|Back in 1962 it took me forever to get the Novice because I am very right brained and learned the code visually. Later in 1970 and 1971 I got the General and Advanced at the FCC in Boston at 13 wpm. But, I waited for 5 wpm to come for the Extra. But, I like CW and my on air cruising speed is 10 wpm. After doing mostly PSK-31, I decided to try the 461 to back-up my CW - it's much better than I thought it was going to be. At first it copied nothing until I turned-up the volume to very high. I cured that by setting the sensitivity to max. It was then copying the signals a tad low in tone, so I adjusted the PLL. Now it copies most code and I use the 461's LED when tuning CW on my IC-746-PRO. My only minor complaint - the 9V battery cover was a very tight fit, maybe due to some sort of tape over some wires under the battery. All in all - I was surprised on how well it copies CW and I do recommend it.|

|Very good antenna for 20 meters|

|Works on my Shunt Fed Tower|
I took a chance on the MFJ 998 remote auto tuner to match my 63 foot shunt fed tower. It worked, it tunes a match for 30, 40, 60, and 80 meters (SWR 1.3 or better). I followed other reviewers’ recommendations to test the tuner inside on a dummy load to understand how it works. I also inserted a manual tuner to induce SWR to see how it would attempt to match on the various bands. I found the instructions complete and easy to follow. With the cover off the internal green LCD screen shows the tuner status as I was testing it. I only changed one default, Target SWR down to 1.3 SWR or better from the 1.5 SWR default setting. The tuner's Watt and SWR meters matched my external meter readings. When installed at the tower I found I had to tune from band edge to band edge on each band about 10 times for the memories to be set. Once set it only takes 10 watts and one second for the tuner to match to the new frequency on any band. After the memories were set I tried high power of 1300 watts. So far no problems at 1300 watts (CW). The tuner does have a failsafe of switching to bypass mode if more than 125 watts are applied for tuning. It worked. I accidently had the amplifier online and switched bands and transmitted. The tuner went into bypass mode and the amp tripped out. I applied 100 watts for the tuner to tune and then back to high power, all ok. Initially I had to use what MFJ calls the StickyTune option of turning the power off for 2 seconds then back on for it to initiate a new tuning sequence and a lower SWR to be memorized. Even though there is no remote display for the shack, if you know what to look for on your SWR meter you know what the tuner is doing. As you can read there is a procedure to be followed. I do have a good RF/DC ground on the tuner and have a coax feedline current choke (important). No issues so far.

|I used one of these antenna's for about 5 years and it work's well|
except for the clip on the end of the wander lead get's very rusty
after 3 or 4 months and has to be changed maybe MFJ could put a SS one on the wander lead.

|Purchased from R&L. received 2/7/14..in service 2/8/14 Controlling previously installed Ham IV Installation for USB pretty straight forward. Powered up, works fine. Fine tuned controller for DX4WIN and works like advertised. Only complaint(s) Front panel decal/sticker already pulling away. Some glue should take care of problem, but shouldn't have to rework quality. Biggest issue is the CCW button sticks incessantly. Could be due to front panel decal or could be installed crooked. |
Other than that...does what I want, much better than stock rotor control
|From: Doc C WB0FDJ|
|Long story short, this accessory does what it's supposed to. If you will only ever run transceivers then you won't need this. But for those, like myself, who occasionally break out an old EF Johnson Adventurer transmitter, or a homebrew QRP transmitter, you will want this. Hookup is simple, I use mine in the sensing mode and it works slick. I don't use it every day but I'd never want to be without it. |

|I bought the 9406 back a few years ago, and never got around to trying it out. Finally, in 2013, I hooked it up and tried using a wire vertical out of the antenna connector. It worked but with RF in the signal, no surprise there. I then hooked it up to a M2 Loop in the attic. There it works good, even with the inside antenna. Locally, I am able to work or hear out about 50 miles and I have worked the South and heard all over, during openings. The band conditions have not been great, but the 9406 does the job, what with the limited antenna. Have gotten good signal reports once I went on the 'tuned' antenna. I do recommend this rig. I started on 6 in 1961 with the Heathkit Sixer, this rig is just as much fun.|

|Very impressive performance on my Yaesu VX-6. From peaks in the North Cascades in Washington state, I've been able to converse with stations up to 95 miles away, in Canada. I highly recommend this antenna for it's incredible range. It's also lightweight - a nice added benefit. I toss this antenna (detached from the HT) in my backpack and carry it all over the North Cascades. Well made and rugged.|

|Great antenna for SOTA hill top portable, and Kayak QRP OPs. Adjust counterpoise for best SWR, and your good to go. Never expected it to work this well. Just ordered the 40 meter version as well. |

|Recently purchased the a new MFJ 1788. When the box arrived from the supplier ( DX Engineering), I noticed one side of the box had been opened and re- taped with clear tape.|
I first mounted the antenna on a 8 FT galvanized pole away from any objects in the back yard. I carefully read and followed all the instructions from the operating manual provided. Yes....I had to widen the holes on the vertical support brackets so the hardware would fit properly. That took 10 minutes with a cordless drill.
When I first powered up the control box, I could not get my " FAST" DOWN LED on the right to illuminate. First thoughts were of the quality control at MFJ. AFTER TRYING OVER AND OVER, and failing to get the antenna tuned on 20 meters I decided to take a look inside the plastic covers of the loop itself. I had read some blogs suggesting the checking of solder joints if the antenna was not working. So off the covers came. Within a few minutes I noticed one side of the internal loop wire had a cold solder joint. The end of the internal loop could be moved in and out of the solder joint freely. I resoldered the joint, remounted the antenna and presto.....all LED's were now working. I managed to somewhat tune some of the 20 M band but the SWR at best was 2:1. I had read in another blog that if your internal loop was turned out on one side compared to your 36" loop you may improve your SWR.. I tried it and WAALA," got an SWR OF 1:1 at a full 100 watts. Now the test...( I live in Florida) I heard a station about an S9 on 20 meters. I retuned to that frequency and attempted contact. Immediately I get as response back ...a clear 59 signal from Richmond Virginia. Happy I had made a contact I wondered what the antenna would do closer to the ground. I placed the antenna on the top of a plastic garbage can ( approx 24" in height) in the vertical position from ground. I went back to the radio found another station on 20 meters, retuned, gave out my call and again got a 59 response. He also was located in Virginia. When I told the contact about my antenna and that it was sitting on top of a plastic garbage can he laughed and said I can't believe it. ....that I was a little stronger than another Florida station in FT Lauderdale that was running a beam pointed at him. He was quite excited and started talking to others in his group asking if the could copy me as well.
Pretty cool. In closing despite the few hiccups...I am glad I purchased the antenna.
I just wish MFJ would place some emphasis on Quality Control. Oh yes one other thing.
I called the MFJ Technical Support number listed on the instruction manual for the 1788....A lady answered and told me that I had the wrong number and that MFJ has a new number and has for some time.
She seemed a little irritated.
Anyway, I hope this review helps. 73. VA3TKO
