Top for cw! Time Owned: 3 to 6 months.
My old Drake TR4-C tube transceiver has no cw filter. The Dierking Audio Filter is just great. It pulls cw stations out of the qrm I couldn't receive otherwise. I also use the filter with strong stations because the signal sounds better. I haven't tried the filter with other modes but I would buy it again alone for it's cw capabilities.

abdicable Time Owned: 0 to 3 months.
Somtimes the Audio simply went off and came back, that was an error but they didnt want to repair it nor replace the whole thing. Customer Service shouldnt end with a Sell.. There was not much use for it, only for the Notchfilter was a bit useful but not enough. Its totaly overpriced for 200 Euro (about 280 US Dollar) and the advertising is exagerated. I regret I bought it and sold it in matter of Weeks.

excellent addition to QRP rigs Time Owned: 0 to 3 months.
Hi all - having in use the MFJ-1278B DSP for a dozen years now in the main shack, I needed a smaller and portable filter for the FT817. My choice fell on this unit.
Testing it thoroughly I am glad to inform:
- it greatly enhances the rather poor audio handling by the FT817, in general;
- it's capability to peak CW, PSK and other narrow bandwidth signals in a qrm surrounding is astonishing and most welcome;
- ssb, mfsk, rtty and other larger modes benefit from the same ease by which the user can narrow the received channel;
- it is easy to hook up, takes some minutes to prepare a soundcard link cable (3 or 5 Din-audio plug and 3,5 mm mono plug) and supply standard VDC. Basically no detailed instructions required for the normal ham.
All in all, it is well worth the investment; support by phone and e-mail was friendly, constructive and prompt. I would not like to miss this accessory any more.
