hi,

i recently purchased an very nice drake r8 my choice over the icom r75
- i don't regret my decision one bit - a great radio and along with my
palstar one of the best i have owned and i have owned a few. my
question is will an r8a buy me much more in terms of better DX and
audio, sync detection etc. i have heard the build quality is a bit
better on the r8 and also uses the original drake decoder that was used
in the R7. besides these things, will the r8a buy me much more?

The R8B is a much better upgrade than the R8A. The B version has
sideband selectable sync.

Would some of you receiver experts that lurk here please explain to me
why the selectable SYNC on the R8B is any differient than using the PBT
while in SYNC on the R8A.

Now a receiver that had a limited PBT range ie.. JRC I can see that it
would not give true USB/LSB shift. But on the R8A the PBT will cover
more than the 3khz bandwith on each side band.

Take 5.070 mhz now at 02:18 utc. There is a a pinging sound on the USB
side but not on the LSB. I engage the SYNC in AM mode 6khz filter & I
hear the ping with the PBT set to 12:00 oclock setting. If I slide it
slowly to the Left or the LSB I do not hear the Ping. If I shift the
PBT to the right or the USB & the ping is there.

Is this not the same as selecting USB or LSB on the R8B SYNC ?????

PBT is similar in result to using side band selectable sync but the sync
is generally more effective.
