I gave my new T1 a workout operating /VE3 last week, and found an
oddity. Sometimes pressing the tune button and sending dits or dahs
doesn't do anything but flash the green LED. Taking the battery out
doesn't dix it, but a band change and a retune and then QSY back usually
makes it start again.
I noticed that the reported SWR on the 817 was full scale when this
happened, and being an adventurous soul I upped the power from LI to
blinky-LIII and got it to tune, sometimes.
One possible explaination is that the tuning is starting from the
current network settings, and when the resulting SWR is too high, the
817 high-SWR foldback is cutting the power way back. (A tap of the PWR
button on the T1 also showed no output, but it's not fair to use the T1
to test itself.)
Another possibility is that I have an intermittent or cold solder
joint.
I suspect that if I had remembered to bring the band-data cable I would
have encountered fewer problems, but even populating the firmware memory
table seems like it would have this as a bootstrapping problem on a new
antenna.
I am not sure what to suggest for a firmware change, but wanted to
report the phenomenon.
