Here is a modified version of wsend2v2 which has
a test mode

 http://abelian.org/tmp/wsend2v2.exe

(File size 20992 bytes).

Enter a symbol period and press 'Test' and it toggles
the relay on/off at the symbol rate until you press 'Stop'.

You can use this to tell if the relay is working reliably.

Set a symbol rate of say, 1 second and run the test and listen
for a while to see if it ever misses a 'tick' or if the ticking
is irregular.
