Re: Easy, Inexpensive Cooling Fan, Excelway Case
I was in a hurry when I put my fan in so I went with this one and spent about as much for the grate as your fan cost.? Spending $6 on that fan felt almost extravagant but it is silent at least to my ear.? I don't have a good way to test for interference but I don't see anything different on the WSJT waterfall or hear any noise on my speaker which as all I have to go by.  --

The fan is aurally quiet enough, but the case resonates a tad with it, so you can hear it.? If I wanted to do some vibration isolation and case panel damping work I could probably make it unnoticeable. I have not noticed any noise on RX, but I'll do some fiddling to see if it gets picked up.? Any ideas for a good test?? I suppose I could use the RSP1A to look for its signal?

I will probably upgrade the heat sinks and the fan will be mounted either on the top or the interior side of the case. I'm not a big fan of top vents for cooling. I may mount a small speaker on the top with holes for that, but the speaker will be "sealed" to the top. (The larger Apache case will likely have a vertical separator, with the paddle, headphones, and battery pack in the other half. I will probably mount the fan on that vertical partition. That way, if I spill something or it's starts raining, liquid won't get into the xcvr section of the case.) I will need some kind of cooling as the JackAl board draws enough current to heat the regulators up a bit.

I'm assuming you will be operating with the case open.? I haven't done the math but I would think unless you fall asleep on the ptt or your key I doubt you would need anything more than some vent holes in your acrylic plate.? You could upgrade the heat sinks for insurance.? If you really want a fan why couldn't you just put in the acrylic? ? --

This is the little briefcase I have.? It came from Harbor Freight:
The board fits with plenty of space.? There is also pleny of space for a battery.? At only $14,?I thought it was a good buy.

I am toying with the idea of a setup like that or maybe an ammo box setup where I build a metal panel to hold the radio either facing the long side like yours or possibly facing the edge like a typical radio so I can maybe throw a mobile dual band rig in there with it. I'm not sure where I will end up yet.

I'm thinking about using an Apache case from Harbor Freight. However, I need a way to cool the PA's with some kind of fan, but without destroying the watertight nature of the case. I'm going to use a clear acrylic top for all external connectors/controls. I'm pretty sure there will be enough room for a battery pack, too.

Thank you for the fast reply. I got to the next page of posts where My post was and read your post above about which one to buy. ?I promptly deleted my post, not promptly enough it seems. ?Thank you and sorry for reposting already asked questions.

Here's my attempt at a 'transportable' uBitX. The box is a 'toy' briefcase and the display is mounted with a ribbon cable on the top surface. The gaps and perforations are for air flow ?as there is a manually switched fan blowing across the heatsinks which is used for continuous digital modes.

Re: Schematic . . . What Schematic . . mine?
TNX Bill and I think Vince did the same thing.
I received some boards from China yesterday that I forgot I'd ordered.
I had to go to Paypal to see what 2 of them were.
Looked liked great boards, but I didn't know what they were. Looked like maybe an amp of some sort..
Yea they were . .? Dynamic mic preamps.
Wired one up to the uBitx and got great audio.
And yes . . . I did make a notation in my notes.
Like they say . . . War is hell . . .so is getting older . . .? HI HI

Thanks for all the replies.
I will do the raduino update as well as the mod to mute the LM386.
Should fix the problem.
Great to have all the support.
Cheers

Powering the uBITX down, reconnecting to MM and reading and decoding does not show the WSPR settings as I originally tried to write. I am using Windows 10.
Just what is the Match Data box in MM actually doing or informing me about? No error messages from MM, only EMPTY DATA from 1.08 Raduino?when attempting to set Beacon Mode even after powering Raduino up again.? Bob

Here is my uBitx. The display is too bright and came out white. I
use the RF gain, AF gain, tuning, band selector, Function and ANL
controls at the moment. I reprogrammed the Raduino so that A7 reads
the position of the band selector switch and changes the band. It is
quicker and easier then using the push on the knob. Right now,
Function is just on/off. I might have it change the sidebands, but
there are no more easily usable inputs on the Raduino. The MIC plus
in the REC SEND jack, the phone jack works, speaker output is on the
back. I am using ANL to enable the 50 linear amp. The S meter works.
I have no plans yet for the preselector, cal and car reset
functions.
The inside is still a work in progress. I should get my accessories
PCB in about a week and hopefully will be able to report on it later
in the summer. Right now, the linear is only usable on 20 meters.
The select able LPFs for the amp are on the new PCB. The protoboard
has the prototype S meter, AGC, mic AGC and audio amp circuits on it
and will be replaced by the new PCB.

Re: KD8CEC Nextion - Hardware Question
#ubitx
The S-meter and PO use pin A7.? You will need relevant hardware mods to use the meter. Both functions can use the same pin since one only works on RX and the other only on TX. However this doesn¡¯t prevent use of the display for all other functions?

I just ordered a display to experiment with the KD8CEC tft firmware. Looking at the pictures on his blog I can see that it has a bar for showing power output. How does this work as the stock ubitx does not have that option.
Moreover, the description on the blog says you don't need any mods for the tft display to work, it looks really great and very very professional!
