[TenTec] Eagle minor woes

[John Bescher]

Mike,


I'm no expert but I have an Eagle and it has never let me down.  Then again, 16 hours straight, I'd be malfunctioning, not only the transceiver.


Were you using a digital mode that has long duty cycles?  As a preventative measure, why not direct an external fan on the transceiver?  Noisy, yes, but maybe that will eliminate the timeouts.  I'd also check the vents on the Eagle are clear and non-blocked by any external gear. Yes, I know, obvious, but a lot of problems are due to obvious reasons.


Lastly, yes, the behavior you mentioned could be caused by excessive heat to the Eagle's boards but it could also happen due  to RF entering the transceiver.


If this continues, not a good sign, as  you know, excessive heat can damage your transceiver.  When is the next 16 plus  hour contest for you?


Good luck.  The Eagle is a fine transceiver.  I'm sad Tentec is no longer producing Amateur Radio products.

Folks, I ran my Eagle for about 16 hours straight in the IARU contest
yesterday and as the hours wore on it got warmer with the fan coming on more
often.  Of course here it is doing exactly what it is supposed to.  What I
did notice is that towards the end, it began to lock up (tuning dial had no
effect, would not transmit).  I was able in each case to bring it back to
life by power cycling with a brief off period, but of course that sends the
COM port in the laptop into never never land and it took several gyrations
with enabling/disabling/enabling the port, pulling an reinserting cables,
more power cycling, etc., to get the radio to talk to he PC again (N1MM+
logger, about which I can't say enough nice things). Anyway, sort of under
the heading of first world problems, what's the list wisdom on why the Eagle
is going kind of brain dead now and then, apparently when warm?  Is this
"normal" behavior, "to be expected" of a complex hardware/software system,
or is there really a cause we should be looking for?  Thanks for your
thoughts and 73, Mike W2IY
