REPLY:
The best hardware decoder I ever used personally was the HAL ST-8000.
I have also used the DXP-38, the KAM (not the pro version) and the AEA
DSP-232.
I ran them all side by side with identical audio feed against each
other and against the software programs MMTTY and RiTTY by K6STI.
My observation was the ST-8000 and RiTTY by K6STI were tied for best
decoding under weak signal conditions, MMTTY was next best, the DXP-38
next, the KAM next and the AEA unit a very poor last.
The AEA DSP-232 was so poor it was pulled off the market very quickly
and disappeared into history. This is NOT the AEA PK-232, which I have
not tested and is far more popular than the DSP-232. How the PK-232
compares to the others I can't say, but a lot of people are still
using it today so it must be fairly good.
Hope this helps.
73, Bill W6WRT
