I'll take the DSP filter. -- 73, Yvon NU6I

Go to the DHL website, they have a mechanism for dealing with that problem. Clark Martin KK6ISP

Hi Hank, Was just getting ready to email you when this came in. You are still in the queue for one with the SMD semiconductors installed. I ran out of the 5 volt regulators because my last order

I will be gone for an extended time when my DHL ubitx arrives. If a signature is required does anyone have a suggestion to get my hands on it. Neighbors are too remote. Bill

Have you sent out email to the lucky ones? I haven't seen anything from you so assume I was too late. Hank W6IR

Nice looking rig AA7GW

Is shielding not usually needed for these radios? Or are you using some metal-bearing plastic that blocks some RF?

I too had the now famous R141 getting smokin' hot. At the suggestion of forum members, I replaced Q14 with no success. I read and re-read voltages as well as component values in and around the

Here is mine in the Hammond 1402DV (V for Vented since the heat sinks are inside.) ?It's tight with the Volume Control mounted in between the display and the extrusion. So the PCB is mounted as

Hi to all. The flowchat is a instructive guide for the curious of how to doit without float point math and an expression of the KISS principle. It's just a cheat sheet to learn from. The trick is

Funny as hell ?!! But a good, solution. KC9SGV

I can use everything except the DSP filter if still available. Steve, N2FT

I would like to buy your uBitx. Please send remittance details. Bob N1ETS

Yup, not much point in getting too carried away in creating a VFO for the Bitx40. Initial accuracy of the si5351bx routines can be calibrated to be quite good by adjusting si5351bx_vcoa But a slight

Try “mu metal” shielding found on Amazon AA7GW

That should read ‘rewiring’ Not rewriting!

If the math/hardware has a better accuracy than the Xtal itself then you have at the output just the stability of the Xtal... right? 73 Pavel CO7WT

Michael The uBITx and the BITx40 have different circuitry. In particular the uBITx has 2 IF stages (45MHz and 12MHz) whereas the BITx40 only has one at 12 MHz. Some changes would be required to the

Calculations within the si5351bx routines are much better than than 1ppm accurate, perhaps more like 0.01ppm. As I recall, the math was accurate within 0.2hz when doing calculations for a high side

Good point, if we're worried about magnetic field coupling then tinfoil won't do much good. I'm not sure exactly how the power to blow 1/4 Watt resistors would be communicated, was guessing it might
