So, exactly what math is this that was shown? Perhaps post 44560? Michael is only describing the conversion from 1'st IF to 2'ed IF, he's quite aware the uBitx is double conversion. Take a look at

DHL package showed up. Didn't open it up to inspect tda chip. Will post when I find out. Cory N7FV

Just ordered ten RD15HFV1’s from RF Parts. Considering how SLOOOOOWWWW their site is there must be a run on the RD’s ;-) . Mike K5ESS Sent: Wednesday, March 14, 2018 3:30 PM To:

Got it backward and could not go back and edit.? should be... ?The trick is if you take 45-33 your get 12?(the minus means inversion in frequency in this case) or its ?45-57 or -12 note the sign

From what I read its not a bitx20 or 40, so the math shown appleis to a single conversioon receiver. The microbitx ubitx is very different as its DUAL CONVERSION. So any math shown is just plain wrong

HI Farhan. Does this mean V2 uBitx will have RD16HHF1 ??!?! LOl, thanks, 73.

Plenty of errors to be found in comments and documentation, including mine. Better off obsessing with how it works than what the documentation says. Been there for awhile. I doubt it's "trivial". And

There are two tiny metal "tabs" or fingers in the arduino-nano mini-USB socket that can get hooked into the plug when it is first inserted (has happened to two different Chinese made nanos in our

Yes, his numbers are off. Filter passband on the Bitx40 is around 2000 hz wide, 3 dB passband might be 11996000 to 11998000, within a khz or so, depending on which bin the crystals for his rig were

Well, wrong or right isn't what I'm looking for, but the basic detail I was interested in here:? Likewise, a high side clk1 of 56995000 hz? for USB always flips the sidebands when translating to

Rod, Do your headphones have a stereo/mono switch? If so just unwire the speaker lead going to the ring contact on the audio jack and set your headphones to mono. That's what I am doing (actually I

I'm not sure what your frequencies mean. 11994420 - 11984800 = 12000 and 11996450-11984800 = 9620. These don't match your 2030hz and 4060hz figures. If your crystals all average out to about

Of all of those links, only the last one is any good. All of the others do not have a threaded shaft, which most people will want. I've probably purchased 50 KY-40 encoders and all have worked well. I

Nice! Where did you get the plug/adapter?

I've looked at encoders which I believe are used in the uBITX .? Perhaps you need one, they can be blown up with incorrect hookups, or physically just bad. Or perhaps your doing a special project and

Besides it's hard to go wrong with the author of the book a big supporter of the forum. Leonard kc0wox

I didn't notice it too much myself until someone pointed it out.? Now it drives me crazy.? Was thinking if I am going to build an audio filter I might as well socket the MX TDA2822 and mount the IC

Either is probably good enough. Both is best. We don't really know much about the WX except that many have blown in the uBitx. I'd tend to replace the chip. There are reports on the web that some of
