A q multiplier is a crude way to increase selectivity. The Tentec
radios have a very effective pass band tuning that even with the
stock SSB filters in the 9 and 6.3 MHz IFs (where a q multiplier
would not be very effective) can get the bandwidth down under 100
Hz. The CW filter is also effective but not much more though it
is a little handier to operate.
