Weller WE1010NA

I am using a cheap Chinese clone workstation (Aoyue), it works ok. The only minor issue is that sometimes there is 60Hz hum from the transformer block.
For the same money as Weller, you can get a clone, AND an SMD rework tweezer iron. My bench has these two, and a small hot air gun with digital control (also Chinese from Aliexpress).

I saw some newer irons with the regulator built right into the handle. You may consider those if your work area is limited.

Adding a external I2C makes code change easier save for adding that hardware.
For me its a likely first way to go as then I can have more EEprom than 1K,
that gets rid of a boundary.? ? Doing that for some is out of their reach.?
Either way the code changes.

Yet doing it in software using existing hardware might be more palatable for
non hardware people.?

Just saying.

I am ready to replace my 30 year old low power soldering iron. I think I have 'typical' ham requirements - i need to do some SMD mods on my sBitx boards, and then do PCB kit assembly and some cables.

I think the Weller WE1010NA soldering station looks pretty good. But there seem to be a lot of soldering works station brands I never heard of for much less cost that have more features. Anybody care to guide me towards a good choice?

Whats forgotten is all the signals and how they can mix unintentionally.

ubitx you have:
carrier osc (11.059mhz, 12 before that)
SI5351 osc ~25,000,000hz
first conversion osc (~56.059 or ~33,941mhz approximately)
USB device on nano board 12mhz
atmega328u? ?16mhz?

figure out all the possible sums and differences... its ghastly.

Here is another set of schematics and pictures for V5.

V6 may require trace cutting to the high side of the volume pot.

You have to add the circuit on a low audio level.
Mine is connected directly to the mixer sinse it contains a low noise amplifier.
For the circuit, see
Depending on your rig, it is likely you have to cut a track or a wire.

HI to all.
I have uBITX V6 with Nextion display and CEC Firmware.
I made this adapter:
https://ubitx.net/2018/02/28/agc-mod/
I am wondering how to connect it to my RIG. Do I need to cut the leads somewhere on the PCB or can it be connected to the existing connectors?
Every help is welcome.
Thanks.

Ah yes. ?Helge Grandberg’s designs. ?Always classic. ?

i agree. I have parameterized the eeprom write/read in the 2.0 branch I am working on. So using an eeprom emulator to flash should be “easy”. I just never did it because I added the i2c eeprom chip and avoided having to support another library.?

So someone could take what I did and retrofit it to the 1.2 version or just fix the nano every implementation I have. I just have a few things on my plate at moment or I would do it ?;-)

Mark,

That's worse.? Your intent was in the right place.?

The problem is the person that needed that help is 6 months gone.
Perception, consider that.? ?The commenters stress is palpable.?

Mark,

To make a point.

"JPEG has excellent compression methods; a file compressed at ......" and so on.

There is another way to say that... are you so stupid as to not be aware of JPG
compression?" Yes that patently offensive but certainly the same content and
some of the feel.

Another way to say that is "We need to compress those images and jpg does
that for users with slow feed.".

Does the latter have a better feel?? It certainly conveys the need.

I think everyone here knows about JPG and its compression capabilities.? Its
only a 30 year OLD imaging standard.

I would hope that the document would be compressed maybe even zipped
for size.? Compression is over 40 years old and goes back the the CP/M days.?

However, the initial images are what I was talking about, not the delivery means.
They need to be of good quality meaning in focus and close enough for detail
so we can use them, all done prior to delivery.

We have had a few images that were when enlarged were just to fuzzy to read
and left people guessing rather than understanding early mods.

Not being picky or grumpy or even a bitch.? One thing is required, what is needed
and?to what extent especially for those inexperienced with a soldering tools.? We
have an audience that ranges from new operators to experienced engineers.?
We need to be able to help those that may feel in over their head.? That
includes pulling them up, helping them learn and do, without being condescending.

If this seems harsh it was not meant to be, but no question, It needed to be direct.

Well,

All I can say is I'm sorry I brought it up!

Mark,

That was true, but the Nano Every has so little EEProm you have to
use flash to store all that...? But it has 16K more flash.

So if you using a part that has limited EEProm you need to look at other capability?
to achieve the same result.

So 'CEC software would need some work for the flash case.? That can be done likely
using similar code.

To Dr Lee’s credit, kd8cec does a pretty good job of not wasting Writes to eeprom. For example, the last frequency and mode use on each band and specifically for vfo a and b are stored in eeprom. But the writes are delayed for several seconds to make sure that the frequency was of interest and you were not just scanning.?

The uBITX memory manager he wrote also only writes changed bytes. So I suspect most of us will be sk long before we use up 100k writes. :-)

Mike,

I have a thick hide and a strange sense of humor.
I though Gerry's comment was kinda funny.

I know the forum has no context for attitude or state
of the other guy.? Learned that back in the days or Arpanet.
Emoticons help but I used to use DCL notation like...

Set user /state= sarcasm_on
? ur kiddin!!
Set user state= sarcasm_off?

You input is welcome here...

IF memory serves there is a lib that allows for a reserved area
of flash with wear leveling.

With the Nano Every there is 48K of flash minus the bootloader
so using a K or two is not a big deal especially if you only copy
back if the contents actually changed.
