[ADXA] A52CI FT8 decode

[patw5vy at gmail.com]

Geroge, they have been spotted on 14.092 and 14.074. They are on 14.074 now….not hearing them here.

I've not seen any spots of A52 on 10m or 20m.  What frequency have they been on?

Not to distract from Pat’s inquiry, but if anyone see’s or hears A5 on 10 meters please post here immediately. I only need A5 on two bands, 160 and 10. A snowball has a better chance of surviving in hell that I do working them on 160 this time of year simply because we have no common window. 10 is doable. The other evening when they were on 12 meters the sig was strong and a 10 meter path was very possible.

 

Anyway, please post any A5 10 meter sigs you hear (or see for you FT8 folks) on our reflector!

Dennis, W5RZ, reported difficulty with decoding A25CI on 17M FT8.  I’ve got the same issue.  In the morning (12-14Z) A52CI has been relatively strong here on long path.  The multiple streams blend into one “blob” and I have no decodes.  I’ve tried pointing east and west of the direct heading with no change.  I’ve turned AGC off, NB off, etc.  Tried Fast, Normal and Deep decode with no change.  As conditions change and the A25CI signal becomes weaker I start seeing decodes and right before propagation ends I get a decode almost every cycle.  During that time they seem to only hear EU and I haven’t been able to get their attention.  They are in and out right now…just about gone for me (1512Z).  At times they are strong enough for CW but I haven’t seen them on CW yet?

 

I have A5 on 30 and 15M CW from previous activations.  Just curious if others are seeing this destructive multipath prop?  I think FT4 would work better during the multipath….tone spacing is wider.  You lose a few db of sensitivity but I think the improved decode of FT4 would make up for it.   I’ve seen this multipath on 432 FT8 during my roving activity in VHF contests.  FT4 usually works much better.
