[R-390] Longwave Products 6 Khz AM filter for R390a by Dave Curry.

[Albert Santangelo]

I installed the Dave Curry 6kc filter into my R390A in place of the 16kc filter last year and am very pleased with
it. The installation took me about an hour, and the supplied instructions were very helpful.

For me, the 4kc filter can be too narrow sometimes, and the 8kc position can be a little too wide when dealing with
QRM either on the ham bands or SWLing. So the 6kc filter fills in the gap there for me.

I see higher gain in the receiver when using this filter, of about 10db, perhaps due to the aging of the original
mechanical filters in the set.

It is a pricey option, but I could justify it for the most part because I didn't have to pay a high premium for the
receiver.
