Let me first say that it's a pleasure to have a conversation with you
for a change.


I would rather discuss technical issues instead of the constant nonsense
that gets posted daily. We possibly could have gotten off on the right foot
if you hadn't been spamming the group when there is a group just for listing
your items. Your tag line is more in keeping with Usenet manners (as is
bottom posting, but I'm not that anal).

That said... you are certainly entitled to you opinion on
the SSB delay. A switchable delay is really quite subjective.


Let me pose this question. Why would most amp builders put a delay in if it
were not necessary? From the old tube boat anchors of the past to the modern
units of today. Last winter I built an EB63 and attempted to do the same
thing and I ended up switching the delay as I could not find suitable middle
ground. Maybe I'm just picky, but I like my equipment to respond in a
certain way.

If you
really had a problem with the SSB delay... you could opt for no delay
and use the SkyWave's multiplexed "hard" keying feature. This allows
keying the amp when the mic is depressed (in any mode) and holding for
as long as the mic is pushed.


From what I see, your unit has a COR circuit, which means that it must sense
the carrier. How is the relay operated in SSB mode with no modulation or
carrier? Are you sending a modulated signal in SSB mode or are you adding a
small amount of carrier to the SSB? Something is operating the COR circuit,
how about pointing out what that is so I don't have to restudy the design.


It requires a slight mod to the radio...


Like???? Give me an example of what I need to modify in my 148.

but no extra wires between radio and amp.


A two pill really doesn't need to be remotely operated, I just gave that as
an idea for those that might want it remotely mounted.

Many of the hams running the
SkyWave are using this feature.


Most hams that buy your unit will never use it on AM.
