If you have adjusted the bias then GATE cannot be 0V. Check voltage on R97 and 98 both sides of the resistors and see what youget. When KEY down the TX has RF in CW mode and readings will go haywire.

Anyone?

Did you changed the setting of those "Blue" pots RV2 & RV3 after changing the IRF510. Even if you have no worries you could have reduced the gate voltage (remember turning those pots clockwise reduces

opps (sorry, hit enter too soon) q94 D 15/15/7+- G 0/0/-.09 S 0/0/0 q95 D 15/15/7->8+- G 0/0/-.10 S 0/0/0 With key down, the Gates move around a bit. Thanks so much for all help here!!!!!!

Thank you!!!! For a Liberal Arts major, that means a lot!!!! I tested U2 and it toggles between 0 and +5 on RX to TX. And the bias was set at ~100ma per 510. I did more tests on the IRFs using +15v

Don, you did a good job. I won't worry about Q90 as you must have seen the document says not to worry about small variation. But I find it unusual that you don't see any Gate voltage for Q94/95 it

Evan, Raj, Jerry, + Co. I feel like I just finished Lab Class for Electronics 101. My lab notes are attached for credit. All the transistors measured with V+12.01 in TX mode w/no modulation and no

Hi, I haven’t found calibration instructions. Assembly, circuit descriptions (which are fantastic by the way), yes…but somehow I’ve missed the calibration instructions. Buddy Brannan, KB5ELV

Did you have to re-design the Radiuno connector locations to fit the new display? -- Dale Hardin, KS4NS Elberta, AL

We have left the old traces, connectors etc in exactly the same place. The software is backwards compatible with the previous versions. If your board has 12 mhz, you have to just edit that one line to

It’s sold.

I think there is an option in the CEC Memory Manager to direct which should be displayed Rx or Tx.

Thanks!

Interesting topic. I guess I'm just more accustomed to having the rig display the TX freq and shift the RX to make it audible. But in uBITX CWU and CWL the display is the RX freq with the TX freq

Aargh. I may be wrong here! If I am, my apologies, it makes my head spin a bit. I’ll have to go fiddle with the radio and try it out.

I’ll have to look back at the code to see how the MicroBitx works, But after dealing with this at last field day, I wrote a document on how my ICOM works. It may not be quite what you

Hi, I have always preferred my dial to show my my TX carrier frequency whether or not it is suppressed. There are fiducial marks to show where to set for receive (USB or LSB). WWV is double sideband,

Hello all, I've got two unbuilt/unattempted kits for sale. Both kits are as packed by HFSIGNALS. First up, an unbuilt Bitx40 from Dec. 2016, 2x speakers and an undrilled case from Amazon (blue &

What I think he meant, and what I was wondering, is whether you added any new thru-holes for easier imstallation of some common mods. Specifically, the tx/rx LEDs that came with the custom case kit,
