I'm getting a bunch of strange packets sent to pskreporter that (I
think) are coming from wsjt implementations. For example:
AD BC CB DA 00 00 00 01 00 00 00 00 00 00 00 04 4D 53 48 56 00 00 00
01 00 00 00 04 31 2E 34 32
I think that this is wsjt because of the adbccbda header (which google
helpfully points to wsjt). These packets are coming from multiple ip
addresses.
Does anybody have any idea of what is going on?
Hi Philip,
That magic number identifies the UDP datagrams sent by WSJT-X, or at
least it should do but see below.
The payload format looks very like a valid WSJT-X heartbeat datagram but
the content is not right. If decoded as a WSJT-X heartbeat datagram it
shows an identification as MSHV v1.42 . I am going to guess that Christo
(LZ2HV) or some hacker has "borrowed" the WSJT-X UDP message protocol
and used the same magic number, that may be ok if he is trying to
communicate with WSJT-X but not otherwise, and I can't see any reason
why MSHV would need to do that!
Maybe Christo is trying to upgrade MSHV to post MS spots to pskreporter
and needs some guidance on how to do that.
