The optional filters also fit the 857 and are Collins mechanical
filters, not crystal filters. For certain the CW filter is more
effective at lifting a weak signal out of the noise than the DSP filter.
There is an unused pin on the 857 power connector that when grounded
puts its RF output to 20 watts or less for 897 battery mode.

Fact is, there are lots of radios about that do some of the same
function as the Scout, some better, some more versatile, some not as
good depending on your criteria: weight, power drain, continuous
coverage, VHF and UHF coverage, minimum operating voltage, SWR
tolerance, noise blanker performance, convenient user interface, and
cost. Virtually none of the radios mentioned in this thread are horribly
rotten, they all make contacts repeatedly.
