I also use the a500Hz filter on my FT-100 in digital mode with 1150 Khz shift
so that I can tune the true frequency.The results are by far better since.Best

I am using a 500Hz filter on all radios...
Really makes the difference, also fine for PSK500.

It may be worth investing in a narrow band filter to help your decode..

Subject: [pskmail] QRM ??
Hi,
lately I have a lot of QRM during pskmail operation. It's nearly
impossible to finish a data transfer and so "Abort" is mostly the end.
I've looked around a bit in the Internet and found that Robust Packet (
http://robust-packet.net/ ) uses the 10.147,30 MHz USB for it's
transmissions. Is ist possible this caused the QRM, has anybody made
similar expierences ?
I've attached a fldigi screenshot when the transmission took place.
To identify the signal I've looked about a Robust Packet sound file
example, but unfortunately I found nothing.
