In a QSO with Gennadi / ES3RF , who is located directly in Tallin, i let the audio recording run and coud use this file to reproduce
the main elements for the screenshot. You can see the coarse steps of a MS QSO. Gennadi's last
trasnmission can be seen as the vertical red dotted line right above the green audio peak. You get an impression, how strong his signal
was, because the black area after the redish line was the ALC tuning up the sensitivity slowly after this event. The green / blue dotted
area is just standard noise when receiving nearly nothing (except noise).
Gennadi sent a row of 73s. They occur in the last line of the QSO in the middle of the screenshot. In the same line are also some more interestic
data fields as "dB", which means, that Gennadi's signal was 8dB above noise level during this transmission. This is typical for MS connections.
Most time i let the radio run with closed Squelch on 144,370MHz. If a meteor scatter signal can be heard, i can directly switch to "operating
mode"...
While the BCC-MS-Contest was taking place (every year @ the high season of the Geminides), i could learn a lot of things.
I ha my personal training on interpreting the WSJT parameters and also in answering CQ and more. This sounds as some trivial
things, but in fact it is not. I did not have much QSOs at all...
I was wondering, why nobody answered me in the
Chat of ON4KST.
After observing the ado i saw, that someone wrote about the contest rules: "only random QSOs allowed - no QSOs via Chat".
Next i was fooling myself by turning the antenna in the direction of the calling station - no answer at all, but also no more to hear...
If you study this very mode, it will get clear, what the failure was.
Problem 1: The antenna was turned away from a reflection point that was surely working
Problem 2: Generally CQ calls will be done on a certain frequency - mainly on 144,300MHz-, but the caller will listen and do the QSO on a different frequency. This can be seen on CQ texts like „CQ 68.." or „CQ 368", who directly show the listening QRG. Another way of giving this information is to send CQ "AA" = TX-QRG + 27KHz, CQ "BB" = TX-QRG + 28KHz, CQ "CC" = TX-QRG + 29KHz, etc...
