Re: Schematic Drawing Software
Linear Technologies LTspice is a free, powerful and versatile
program. You can easily draw excellent schematics and print them
or email them. Many of the schematics you have seen on this
reflector have been drawn in LTspice.

Hello All,
I have a software called Auto Sketch that I try to draw schematics
with, but it did not come with a symbol library.
obviously, for a hobby I won't spend $2,000 or more for Cad.? What
are you folks using to draw your schematics?

Re: Erratic Tuning bitx40!
I had this problem one time and it was the 100k tune pot opened. Just before failure the pot tuning was unstable. and noticed the wiper action was getting rough.? I was using a cheaper blue Chinese pot at that time.

One thing I have also noticed is that when first turning the radio on, the Radino with version number displays, it never used to? So I’m wondering if something has reset? Any ideas please??
Many thanks Carl M0CLS?

We are continously producing now, however, we are not able to meet the demand. Hence, the backlog still remains. I am hopeful that into early march, we will get past the backlog and start shipping ex-stock.?
I am not very active on the mailing list these days because I am heads down, making test jibs, documenting the test procedures, writing arduino code to automate as much as we can. I hope to wrap it up and get back to homebrewing by the end of this week after handing over these jigs and software to the HF signals folks. Some of this stuff is quite neat and of interest to regular builders as well. i will post these circuits and code shortly.

Re: uBITX without Raduino
Not very different.? My uBitx Raduino is different than my Bitx40 Raduino in the following ways:
? ? Has uBitx firmware pre-loaded (but you can load any firmware you want through the Arduino IDE)
? ? Has the LCD contrast pot mounted opposite where the LCD plugs in, so you can easily adjust it
? ??The 16 pin P3 connector has a 16 pin right angle header installed, not a 5 pin KF2510 type connector
Perhaps there are other changes, but I doubt they are of much consequence.
Schematics for Bitx40 and uBitx Raduinos appear to be identical.?
So either rig could use the other's Raduino, just reprogram the firmware and deal with P3.
The resourceful amateur should have no trouble either replacing the P3 connector or adapting the cables.

Re: #ubitx replaced Arduino Nano gives a lot of I2C interference during reception
#ubitx
? Not that it helps considering the disposable nature of the Nano.? But my guess is bypass capacitor issues on the Nano.? I guess if some determined soul wanted to verify they could attach a cap in parallel or swap out the bypass caps to see.?? Again seeing the cost it would be more of an educational adventure.?

Re: Variable power control
Here is a pot controled version of my original zener power control. since i am an anti-rail go i added high limit and lo limit resistors.? when i was young i persued a second class commercial operators license. in the log everyday the on air guy had to write down plate voltage and current. those 2 multiplie provided the FCC required station wattage. that was at the transmitter? so swr, connector, and line loss were not factored. P=I x E. this was not the RF OUT or the effective radiated power.?  ? i will be adding a simple accuate circuit add on to this to report voltage and current supplied to the output stage using 2 analog inputs to my system health display. dave N4LKN

The G6LBQ multi-band Bitx uses the MC1350P, but the input and output impedances are different. I read a post about it has other problems, too. I don’t think anyone has posted a fix, however. I’ve even looked on the data sheet to see if the impedance was listed, but I didn’t see anything.

Re: More pins for the Raduino! An RF gain control for the uBITX!
It's workable, (lotsa work though!), but at that stage, the area of the thing becomes antenna-like. I can remember my elmer, (RIP Walt), demonstrating how a shielded air-cooled dummy load could be heard for a block with a portable transceiver. It was very directional, but still...

You might search the archives for this discussion.
I have already built and tried the W7ZOI AGC. ?It works ok in the UBITx with the replacement the first IF amp with a dual gate FET...second gate used for AGC voltage. ?Ive now abandoned that work because its way too complicated for this simple radio... and instead using the AD8361 RMS detector and LP filter and the AD8367 variable amp/ attenuator. All that is required is the addition of an integrator, easily supplied by an OP amp (additional op amp on part used for S-meter by amplifying AGC voltage). This circuit is about the size of a coin and works ?exceedingly well.?

Re: uBITX without Raduino
I don’t think you’re going to be able to buy that part by itself for quite a while. Multiple people here including myself have built circuitboard to allow making their own. ? Best move would be to use one of their offerings.

Anyone have contact information. To obtain an answer and complete my purchase as needed.
