Re: ubitx example of enclosure
I purchased an assortment of Christmas tin gift boxes in a variety of sizes at Dollar Tree, Walgreen's, and Hobby Lobby. Most for $1 and all for under $3. Check out your local after Christmas sales. My uBitx and Bitx40 will be festive all year long.

Adafruit has RG-174 in 3m lengths. I'll be ordering some soon.

Re: OOPS!! Re-factory alignment....
Ground loops are a major pain in the *^{%. Connecting to computers only adds more parallel paths to make loops. I¡¯m running into problems measuring current draw from my DC supply because Power is finding alternate paths back to my supply than through the negative Power lead; apparently my meter measures on the negative lead, not the positive lead. This is most pronounced in my car.?

"right on frequency".? ?
Approximate settings that might help someone with even less test equipment than *I* have were the following:
1st setting:? 10.000 MHz adjustment was on target at? "15"
2nd setting:? my best guess at when the 7.150 MHz LSB signal (generated by a vacuum tube radio driven by another raduino) was when the last digits were 96.7
At that point I was able to hit other WINLINK servers on 40 meters with less than 10 Hz apparent error.? ?(you only have to be within 200 Hz).? ?
However, it took 3 tries to get to there, as the first go-round was more like 50 Hz off on 40 and twice that on 20m.
I was a bit "agitated" and in a hurry so I haven't studied Ashhar's routines and don't fully understand the purpose of each of his tests.? ?(A "manual" for factory alignment would be wonderful....)? ? Others may do a far better job explaining all this.?
?I haven't yet gotten the bravery to upload a sketch to this wonderful machine yet, as I have for the bitx40.? ?A brief listen to the 25 MHz oscillator (without driving the output freq to that, which would have made the signal a LOT stronger) --- it does seem
to be about 4kHz high as we noted on bitx40 raduinos.? ?
Hope this helps any other hapless people.....

Just finished building a Kits And Parts () SWR bridge.? Says it's good for up to 100W intermittently.? Probably would accept the 10W from the uBitx w/o a problem.? Designed to output to a pair of current meters, it could be hooked up to analog inputs on the Raduino to read forward and reflected power.

If any of you have access to a laser cutter, or are really handy with a fret saw, you may find this useful.

Re: Power output decreases as a function of frequency?
#bitx40
Raj,
Could you suggest a method for bypassing L1-L3? I'm not sure how I would do that with any temporary change, any approach I can think of would be permanent and then attempting to reverse the damage later.
And where is the output filter on the board?
Something is definitely off center, I set the Raduino to transmit out of band and the power tails off in a rather symmetrical pattern centered on 7000khz, with another attachment showing the output power vs frequency.
Thanks!

I have one board with the filter centered a bit and gives less power higher up the band
but we work only till 7.2MHz.
It could be the output filter also.

Bottom line up front:
I am having a problem with my Bitx40 where the power output decreases as I increase my frequency across the 40m band.
I completed all of Allard's 1.27.3 mods, plus RX/TX lights, and the spurious emissions capacitor, with it transmitting through a SWR meter into a 50W/3.5ghz dummy load. Power is from a variable power supply set to 12.0V, which includes powering the PA.
I'm receiving the following readings from the SWR's forward power gauge and the power supply's current meter as a function of the tuned frequency when using my straight key for ~1 second:
Frequency, SWR meter forward power, power supply current;
7005khz, 4.5W, 1.15A;

Cleaning up digital signal while using CAT
Hi,? noticed today while using Ashhar's CAT routines (FT-857 & similar emulation seems to work fine) -- that my transmitted winlink digital signals were.....lousy.? ? ?
When I added some clip on ferrites to the usb line driving the raduino.....the signal magically returned to wonderful sounding WINMOR.? ? I put on two clip ons.? ?
If you use digital signals while controlling the Raduino.....ALE, WINLINK, FLDIGI, FT8, whatever --- you might want to add ferrites to the usb line to the Raduino.?
And I also copied wonderful JT9 with the uBitx today; possibly due to not knowing the above, wasn't able to make any connections, but I'm sure that will come.??
