MFJ-1026 Noise Canceller Tests At VA7MM

courtesy: www.mfjenterprises.com/

Mark, VA7MM, has been testing out his newly-acquired MFJ-1026 Noise Canceller and has provided several videos of the noise canceller in action.


Like so many other hams, Mark's suburban location has seen a gradually rising noise floor and the noise heard in this video is from an off-site location within his local neighbourhood, located about 400m away.

The noise canceller requires a separate 'noise antenna' in order to cancel any noise on the main receiving antenna and for all of the tests shown below, Mark's noise antenna was a Cushcraft R-7 vertical while using an Icom IC-7600 transceiver for listening.

Test 1 shows the noise canceller being used while listening to a broadcast station on 6.0 MHz:


Test 2 shows the canceller's effect on raw noise while viewing in Spectran:


Test 3 shows the canceller's effect on a 40m CW signal:


Test 4 shows the effect of just the IC-7600's noise blanker on the offending noise:


Mark's comments:

Living in the noise cloud one must resort to special measures to use affected portions of spectrum. I recently purchased an MFJ-1026 noise canceller and have been testing the unit and have attached videos demonstrating the unit’s performance. You will see examples of raw noise, SW broadcast and 40 m CW signals with the unit being switched in and out. Also for comparison is the noise blanker in the IC-7600 failing to eliminate the same noise. 
 
Conclusions:
 
- the unit is able to eliminate noise in most instances when adjusted properly
 
- the noise sense antenna is critical and several different switchable noise sense antennas may be required for good performance
 
- setting up on AM mode with Spectran helps with fine adjustment
- it outperforms the radio’s noise blanker in all cases tested

With proper tuning and set up, it looks like the MFJ-1026 can make a worthwhile improvement in unwanted noise reduction.  Mark will also be testing and comparing a Timewave ANC-4 Noise Canceller with the MFJ and any videos received will be published here.

Hamvention Is Here – ETH069

With Hamvention already on top of us, I figured I’d throw my two cents worth into the mix with everybody else’s. In this episode of the Everything Ham Radio Podcast, we talk about some of the interesting things that are going to be going on at this years Hamvention at it’s new location in Xenia, OH.

DARA teamed up with The Miami Valley Mesh Alliance (MVMA) to setup a Mesh network on channel -2 at 10 MHz bandwidth.  The SSID is AREDN-10-v3.

We talk about all of my fellow podcasters/youtubers that are there and what they have going on and where they are at.

Lastly, we discussed some of the interesting forum topics that are going on during the weekend. To listen to the episode as well as check out all the links and further information on the topic, check out the show notes at:
