Hi, This is normal, when both of them have has used the same arduino pins: A4 and A5. Need short cables, and also You might to use SPI interface for display and I2C for Si5351.(It's easy to convert

Yes, as per my first (top) post - late on 13th Dec 2017 Nigel

I ordered mine december 12th. I received it as 009/2 in France on january 19th. Cor - PA4

Farhan I know it will increase the price, but how about switching over to the RD16HVF1 which would allow the rig to run from 12V doing away with those wanting more power to increase the voltage to the

Alex when you have your modifications all done can you please post it on here I am interested in doing mine when I get it chris

Bob, Yes, I've seen similar behaviour on my homebrew uBitx. Increasing the drive will overload the PA at 80 meters but will hardly increase the power output at the high bands. I even made a change in

IIRC this is the place where I bought SMD parts some time ago. They still have the day planner hole pattern. I find that very convenient. I put the resistors and caps in one binder and whenever I

Selling my BITX40 to raise sheckles for another rig. The unit operates perfectly, and gets good reports from the Noon-Time Net here in the Pacific Northwest. Equipped with the Baofeng speaker-mic,

Oh my... Pretty much the responses I’ve anticipated...? Nothing should be considered ready for prime time... 1uF caps are big... They exacerbate problems you want (might want) to investigate in

They have, Jack. Well, sort of but you would have to adopt my favourite 0805 size. See eBay item 131871397971 A good assortment and at a good price. So good that any mark up in the price must be

'capacitor kit 1206' -- Though, I must say... pictures are of resistors... which kinda weirds me out. But hey, they're a few bux... What also gives me the jibblies is there's no material spec

You have a lot of experience with NTP servers using GPS. Excellent! I just needed a solution because the USB sound card was too big. So I decided to remove the USB connector from the RPI and insert

Another option would be to make the kits yourself, if you wanted to market them to your club. Use E3 resistor values (explanation

I just ordered two of the "middle" one. I thought I had checked eBay several months ago...must have missed these. Now...off to look for caps! Thanks, Diver!! Jack, W8TEE To: [email protected]

Like this? (Overly spendy if you ask me, but) https://www.digikey.com/product-detail/en/panasonic-electronic-components/CR2A-KIT/CR2A-KIT-ND/251430 If you don't want nice

I wish someone would put together an assortment of, say, 40 common values, quantity 100 of each value and market it for some reasonable markup for resistors and caps. For the club build, I'd prefer

You can increase drive with the preset of the predriver. - f

There is a very strong connection of ham radio and tek. Many of our heros are alumni of tek. They invented many things. I found out they invented the tunnel diode, made their own devices, displays. -

I've found it's never worth it for me to etch my own PCB's. Ferric chloride, and all those other etchants, blech. And, a total lack of vias and soldermask, no
