With a 2.4khz to 2.5khz filter you wouldn't want to run the tones any lower than about 1.25khz so you could filter out any audio harmonics, right? My guess is that if you are generating audio

Using FLDIGI, you can put your RTTY tonesanywhere you want them..... And by watching the waterfall, you can visualize your receiving filter as well. gordon ________________________________________

There is plenty of overlap in the inductance rank now. The final kit will probably be closer to doubling. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner - Operator

Jim, Aren't RTTY tones 2125hz and 2295hz? The filter in the ubitx should be narrow enough to filter out 2nd and 3rd harmonics of these frequencies. If it can't filter out the harmonics of these tones

I've been lobbying for an afternoon time for months now. A few of us got on at 3PM EST a month or so ago and made a number of contacts. So if anyone can agree on a betting time I'm in.? -- John -

This is kinda normal....the critical frequency (vertical 180 degree refraction) is dropping to 80 meters or BELOW right after dark over a lot of North America....traffic hounds in the north are having

noticed same thing here up north since last fall. After grey line NOTHING! Local path only. I suggest earlier times - 4pm EDT - 2100 Z perhaps. Real hit and miss an evening net this time of year and

?Ah! From your QRZ page you have an ICOM 718 exactly like me. One additional question: are you able to make small changes in the code of the firmware that you've downloaded? like minor edits? And

?Can you give a little more information? How far off? Exactly how did you measure? What did you do (give the details) when you tried "calibrating"?? Do you have accesss to an accurate existing

Jack you are right. I was thinking of this ubitx software center git. Ron To: [email protected] Sent: Sunday, January 7, 2018 10:20 PM Subject: Re: [BITX20] Tuning reversed issue Sounds like more work

Sounds like more work to me. There's nothing sacrosanct about the two analog pins. As far as changing sketches, whose sketches? If you write your own, it really doesn't matter. If you use someone

Even easier is using a small object (thumb tack, tiny drill bit, etc) to unhook the black and brown wires from the header and reverse their positions. Then you can change sketches without worry in the

Hi Bill, Great project. Very interested in this as a remote tuner.? One query - why are the last two 5.2uH and 10.6uH as opposed to continuing to double up? Not a criticism just seeking to

Need some advice on how to calibrate my ubitx. I have read the instructions. ?After several tries no success. Reloaded the firmware but freq is still off. Is there a better way to calibrate? Art-

So for all the folks that sent me emails about the cheap auto tuner kit... i made some progress this week. The cores came in and i would a staggered set that total 20 uh. All checked out and tested.

I watched the band go dead after it got dark here.

The cases you see are for the bitx40. They will have a ubitx case, shortly. It has not been released for sale, yet. It is supposed to be released sometime his month. Marco - KG5PRT

I’m considering ordering this great looking all band semi kit. I’ve built s number of kits of varying levels of difficulty. I noticed that there are some cases for sale on eBay but it’s unclear
