The Si5351 can easily send rtty. see the cw code of ubitx. you have to just push the clock to a different frequency. - f

did you use the settings menu to lower the bottom frequency allowed? ________________________________ Sent: Monday, January 8, 2018 8:02 AM To: [email protected] Subject: Re: [BITX20] uBitx 472kHz? I

If you have a ubitx, then ALL the frequencies are derived from the si5351... So how do you know it is "off"?? Can you send an AM carrier into an antenna with your 7200 and find the signal with a 6"

I tested mine and I cant even tune my receiver under 1 Mhz?? How to listen under 1Mhz?? Kari

Kari, I was able to hear a local beacon on 398khz so it at least receives this low.? If it transmits I expect it will need a LPF for this band as the onboard LPFs will be insufficient. Regards Simon

The si5351bx routines used in Allards code and in the uBitx already do bulk transfers: See post?/g/BITX20/message/34362 Though doing FSK by i2c writes to the Si5351 will make for

Hi All Here is the first step in my free uBitx development enclosure, holes for controls to follow..... ...yes the plastic box it came in. Be careful when you cut the holes! 73 Mike G0CVZ

Gordon Tuned to 10mhz. Selected calibrate in setup and zero beat per instructions. I am close but think it could be tweaked a bit more. I have a icom 7200 - need to update qrz profile I reloaded Ver 2

Hi All, It appears ham rtty speed fsk is quite feasible on SI5351. Looking at https://github.com/etherkit/Si5351Arduino/issues/22 especially the paragraph that says /"Additional comment which solved

Hi All, See below from W0EB: I have not yet done the digging, but if the si5351 is like the si570 then I believe hardware fsk is quite possible, with no ubitx hardware changes. Just use the key input

Hi Bill, I am very interested in your affordable autotuner. I must have missed the beginning of this thread. Would you please be so kind as to let me know the link to the details. Thank you. Best

@Vince - OK well at least it's not just me then. Bit of a shame but not that surprised, it was exceptionally cheap. @Arv - Yes don't see why this isn't possible. I've not seen any work done on this in

Hi all I am new to this group and just got uBitx from the custom...only 22% VAT was added I am wondering if uBitx? can somehow work on 472kHz amateur band? Kari OH5YW

The Red LED on the Arduino board is on solid.

Followup on the Builders Fest in East TN, it was great, ask Dr. Jack, he packed the house with Bitx enthusiasts. And the hamfest with its indoor arena tailgating was at capacity for the first time

let me be the first to say...you are mistaken.? I am interested. ?I would surely be safe to say there are others.... I invited BitXes to East Tennessee, USA ?just yesterday, and I very badly wanted

This is probably not of universal interest to the group... My club, the Lamakaan Amateur Radio Club is organizing the LARC'18 on January 26th and 27th. On the 27th afternoon, we are organizing a group

Jack, Thank you for the draft copy of the chapter from your book!? I put the book on my wife's Amazon wish list and told her I would really love it for my birthday this month.... Crossing my

If you're having problems with audio harmonics, yes, you would want to put your tones higher than the midpoint of the filter....but with any reasonable sound card, there should be negligible
