Very good Dan great catch on forty. I’ll be trying to get mine on tonight.

Re: show your mic

Gary Anderson
 

In the spirit of fun, here's mine.  I can honestly say, I've never seen one like it. Made from three discarded Copenhagen cans, a junk box metric-pitch tactile switch, the supplied mic, a TRS socket, a thin piece of open cell foam in front of the mic, a thick piece of close cell foam surrounding and behind the mic, and one pop rivet to hold the PTT lever.  The mic is mounted on a circular plastic disk slightly smaller the the ID of the can which was cut from the third can and drilled to locate the mic. The PTT lever (cut with aviation snips)  works surprisingly well, and the mic is comfortable in the hand.  The socket allows the cord to be swapped out and possibly a stand in the future, where the mic can be held by a male plug. As far as sound quality, don't know yet.

The thing in the instructions that many people miss is the last instruction which says push PTT to store and complete.  I  didn't see that at first.

I am confused wiring to the jacks. The standard jack terminal no.s do not seem to apply to the wiring pictorial.
Do I go by the jack terminal no.s or the way the wires are connected in the pictures? With the terminal side up and the plug
opening to the left, my reference says the terminal no.s are:     1 -terminal closest to opening, 2 single middle upper terminal, 3 back upper terminal,4 lower back terminal, 5 mid inside just next to 4. From the wiring pictorial it does make sense. Thank you in advance. 73 Mike KF6KXG

Re: Low mic gain, was, show your mic

_Dave_ K0MBT
 

My bitx40 really improved when I put a replacement mic in it. One day I was not getting any signal out of the transmitter. Tracked it back to the mic which was dead. Originally it worked for a month. The replacement seems stronger. 

Re: Erratic tuning with my new uBitx

Nikos SV1IYF
 

Hi Chris,

It surely sounds like a frequency calibration problem, but it is also uncertain as to which piece of equipment contributes more to the error, i.e. the μBITX or your frequency counter,.
Unless your frequency counter has a high precision reference like a GPS disciplined time base, or at least, a TCXO of recent vintage (crystals age), my suspicions would fall on them both.

What I would do:

1) Use the calibration tool of WSJT-x to check my μBITX against a frequency/time standard station at the highest frequency I could get a clean signal from (14.996 MHz here from the Russian station). Note down the offset.

2) Do the same as in 1), but this time using my other rig in TX mode as a frequency generator and adjusting the dial frequency as to get the same offset as in 1).

3) The scope of  step 2) is to establish a local frequency source of suitable power to be measured by the frequency counter, thing to be done here.

4) By now I would have 3 numbers:

a) The dial frequency of μBITX

b) The offset of WSJT-x calibration tool

c) The indication of the frequency counter

Enough information to allocate both (?) frequency offsets.

Rectifier fuse crowbar. #ubitx

Lee
 

I am using 2 fuses. One for the output transistors and one for everything else.  I was thinking of using one 6 amp rectifier that points in the direction of the power switch and then a wire from the power switch back to power each fuse.  It won't crowbar the fuse with wrong polarity but just stop current flow.  Voltage drop should be around .5 to .7 volts.  I could always parallel 2 of them to cut the voltage drop to 1/2.  What do you think?

The band seems to be pretty good right now, but I couldn't make anyone out on 7277.  I called on 7277 and 7177 several times, both at 7:20 PM ET and at 7:35 PM ET.

Heard Glen KE0NXP talking with WA4THR, both were 5x7. I think I heard VE3THR, but kinda down in the mud.

I didn't jump in because my BITX is in pieces on the bench.

The only station i could really hear well tonight was Tom. I could hear some of the other stations on and off but I had an S9 noise level here tonight. Was using the FT-891 again tonight running 10 watts. Hopefully I'll get the BitX-40 back on the air by next weekend.

uBitx Relay K3 Pins 1 and 5 Location

Can anyone provide a picture on the location of K3 pins 1 and 5 on the circuit board? The schematic pin numbers do not match the manufacturers data sheet.

Take a look at the attached pic.  I had the same issue on my BITX40.

Fought through the noise and made one QSO with VE3THR Tom.   That's 2 weeks in a row.

Hi Jim, 

what are your thoughts on doing the same with the Raspberry Pi Zero boards? in some areas such as my own they can be purchased for as little as $5 USD. 

-Justin N2TOH

P.S. I should find the most effective place to ask about an Arduino IDE add on for the Pi boards so they might function as an Arduino alike board.

I was mobile in Northern Virginia and worked a bitx station in Missouri at about 7pm but there was strong qsb as he was very strong then quickly went down to barely readable.

The diodes in parallel will up the current capacity but volt drop won't change much. Using schottky diodes will give the lower voltage drop you need.

Re: Teensy 3.5/3.6 upgrade for uBITX

Jim Sheldon
 

I don't really have a clue regarding the Pi Zero.  I do know the Pi Zero is faster, with a bit more RAM.  I don't think it would easily replace a NANO, and wouldn't interface easily to the uBITX.  Not saying it can't be done, but someone other than our group will have to be the guinea pigs on that one LOL.
