A colossal waste of money  Time owned: 3 to 6 months
Never synchronized, sent it back to MFJ to get it fixed had to prod them to do anything weeks after, When I finally got it back , no dice. I have other devices that sync with WWV so it's not my location. Don't waste your money, I will use mine as Psychedelic lights for Disco on!

A friend gave me one of these. It would not sync up in my basement shack even though I placed it near a window (walkout basement). On the main floor it synced up fine. It's a novelty item. Quality is typical MFJ (silk screen pattern is crooked, cheap materials). I suppose it works as advertised, but as others pointed out, you can get the same thing on your computer at much less expense Not something I would purchase,but others might find it useful if you can get it to sync.

Just OK, at best  Time owned: 3 to 6 months
Bought one about 4 months ago, it synched once, never did after that. Failed nearly all the self-tests/diagnostics included in the manual. Finally called MFJ, customer service was great: sent me out a replacement w/o asking for billing information, received a new unit before I had a chance to send my original back (they paid for return shipping). The new unit synched once (on internal 9V battery), then stopped doing so for about a month, quit with MFJ transformer. Interestingly, had a complete power outage at the house, the unit went back on battery power, and (guess what?) synched again. I'll be darned if I can explain it. I don't know how long the good fortune will last, but if I had known about this experience long ago I would have not bought the MFJ 890 in the first place.

Not to bad.  Time owned: 3 to 6 months
If you have a PC, you can get the same thing on your screen with free available programs. But the MFJ DX monitor is a cute gadget for the shack. Downside... Power input jack is on the front (?). It has a 9V battery for power back-up, but without power it will die in a couple days, since there is no way to shut it off completely. It's a cute gadget and works as described. But, one of the last things ou really NEED.

Mine works just fine!  Time owned: more than 12 months
This is a cool, little gadget. I bought mine soon after MFJ put them out and it's worked very well since. It's a neat gizmo that can help guage propagation behavior. Very creative!!

Good idea, but poor product...  Time owned: 6 to 12 months
I bought one of these, and it worked reasonably well for about a year. I did find it useful. Then it just quit. I called MFJ, and they told me the replacement parts would cost about the same as a new replacement. There was no offer of warranty consideration. So I said goodbye to this piece of Mighty Fine J... (you know the rest).

Disappointing, for sure.  Time owned: 0 to 3 months
I think this product is a neat idea, so I bought one at the local HRO.

It never sync'd to WWV after being left on for a couple days. I have an "atomic clock" which sync's just fine, so I don't think it's my location...

I called MFJ and got an RMA to return it to them. I was told it would be replaced because it was brand new.

SIX WEEKS LATER I had not heard from them, so I called again, and was told that my new replacement unit was enroute.

A couple days later, it arrived. The enclosed paperwork indicated it had been "repaired" (despite being told it would be replaced in two different telephone calls).

And it still will not sync with WWV.

Am I disappointed? Very. Poor product and poor and misleading service.

Neat Gizmo for your shack  Time owned: 0 to 3 months
The MFJ-890 beacon monitor is a very interesting clock indeed. The way it works is to show you what beacon is on at what time. It contains a WWVB receiver (60 Khz) that keeps it in sync to the actual time. To use it simply turn the selector switch to the beacon frequency you are interested in (20,17,15,12 and 10 meters) and tune your receiver to the same frequency and listen to your receiver to see what beacons can be heard.

In use it seems to work well. It locks up most of the time to WWVB, if it canít hear the WWVB signal you can manually sync it by pressing a button while watching an accurate clock or listening to WWV.
