All,
I breathed life into K2/10 #7372 (love that serial number) last night.
This is going to be fun little radio despite being a 15-year-old
design!
I noticed one thing that I wanted to ask the assembled experts here:
When peaking the TX BPF capacitors, there was a perceptible and
easily-found peak; but, if I got off the peak too far, the transmitter
power would increase rapidly to >10 watts as I tuned in the wrong
direction. This must be normal or expected? I did not monitor the
transmitter spectrum while doing this, so I don't know if it's a loud
spur that's normally suppressed or an amplifier somewhere is
conditionally-stable?
Secondly, and perhaps most importantly since the radio appears to be
stable in the face of the previous question, any suggestions for a
side carrying strap? In the archives, it appears that the IC-706
handle was popular. What about the handle for the FT-450? (I have to
place an order with Vertex Standard for some small parts for a Yaesu
HT and it would be nice to make the order worth their while by
ordering a handle at the same time.)
Thanks/73,
--Ethan, K8GU/3.
