Best outboard filter to remove tuning-up carriers?

[Don Buska]

Doc,

Find a Radio Shack DSP-40.  Less frills than the Timewave units, but it 
works well and has an excellent Heterodyne filtering.  RS doesn't make 
them anymore, but they appear on eBay or hamfests all the time.  Can be 
had for $20-$30 normally.

I have two in the shack and use them often.  BTW RS closed them out at 
only $25 many years ago.
