I recently started noticing an unusual problem with my now 2 month old
Mark-V. I wondered if anyone on the list has seen this before I call Yaesu.
When I transmit, especially using full break-in CW, I notice that the PO
levels will peak at 400 W and then fall back down to whatever level it is
actually putting out. I thought this was odd. After trying to rule out a
few things (I first started noticing it when using the FTV-1000 on 6 meters -
the HF PA section isn't even supposed to be powered so it really got my
attention) I finally found out what is going on but I don't know how to fix
I ruled out the FTV-1000. With it completely disconnected the symptons still
happened. I finally noticed that it only seems to happen when the DUAL
feature is off and you are only using the main VFO. Everytime I transmit the
SUB RCVR indicator comes on and the S-meter on the sub-receiver is activated
(and this is when the sub receiver is disabled - the TX and RX are both set
for the main VFO). If I activate the sub receiver the symptons disappear and
the PO readout operates normally.
Has anyone else seen this? I find it somewhat annoying but I am more
concerned that I don't damage the radio somehow. If anyone has any thoughts
on this I would appreciate hearing them.
Thanks and 73,
