I know that many costly transceivers sport these features - I have no need for transmitting - my headache is Receiving only. In my view it must have all the tools 'on board' professionally used for noise suppression, like SYNC, noise filters, noise reduction, noise blanker and so on. Probably the only remedy for me to achieve reliable decoding is a different radio or SDR. My 'trying' frequency of PC-HFDL is 8,942 - it comes through frequently at varying levels - seems that the small short 'beep' releasing the decoding proper is cut short by my noise. Space for putting it there is rather small - my lap. As for the RX I have to keep it near my window some 2m away from the antenna`s feeding socket.

My only usable antenna hence remains my 20m wire antenna sloping some 20m away from this solar roof and pointed south-east. Spending recently yet again for an Airspy Yourloop magnet loop resulted in another useless antenne - I tried it on the Airspy R2. This noise level kills the whole HF band in its vicinity. Particularly when having to 'digest' a very high permanent noise level 'thanks' to the neighbour`s solar inverters.

Thank you very much ! Apparently the Tecsun is no good for receiving and decoding PC HFDL messages.
