Better Schematic


 

Where can I download a better Schematic of the UBITX?? I cannot read the one off the website the resolution is low.

I need the resistor values for R63 and R60.? I did the dynamic mic mod and may have to replace these resistors if I cannot get my dynamic mic to work with the UBITX.? I need these values to order some SMD's

Does anyone know where to buy a package of SMD resistors with many different values?

Thanks for your help

Hi Walter,

There is a clear schematic at the following location (found on the hfsignals site):



This is for version 3 of the UBITX.

As for getting a selection of SMD resistors I would suggest getting a mixed pack from somewhere like Banggood:



I have bought several of these small kits in the past and they are a great way to instantly (after shipping of course) get a wide range of resistor values.

I hope this helps,

Kerr

Outstanding Schematic and SMD source.? What value SMD's do you think these are? I see 0603,0805, 1206.? What is the standard size using for electronic projects like these?

Thanks for your help

The uBitx surface mount R's and C's are all in the 1206 package.
The surface mount 2n3904's are are mmbt3904's.
The audio amp is the TDA2822M variant (M says it's in the 8 pin DIP package).
