Re: It's alive!

 

Awesome! Thats pretty quick delivery. Looking forward to mine arriving soon as Ive got some holidays coming up and time to spend putting it together. Hoping to take it portable to activate ?few parks.

Hi,

I am doing the same on ubitx

backing off the RV1 preset , to drive 5 watts into external Linear amp

?

Farhan can I have Drive pot mounted suitably on the rear panel, as it would make it easier to adjust drive on different bands

?

thanks 73

You can always turn down the preset on the predriver stage to let the rig coast under 2 amps, or... remember to speak softly into the mic.

Any suggestions for a power supply for the uBITX?? I am using an old laptop supply for my BITX40 but it is only rated at 2.5 amps and it looks like Ashhar's latest masterpiece needs 3a.? I've been through my junk cache in my office and basement without luck.? I still have to rummage through my stashes in the garage and the barn but I might actually have to break down and buy something.? Of course buying a replacement for something I think I have is usually the easiest way to find it.

Re: Small question about LCD mounting

 

Excellent job on that front panel Michael. My friend has the same enclosure. Two questions - 1) - how did you get the lettering on the panel, and, 2) - can the lettering be in white? My bitx40 box is clear and smoked plexiglass.
Thanks Tom VE3THR?

I ordered on Monday the 11th and in the same quandary. I am guessing we missed the first batch and will have to wait until whenever the 2nd batch is released.
No idea when that will be but at least we are on the list.

Re: It's alive!

 

My uBITX is progressing a little slower than some others.? After much contemplation
I decided to do the chassis thing in two stages.? First chassis will be temporary and
serve for initial testing and as a template for a yet-to-be-built aluminium box.

For the temporary chassis I cut some plastic sheet and used hot-melt glue to fabricate
a box.? It is necessary to measure carefully in order to have the LCD protrude from the
front panel and the heat sinks against the back panel.


?
This image shows the front panel with components mounted but not yet wired.? Labels
have not yet been applied.? The upper left LED is a RED unit and will show relative
antenna current.? The lower left LED is bi-color (Red and Green) and will be show
transmit and receive mode.? The upper right LED is green and will show when power
is on.?

Other images are attached to this email.? Hopefully they will be viewable by all.

The rotary encoder that came with my uBITX does not have mechanical detents.? It is free-running.

Rotary encoders that I got earlier from Ebay vendors look the same but they do have mechanical
detents.? Some have one detent stop per 2 steps and others have one detent per 1 step.? The
2-step types require a slight software modification to make them work best for tuning applications.

I did it with an encoder that I use to tune my PC with HDSDR.

It's a mess, but I have my ?BITX working now. I wanted to get it working before I put it in a case which is why there's wires all over the place as I trimmed none yet. That will happen when I move it to a case, which will likely be the plastic case from Banggood. I just finished wiring it, so I haven't had a chance to really use it, but just tuning across the band it seems very sensitive. I'm using headphones so there's plenty of volume. The encoder appears to be optical (?) as there is



feel of detents when tuning. To all those who are waiting, it will be worth it!!

Re: uBITX Display Separation Cable

 

Is the display missing a couple of digits?
Re: uBITX Case

 

I'm by far an expert at this, but what about using support structures or breakaway columns as the case is being formed?
?

Or buy a pack of male-to-female jumper wires labeled for Arduino use (to make sure you get the right header pitch and pin size) and tear off only the 16 you need.

My pack of 120 (40 male/male, 40 male/female, 40 female/female) cost $10 on Amazon for ~6" long and have been very useful while soldering up other connections for mods.

At about 7" x 6" x 2" tall that's a pretty big item to 3D print IMHO

The BITX, whether u or not, can benefit from this :) . Makes for more case and panel options.

If he follows his usual approach, Sunnil in India is likely to produce a custom case for the uBITX, as he has for the BITX20? and BITX40. His prices will be difficult to match, I suspect.

Hello all,?

I'm new to the group. I was sent here from a where they were talking about a case. I work as engineer/drafter at sheet metal fabrication company. We design, manufacture and powdercoat all sorts electronic enclosures for customers.

If I made the cut-off, I will hopefully be receiving a ubitx soon and I will be designing a case to fit the ubitx. There is a possibility of mass producing cases. It could something along the lines of but designed with stand offs for the board and screen, speaker cutout (we would have to agree on a speaker) and powdercoated mini texture black. Once I get a design I could get it properly quoted and let you all know the price. Of course it would have to be on a pre-order basis.

Price will obviously be effected by demand, the more that can be made, the cheaper it can be. Other cost savings would be the removal of press fittings and coatings.

Let me know what you think

uBITX order enquiry

 

Ashhar,?
thanks for bringing the uBITX to the world.?

A quick question - I ordered and paid for one on Sat, 9/12/17.?
I haven't received any comms about it so far. Do I need to enquire about it ? or just sit tight and wait?

Thanks

RCA connectors are readily available, inexpensive, and work quite well.

I don't know why hams are "stuck" on the inferior PL-259
plug and SO-239 socket. Well, I do. It's because manufacturers
keep sticking them on the back of radios and we don't insist
that they stop using them. For a small connector, I would
prefer SMA. BNC is "OK" but the bayonets wear out if you
you connect/disconnect them enough times. For a "large"
connector, the N connector is superior in so many ways.
