I'm certainly not saying that you don't need a delay on SSB... and you
sound like the length of the delay (for SSB and no delay on AM) is a
priority for you. That's fine. That's why you would need to use
SkyWave's mutiplexing keying feature. If you send me an email... I
would be glad to send you the details of the mod for the radio. Keep in
mind that this mod doesn't work for other brands of amplifiers. It
allows the amp to key (in any mode) when the mic is pushed... no matter
if modulation is present or not with no extra wires between radio and
amp.

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.

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.
