 Mine should be here Monday or Tuesday and I got absolutely no notices from PayPal. I only was able to follow with DHL tracking.
 I believe you have the Customs tax with DHL backwards. No cost in the United States but there is cost in Europe and that's why most Europeans are using India post.

I assume your PayPal notification is for the payment. PayPal will send another when HF Signals inform them the item has been shipped and that second message should mean it's on it's way. As you can see it took another 10 days to arrive here via India Post and Royal Mail with no further tracking once it was 'in the bag'. I got the Jan 24 message from HF Signals following an enquiry, so I might not have heard anything until the second PayPal message. However, as Chris Gress says, I think they have stock of Bitx40 and if so yours could be shipped quite soon. And arrive even sooner if you use DHL, but I get the impression if you are using DHL in NA they will slap a tax on you. Not sure if that happens UK so I didn't take the chance!!

Strong carrier on transmit. #bitx40help

radioant@...
 

I set up my bitx40 for transmit and on key up I heard a strong carrier from the bitx40. The carrier was 20 over on monitor receiver.  No it wasn't feed back from the mic. I looked at the balanced modulator circuit on the board and discovered that D15 and D16 and the 100 ohm trim pot we're not in the circuit. But a dual diode D20 was there. Could someone explain this modification and if anyone else has had this problem. Will see if any DC is getting back into modulator.  Thank you Bob WB2TFG

Re: Strong carrier on transmit. #bitx40help

Vince Vielhaber
 

It was a change HF Signals made about a year ago and has worked fine. The dual diode is better balanced than you would get via the pot.

Did you do any of the mods to the board, like perhaps the one that involves a 10K resistor to the area of the balanced modulator for CW?

Vince.

Re: Strong carrier on transmit. #bitx40help

Dale Brooks KG7SSB <kg7ssb@...>
 

Hi Bob, the diode package you are talking about was substituted for the 2 diodes and pot with the thought that the packaged diodes were a very good match and the pot was not necessary. My BITX40 came the same way and I haven't had any issues with a strong carrier. I have built this circuit on a home brew rig and used two individual diodes and pot with better results than the BITX without the pot adjustment. But, you shouldn't be getting a strong signal on the output without audio. If you have a scope check the mic audio amp circuit and make sure that there is no oscillations with the mic disconnected. You can also check the input to the diode package legs(D20) and see that you are getting equal signal on both diodes. It's possible that one of the wires on the transformer is not making a good contact on the board. It will be a 12mhz signal from the carrier oscillator input. 
I'm sure others will have more ideas and tests you can perform to isolate this problem. Good Luck and let us know what's happening. Dale kg7ssb

Blown by nearby transceiver #bitx40help

edufortes@...
 

After doing some tests with the rig, I made the mistake of transmitting near the Bitx40 with an ICOM 725 with a badly isolated tuner,
 
A quick flash, smoke, and the bitx40 that was only on, no antenna connected, died. No more tranmission or power output.
 
What components should I start checking or replacing?

Eduardo

Hi Chris,


HFSignals Team replied to my enquiry in 3 hours.


"Yes, We have received your payment of USD 59. 

The order will be shipped in 3-4 days. 

Tracking details will be updated once the shipment is done."


Sounds like they have it in stock.


Do you know how deep a box I need for the BITX40 with Raduino? 


I'm planning to repurpose my flaky IC-25/AE (5"x5"x2") for it.

Re: uBITX woes, feeling disheartened. #ubitx

 

Sorry all the voltages you mention are wrong!

Pin 5 & 8 MUST have 12v if your board is connected to power supply 12v. No 12v means RX will not work..

Pin no 1 (Square pad) can have 12v ONLY on TX.

I suspect that you are not measuring properly or counting the pins wrong... cant be this way off.

Hello all! I received my bitx40 last wednesday (total newcomer).
Thanks Jerry! I had the issue of the broadcast station at los volume setting but after soldering a 10nF capacitor between cursor and ground of the volume potentiometer, the station dissapeared! 😁
Thanks for the advice!

I just measured a board. It's 4.9" x 4.7 x 1.1. You can shrink the 4.7 down to 4.5 with a different heat sink. It'll be a tight fit.

Re: Fast tuning buttons

Jack Purdum
 

Fast Tune works by observing the rate at which the user is turning the encoder. The timing and tuning rates are set with #define starting around line 64 of the attached files. For me, if the encoding is pulsing faster than once per 100ms, I'm doing a Fast Tune. Slower than that and I'm just tuning around. Read the code in loop() to figure out how to use it. You will need to put both files in your project subdirectory.
