Hi Rick, The last time I checked they had still not released the details of the Data Link Protocol (DLP) being used, which could be just about anything by the way, which means FCC rules make it's use illegal.
As to Matt's use of it on MARS, there too its prohibuted as it needs approval for use since its not using a standard DLP such as FS1052DLP or S5066DLP. Anyhow, to get full performance from any MIL-STD-188-110 PSK modem the radio IF BW needs to be wide enough for the symbol rate and PSK carrier being used, which in full up standard mode is a full 3Khz, This is especially critical with more channel QSB to achieve the needed error correction rate. /s/ Steve, N2CKH --- In [email protected], Rick W <[EMAIL PROTECTED]> wrote: > > Several of us have tested RFSM2400 on HF and some local hams have tested > it with me on VHF.
