Albert, Karl: Consider this error in your listing: /Users/albertdunk/Desktop/ubitx4-master/ubitx_v4.3_code/ubitx_v4.3_code.ino:637:26: warning: deprecated conversion from string constant to 'char*'

Thanks!!

Giles Price is right. Size is right. Could be an interesting part of a lab-grade analyzer. Arv _._ wrote:

Good afternoon Karl, Thank for replying, The only port I see in the list is ?/dev/cu.Bluetooth-incoming-Port. Best regards, Albert VE3TYS

Great news Frank, glad it all worked out for you. Joel N6ALT

Yes, you can install?the Arduino IDE on a Pi. See here for instructions (they are 9 months old, so some version numbers may be out of date, but in general it should work):

Yes, I meant spectrum analyzer. And definitely would have the tracking generator, trivial now with multichannel signal generators like the si5351. Though I've been thinking would be nice to include a

Joel, Just wanted to thank you again for the advice. I went ahead and uploaded the KD8CEC 1.08 firmware to the rig, then successfully calibrated the uBitx. I was able to make a QSO with a station on

Hi Allison, I need a little help with this! I dragged all the files into the root folder and I see all the tabs now, so just upload and see what happens right?

Correction...the pre-scaler is a 74HC4060.

Some time ago a person asked if 50V capacitors would work in outboard LPF designs, and I forgot to answer him. Yes, those 50V capacitors should work for QRP, but not for higher power. If 100V caps are

Add a monchrome graphic display and you have a spectrum analyser!? A 128 or 240x64 will do fine some need I2C other can be run with 4bit interface like the 1x16, 2x16 and 4x20 displays. or just get a

You might get by with 50v caps at 10W max, but that's marginal. Much better would be 100v, likely sufficient if scrounging about in the junkbox. I'd go with 200v if ordering parts specific for this.
