A preselector is simply a band pass filter. A splitter is….. a splitter.

Just curious, why do you have an eight way splitter in line to the receiver. The preamp is there to offset the loss in the splitter. Try eliminating both, but not the preselector.

I'm curious what the 8-way divider was feeding in addition to the DR-2X??

That 8-way split was integrated into the Sinclair Preamp.? See attached pic.

Can you please elaborate on preselector vs splitter?? I assume you're calling a splitter what I've been calling a preamp sure to the split output.? Is a preselector then a receive amp without the integrated split?
Thanks.? I come from the CATV world prior to ham radio.? The splitter terminology is very familiar, but every little corner of the RF world uses just slightly different language at times.? Was just checking.?

I wouldn't have guessed that a preselector was a bandpass instead of an active device.?

Thanks for all the great info folks.? We're on the right track now.
