Old, but still very effective.  Time owned: more than 12 months
This is now quite an old analog audio filter but one of the best and easy to use, very similar as the Datong FL-2/FL-3.

Can be found second hand at low cost.

I use mine daily with my SB-104A.

Older Technology That Still Workd Great!  Time owned: more than 12 months
I have owned one for years. I use it with my older IC-740 which has a teriffic receiver on it, but when operating in close quarters as on CW or PSK31, there were a couple shortcomings in the receiver. It was great on PSK31 to narrow the upper and lower audio bandpass limits and simultaneously notch out a strong close in station. It improved reception too on CW even though I had the optional 500 Hz. filter.Yes a newer DSP filter would be better, but for what I paid at the time, it has served me well.

I like it so much, I recently purchased one on eBay for use with an old AM/CW station I restored comprised of an HT-40 and HQ-110. The Q-Multiplier on the HQ-110 is nice, but this makes operating CW with the HQ-110 a joy.

Great accy for the money  Time owned: 0 to 3 months
I recently acquired one of these to use with an HW5400. The HD1418 audio filter unit complements my rig very well; especially useful is the audio notch function - just the trick for reducing QRM from the tuner-uppers and SW stations.

The filter can be operated in peak and notch modes; independent bandwidth, peak/notch tuning and center-frequency controls are provided. The unit's response curves can be optimized for RTTY, CW and SSB modes.

Disadvantages? Since it's analog and not DSP-based, it lacks an effective noise-blanker function. No auto-notch, either...but for the price you won't miss it.

I plan to buy another of these units. Too bad Heathkit is no more; it would have been a fun kit to build.
