardata + logs. For SSB contests, you can use RBN data there is; beacon
Trying to suggest ti re-using an already invented wheel: How about sending a spot for each QSO with comment QSO: or something alike that is common. Minimum effort, maximum result. 73, Jukka OH6LI ___
Hi Joe and others, Placing a stub at output connector helps a tad in case your output circuit that shows a low impedance to ground at the harmonic. That is typical for nearly all our equipment that h
Well .. with this kind of arrangement, as you are not exactly optimizing the last deciBel out of your system, experimenting is the key word. Dual stubs are out of the question as you want to have tha
Excellent show what a simple stub can do. And, when passing the receiver signal, the stub does the same effect to the transmitted signal. It attenuates the signal on the unwanted band. Excellent show
I will try and answer each question below: 2016-07-18 20:37 GMT+03:00 Rudy Bakalov via CQ-Contest < cq-contest@contesting.com>: They can be placed randomly. Even if the stub is not exactly on the her
Umm .. I did not exactly finalize the email before sending. The missing content is here: There are two things to recognize when making RF filtering; in this case with stubs: Stub tuning Placement of
Thanks Rudy .. In case you really split the hairs, there is a connection between the two; placement and length; but it is weak. In case you really want to experiment, make the stub a little long. -if
In case a person wants to experiment, he can do some experimentation. My email was written so there is no complicated measuring equipment. That is, there is no need for antenna analyzers. You can us
Nobody has answered this Joe's question as the pileup roars on thing that are easier to comment than ideas about improving the station. Excellent ! I personally get more results from protection from

Hi, I try give simplified answers ... This should answer also Rudy's question. Amplifier circuits attenuate unwanted band energy. But to a limit. A Pi filter attenuates to some level, Pi-L attenuates

A stub attenuates the pass band signal. Please check your stub attenuation. Measure the power without and with the stub; using a separate power meter. About 10% power loss is barely acceptable. 5% is

Any AFSK through a SDR TX differs fundamentally with the assumed and suggested 3kHz criteria. ARRL infirmation package http://www.arrl.org/rm-11708-faq limits the bad width to 2.8kHz. 3kHz is a diffe
