Thankyou. I agree. The radio should be heard farther, it isn't a dancing appliance. -- Michael Shreeve N6GRG

Dynamic Mics are Great for music and performance. ?After all for speech communications limited to just 1.5? to 2.8KHz bandwidth, perhaps? any mic would suffice. we don't get FM quality or DRM

I've been sitting here on the sidelines for a while. I was hoping to have a complete solution finished by now. However, life gets in the way. I unexpectedly got 2 consulting jobs, plus my teaching job

Ed I am thinking the stock firmware is not a significant factor in CW operating.? I would suggest using a CW audio filter with the uBITX.? One candidate is the hypermite from 4stateQRP - there is at

If those issues were solved, I'm sorry I missed it.? I've seen others with the same issues.? In any case I'm glad you are going to give it a real shakedown on CW.? Please report the results of your

i have a uBitx that I want to use primarily for SOTA using a straight key and the stock 2-line display. Of all of the firmware options, which one should I?install for 2-line display and straight key

thats my take on the uBitx ...Simple ie cheap parts ..Easy to work on ..Its all right on top ..spread out with BIG surface mount parts ... Play to your hearts content Jim

I’ve taken a look at this circuit, too. I think Sunil is talking about the power to the first bi-directional amplifier (receive +) before the mixer. I don’t know how well that would work, but I

Thank you for the thoughtful responses!? Great ideas to digest.? I have the Solid State Design book but have not worked my way through it.? May be that is homework :-)? The explanation at the

I find clarity and precision of instructions--if any--sadly lacking from many electronic kits and projects.? The same goes for illustrations that lack important details such as part locations,

Hi everyone. I’m up and running and the radio sounds good! I went in and did a Set Calibration and then Set BFO and all is good. Boy you can really get this thing out of whack if you’re not

Anyone of you having TFT file for 3.2 inch basic display? The one which is in a zip package is too small, loads ok but looks strange in the upper right corner...and my fingers are way too thick to

Couldn't get it even in as the display says it is not for this 3.2 standard. How can this be so damn difficult?... Kai OH3WE

Hi guys, can't see any NOT ENHANCED tft file for 3.2 in screen which I use in my radio. Tried 32E_F_0_2d.tft but no go... Or do I just miss something? 73 Kai OH3WE

I was only citing K2 as example, yes now unobtainable or costly parts as I alluded to. Some of its circuits, like the uBITX, have legacy to discussion in those 2 W7ZOI et al books. The older one has

I just got done posting a couple of medium resolution videos of our 2.8" color display (touch screen) but with a "non-touch" feature, control by wired or wireless MOUSE. The videos are not

I also too have the K2 manual for my unit ...Looking a "little further in front" you will notice 5 ea. band-pass filters ...Not dc to daylight transmit path ... if you want K2 performance, buy a K2 @

Hello again to all HAM, I should ask again because the Ubitx doesn't receive like it should, till till today..nothing has found but this should not right when see the?*Ubitx v3 (FCI)?* first batch
