Re: FST4W and 22M now working in version 3.0.2

Look in wd_template.conf for explanations of the format.
During startup WD now checks that there is enough space in the tmpfs /tmp/wsprdaemon file system for the wav files recordings

### Following the time are one or more fields of the format 'RECEIVER,BAND[,MODE_1[:MODE_2[:...]]'

### The optional 'MODE' arguments specify one or more packet decode modes:
###    W2     => legacy WSPR 2 minute mode (the default if no modes are specified)
###    F2     => FST4W-120  (2 minute)
###    F5     => FST4W-300  (5 minute)
###    F15    => FST4W-900  (15 minue)
###    F30    => FST4W-1800 (30 minute)
###  For example "00:00   KIWI_0,630,W2:F2:F5  AI6VN"   specifies that KIWI_0 should tune to 630M and decode WSPR-2,FST4W-120, and FST4W-300 mode packets
###  Specifying additional modes will add to the CPU burden of the system and even more significantly to the peak usage of the /tmp/wsprdaemon tmpfs (ramdisk) file system
###  So if you specify F5/15/30 modes, run 'df /tmp/wsprdaemon' while running WD and adjust the size of /tmp/wsprdaemon in /etc/fstab to ensure there is at least 20% free space at all times

Hi Rob

3.0.2 has been running drama-free on my Pi4 here.  I will look to see what is needed to enable  FST4W. Is there a sample config or a README to help?

I know that in the recent past Jim WA2ZKD has installed WD on his odroid systems.
WD 3.0 includes the option for you to configure it to give me remote access if you need installation help.

Hello Rob,

great news! I am running the monitor at OE3XOE, at the moment using DigiSkimmer for WSPR and FT8. I will try V3, but I would like to use a Odroid XU4 instead a RPI4. Do you have instructions to install on this hardware?

The new Wsprdaemon version 3.0 software running on 20 sites from Maui to Europe is configured to simultaneously decode and report to WSPR-2 and all of the FST4W-xxx modes on 630M and 160M. i.e. only one Kiwi rx channel is needed to decode all of the modes in every WSPR cycle.

While Spring and Summer are not optimal for those bands, I am seeing FST4W-120, -300 -900 and -1800 spots in Europe and on the East Coast.

On 2200M AI6VN/KH6 in Maui, N6GN in Colorado, and WA2TP in New York are decoding all the FST4W modes.

I expect that soon many the 50+ top spotting stations will be running Wsprdaemon Version 3.0 and extend FST4W listening coverage worldwide.

Hopefully that many FST4W listeners will encourage 2200/630/160 beacons to start transmitting in those modes

The Pi4 has just enough CPU to decode all 15 WSPR (i.e. 22M) bands and all of the FST4W modes on 2200/630/160M.

'git checkout 3.0.2' will get you the latest build (currently
It is compatible with your existing config files, but to decode FST4W modes you will need to add specifications for them to your schedule.
