[wsjt-devel] Q65B signal below decode - real or imagined ?

[Nic S. <nic...@ta...>]

Hi Nic G3YEG here, qrp 432Mhz EME station.

With my very small system I have now managed to successfully decode 37 different stations and estimate that without faraday intervention I have a high probability of decoding any EME station running more than 30Kw ERP.

Over the years, like many other stations, I often see valid DT values before a full decode.

What I have also noted is that quite often I will see repeated similar “odd” but not correct DT values when on the correct tx period from stations. 

My question is this - is this a real observation of the stations signal due to the nature of the Q65B signal or is it my imagination?

My set up is not that sophisticated (9700 with sp70 lna , short cables and 9 ele in loft space) but i use the very latest wsjt, new laptop with i7 and 32gb memory. I always re run files using single decode together with  a sliding window technique moving the qrg to find signals with ftol set at 50hz

Thanks in anticipation of ideas / explanations.
