Mustool MT883 Soldering Iron Review (kinda long)

 

This is a 117V, A.C. line powered, temperature-regulated soldering iron available from Banggood and other vendors.

Positives: IMO, this is a fine tool for the price (~$9 - $20 dollars, vendor dependent). The overall appearance and construction quality is very good. I like the light weight of the iron and the flexibility of the power cord. I also like the user interface (LCD display and controls). This is an iron I can put in my field toolbox and not need to carry around a soldering station. I also like the fact that it uses readily available Hakko (or equivalent) soldering tips.

Negatives: I gave it 1 star for quality on Banggood because, unfortunately, mine will not function properly as received. It heats and regulates the tip temperature however the display cannot be calibrated for the correct readout as the required offset is out of range of the iron's control system. This is NOT a design flaw as I've used Doug KI6DS's MT883 (also purchased from Banggood 7 days after mine) , calibrated it with ease (I own a soldering tip thermometer) and successfully soldered with it. We used both irons at this past Friday's QRPacificon Buildathon during construction of participant's Pacificon Special Antenna. I simply used a "fudge factor" to set mine to the correct tip temperature. After which it functioned acceptably; only the temp. display was incorrect.

Instructions: Seem to be unavailable in electronic format on the 'net. If one is sight-impaired, prepare to use magnification to read the the white-on-black instructions printed qrp type size on the back of the package. I got through it, with some difficulty.

Considering the low price I paid for this tool, returning it is not worth the trouble of complying with Banggood's ridiculous return policy requirements.

I can recommend this iron, especially for novice electronic hobbyists, PROVIDED that one is willing to accept the possibility of receiving a defective product.

As Wayne Green used to say, "Caveat Emptor".

Re: QRPGuys DSB Digital Transceiver

 

Got it built, and it goes thru all the paces of receiving and transmitting on both 30 and 40 mtrs, but wont receive .
I hear noise and a little am harmonics, but no ft8 signalsand no real band noise.

Any ideas?Terry w6leo

Hey Michael,

Based on email, more people liked it than didn't - but a few *really* didn't like it, and that's putting it mildly! See you on 40m CW in a couple weeks.

I'd be very happy to work the guy that wrote "My most fulfilling FT8 QSO?" any time! Thanks John, that was a good chuckle :)

no, just looking for a time when there might be a lot of people on. East coast was good to me between 0300 and 0400 UTC yesterday so thought I might give that a shot. But I'm not totally stuck with that time slot!

Terry,

It appears that all of the files and photos are already gone.? I can't seen any of those on the 5 Yahoo groups that I own.? Sad!? :-(

Re: OT: Yahoo Groups is going away

 

The entire message history is going away. All that will remain is
forwarding of current messages. Plus all the files are going away. There
won't be enough left to be useful.

It's not really a surprise. Yahoo aka Oath aka Verizon has been neglecting
Groups for years.

Re: OT: Yahoo Groups is going away

 

Mike,? look at the top of any yahoo groups page. It says it there:

*Attention:* Starting December 14, 2019 Yahoo Groups will no longer host user created content on its sites. New content can no longer be uploaded after October 28, 2019. Learn More <>

In short,? any files and photos on any yahoo group will go away as of December 14 so if there is any content you want or need from any of your yahoo groups you had better get it now.? It also sounds like email history will go away in December but was not sure about that one.

Jim Pruitt
And this was posted to a owners/moderators groups.io group for which I am a member concerning the yahoo announcement:


Understand what's changing in Yahoo Groups

Yahoo has made the decision to no longer allow users to upload content to the Yahoo Groups site. Beginning October 21, you won't be able to upload any more content to the site, and as of December 14 all previously posted content on the site will be permanently removed. You'll have until that date to save anything you've uploaded.


What features will go away?
<>

* Files
* Polls
* Links
* Photos
* Folders
* Calendar
* Database
* Attachments
* Conversations
* Email Updates
* Message Digest
* Message History


What will happen to the site?
<>

The Yahoo Groups site will continue to exist, however, all public groups will be made private or restricted. Any new group members will need to request an invite or be invited by an admin. Admins will still be able to manage various group settings, though some functionality will be limited.


What will happen on October 21st?
<>

On October 21st, you will no longer be able to upload any content to the site. To share info with members of your groups, you'll continue to be able to do so via email.


How can I keep my Yahoo Groups content?
<>

Photos and files can be saved <>?right from the Yahoo Groups site, or you can download your data from the Privacy Dashboard <>.



Will I be able to use Yahoo Groups going forward?
<>

You'll still be able to communicate with your groups via email and search for private groups on the site. In addition, admins will continue to have limited access to group settings and administration tools.

Re: PCB material fabricated NanoVNA chassis

 

Fantastic job Ken. I think your design is more practical than a printed one and also provides shielding.
