Posting FT8 Spot
|
When posting a spot by right-clicking on the call in DXKeeper the spot is posted with the transmit frequency. ?I think it would be more beneficial to post the receive frequency. ?Tuning to the transmit frequency is of little value. ?I often see spots posted using the transmit frequency then I must determine the correct receive frequency. ?For example, if the station was spotted with a frequency of 7054.7 I don't know if the receive frequency is 7054, 7053, etc. ?
?
Obviously, this will not help me but I think it would help others who see the spot.
?
Just a suggestion.

¿ªÔÆÌåÓýI have Spot Split Frequency turned on. ?In the spot note all I see is FT8. ?Anyways, I see no reason to spot the transmit frequency in FT8. ?Also, in my log the receive frequency is the same as the transmit frequency for all my FT8 contacts. ?I am using JTAlert as the interface with DXLab.Tom-KQ5S

The fact that your transmitter's frequency may be offset to ensure a higher audio frequency is irrelevant to other stations seeking to work the station whose frequency you spot.? + Spotting the exact frequency of an FT8 station is less critical than when spotting a station operating in SSB, CW, or RTTY. Almost all FT8 ops use WSJT-X or a derivative of it, and thus need only the station's callsign and band; WSJT-X will report the station's frequency when it is next decoded. ? ? ? ?73, ? ? ? ? ? ?

¿ªÔÆÌåÓýI¡¯m not looking for what frequency the station is transmitting on. ?The spots are showing the transmit frequency of the station posting the spot which doesn¡¯t help except to get me in the ball park of where I need to set the RX frequency. The issue comes into play when a station is not using the standard FT8 frequencies which is quite common with DXPeditions or some of the rarer DX stations. ?I have to manually enter the receive frequency using DXCommander in order to start decoding the station and then the transmit offset comes into play. ?If I only have the transmit frequency how do I know where to set the RX frequency to start decoding the DX station?This really isn¡¯t for me since I don¡¯t need the spot. ?It is for others viewing the spot. ? I see spots posted both ways and I much prefer when the RX frequency is posted. ?I can simply click on the spot and start decoding. ?If the transmit frequency is posted I have to guess where to set the RX frequency. It was just a suggestion and is not critical. Any ideas why the log is showing the RX frequency the same as the TX frequency? ? I use WSJTX in split mode. Tom - KQ5S

If the Entry's frequency is between those bounds, then the the?target frequency?is that lower bound.? If the??file does not specify bounds for the Entry's band and mode, or if the Entry's frequency is not between the specified bounds, the?target frequency?is the Entry's frequency rounded down to the next lowest 1 kilohertz" + If that's the case, why must you "manually enter the receive frequency using DXCommander in order to start decoding the station"? + The DX Cluster Protocol is to spot the TX frequency of a station operating in split and (optionally) include the split or RX frequency in the spot notes. + When using the direct interoperation between WSJT-X and DXLab, DXKeeper is directed to log the TX frequency only. Based on your earlier comment that you are using JTAlert, I assume that JTAlert is directing DXKeeper to log both frequencies. ? ? ? ? 73, ? ? ? ? ? ? ? Dave, AA6YQ |
