good evening I have a problem with a BITX40 that never worked! I replaced the motherboard because I thought the problem was there. It is not so! Only the raduino remains! I wrote an email to

Mike, Now THAT spec from Farnell was what I was looking for.? The 151 pages have a lot of good RF information not found elsewhere.....but will take a little time to digest. 73 Kees K5BCQ

The original on the my test board toroid inductance was `560nH and I added another 2 turns.. to make it nearer to 720nH as stated. not helped! Shielding did not help.

Did anyone check whether there is any difference in the attenuation with the different Axicom relays? What I mean is that according to some posts it appears that the relays have different

Raj seeing that you used a lower inductance, could it be that there is too much inductance in the Toroid ones? Did or could you experiment with other values? Could you try to lower the originalTtoroid

Farewell Farnell!

After all seller groups would make use of any sudden spurt in demand of a product. After ham community identified the use and benefits of axicom relays, the sellers would obviously raise the costs.

Hello Mike Thank you very much for the work you do for ubitx.net. This site is really a mine of information for all those who have embarked on the adventure ubitx. Gilles - F1BFU /FR

One of them must be on this group! Raj

Interesting...... the price for V23105A5403A201 relays from Farnell in VK was AU$2.28 a few days ago. Its now $3.97 glenn vk3pe

Mike I suspect that the bracketed phrase (current tested) in the datasheet may be to the relevant clue for this relay (5476). Presumably they are tested to meet the 3A switching capacity. All of the

Embarrassed to ask, but... I've just tried for the first time to upgrade my uBITX software to the current KD8CEC release and must have missed something obvious. After unzipping the files, I compiled

Kees, Since I started this, let me jump in here for a minute.? My intention in starting this thread was simply to provide information on favorable results that I had.? I appreciate that Jim jumped

Thanks Dave It's been more work than I imagined, but it is a pleasure to see so many constructors having fun and extending the functionality of the uBITx. 73 Mike ZL1AXG -- Mike Woods

I think the 1210 shielded one would be best! Raj

I did that and it did not help much! Raj

I ordered a sample book from China.. good for experiments. Raj

Only way you'll get any more than what's in the data sheet is contact the manufacturer. Anything else beyond what's in the spec sheet just guessing without answers from them and I don't have contact

Here's the simple calculator I've been using.?? http://66pacific.com/calculators/toroid-coil-winding-calculator.aspx
