Sorry. I got lazy. http://kd5ssj.com/solderpaste/smt-tools-and-process Very informative. I haven't tried the beverage warmer he talks about to preheat the board. Good idea, though. I usually just

Hi, Gary (Shriver)!? You were curious about DHL shipping.? I just got my ubitx this afternoon.? I ordered it 12/23 and it shipped day before yesterday.? Here's the path it took (from bottom to

I rarely do. Sometimes I'll tape a hunk of fish paper over a thru-hole I think might not like the heat. Or I might cover a previous SMT part that might come unsoldered and get misaligned or blown

one or the other. the object is to noy let the base of the transistor float. tayda make before break 3/4 position .089 $ each. no 10k needed.

now operational, see here ( https://youtu.be/Du3TIS5UPJc )

is there a simple way , like a/d converter, to take an analog voltage and offer it to a device using the PE3402 ? The A/d converter would need 4 bit output. ijnfan-HamRadio@...>

I just posted these, and more, on www.ND6T.com ( http://www.ND6T.com ) More to come. Have fun! -Don, ND6T

It's a heat resistant tape that's flame resistant and good to 600F (intermittantly). I know it's also used with heating elements and is used by some on their 3D printers. I bought it 'cuze I have

Also I cannot read the values of the Caps due to pixelation.? Could you provided those values.

Could you provide the number of the transistor?? Yes, I am that needed.? LOL Thanks

Mine shipped same date, picked up Hyderabad 16:38 their time on the 19th - took 24 hours to get to Bangalore (got there 1646 on the 20th) and got hung up in Bangalore for some reason. Finally left

Eric, Couldn’t find your earlier link to “Cash’s video”. Could you re-post. Thanks Mike K5ESS Sent: Wednesday, February 21, 2018 12:07 PM To: [email protected] Subject: Re: [BITX20]

So do I need both the 10k ohm resistor from c1 to ground and the make before break rotary or just one or the other?

Paul: I ordered the connector shells/hoods from Tayda. "Housing Connector 2.54mm" Pins 2, 3, 4, 5, 8, 12 Part # A-826, A-827, A-828, A-829, A-832, A-835 Ordered a mix of sizes (+/- 300 total).

uBITX ordered on 12-23-2017. Received shipping email on Mon, Feb 19, 2018 5:29 am with DHL tracking number. It was delivered to me on Wed Feb 21, 2018 11:55am. That was definitely worth the

2 more things, a 10k from + of c1 to ground will stop voltage screaming to the rail while changing it with power on. if you go to a rotary make sure it is make before break and the spike wont happen.i

THE ZENERS SET THE PASS VOLTAGE OF THE 100 VOLT 10 AMP DARLINGTON. sorry caps lock. they are 1 amp devices but the transistor slaves them to 10 amp handling. i have used this ciruit fo over 40 years.
