Re: gluing toroids to board
¿ªÔÆÌåÓýWe can use silicon RTV neutral grade for long life & flexibility . I am using it in my HF amplifiers with stands transportation jerks of the finished products even with larger toriods. Krish, vu3nkk ? From: [email protected] [mailto:[email protected]] On Behalf Of Ashhar Farhan ? we use a quick-setting glue akin to superglue. - f ?

¿ªÔÆÌåÓýYes! Just a Dab of Hot Glue works Perfect! I mean like an 1/8" dab. On 6/18/2017 6:56 PM, Sasi Nayar wrote:
Realising how delicate these toroids were, I hot glued them when I first got the board. They work fine and is sits there snug tight |

Re: BITX QSO Night, Sunday, June 18, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
I waited a while to make that suggestion about 7.210, it still didn't work out anyway.

I got another late start, and this time I plan to listen for Bitx'ers loud enough to understand, instead of me calling CQ.

You can also use the built-in function of the IDE to update the library to the latest version 2.05 73 Allard PE1NWL On Mon, June 19, 2017 02:09, Fede wrote:

Hi Bill,
Very happy to have my first QSO Bitx to Bitx. I know my report was 33. Your signal was better, at about 36. Anyway my callsign is VA3NOI. My fellow Canadian VA3NFI does not own a Bitx40. Thank you for the contact and 73, -- Ion VA3NOI |

Re: BITX QSO Night, Sunday, June 18, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
I was on from 7 pm to 7:30 pm EDT.? Very happy to work KC8WBK, N9ARZ, VA3NFI, KF4WBJ, and WI1B.? WI1B was not on a BITX, but he has?one in the shack and?will put it on the air soon. I was running my BITX DIGI-TIA (Digital VFO/BFO and?Termination Insensitive Amplifiers) to a CCI EB63A amplifier at about 100 watts.? Antenna is a dipole. I think we did?pretty well, considering?the band conditions.?? 73? Bill N2CQR?

To participate, call CQ BITX at 7pm sharp, your local time, on Sunday. Call off and on for about 15 minutes. It is helpful if you call CQ BITX with your name and location.? Repeat your call a number of times if conditions are weak. This is a worldwide event at 7pm in each time zone.? You may participate in any time zone, regardless of your location, so you may wish to call in at 6pm, 7pm and 8pm, your local time, to contact hams in adjacent time zones. Report your QSO's, discuss propagation, noise, signal reports, audio reports, antenna type, etc. in this thread. This is an undirected, scheduled event.? The BITX QSO Night relies on you to call CQ BITX to initiate contacts with other stations, so warm up that final and transmit a few calls at 7pm on Sunday.? Talk to you then! |

Jack,? After changing: ?text size in line 302,340,376 ?the sw1, sw2, sw3 ?now look good - right place right size. text size in line 850 was a 4 now a 3 - frequency correct size and fits perfect.

new SI5351 library tested OK on Raduino
Yesterday Jason NT7S released a new SI5351 library version 2.05 on github.
In the past it had been noticed that previous versions (2.02, 2.03, 2.04) produced strong clicks/pops during tuning. These clicks were caused by the PLL being unneccessarily reset each time the frequency was updated. For this reason it had been advised to use v2.01 until this problem is resolved. The PLL reset issue is now resolved in the latest library version 2.05. I have installed the latest library and found that it indeed works OK with the raduino code. So we can now safely use the latest SI5351 library version. Thanks Jason! 73 Allard PE1NWL |

Re: BITX40 package size
Where was the bit of track? ?Where was the spark?

Might yet be brought to life. But at $59, a reasonably cheap lesson in what not to do. On Sun, Jun 18, 2017 at 02:57 pm, <mattcarus@...> wrote: small spark then nothing (raduino dead too ?) - clearly that bit of track was acting as a fuse.? |

Re: BITX40 package size
Right, got some time in front of the BITX again - here's an update...
Incorrect polarity was the original problem so fixed that. Powered up and everything looked OK - raduino lit up, no smoking parts, however no audio out either. Checked audio jack wiring and it looks ok, also no leads shorting out or anything like that, hmm ok, it's getting late so I'll try another day. Putting it all away I noticed a burnt out track on the bottom of the board. I'm getting a bit impatient and instead of checking what the track is, I just replaced it with some jumper wire and try power again... That was a mistake, small spark then nothing (raduino dead too ?) - clearly that bit of track was acting as a fuse. Packed it away again, slightly more annoyed than I was before (annoyed at myself, that it). I'm rapidly coming to the conclusion that I've probably damaged it so much that simply replacing it would be the least painful option. Matt 2E1HNK |

Re: Shielding plastic cases
Master Ice
?
Why not try the RS components spray on
screening, stock 247-4251.
It
gives a?silver plated copper shielding coating designed to give low
resistance even in thin layers on plastic electronic
housing.
I
used to use an earlier version professionally on cryptography equipment to help
limit compromising emissions.
It
worked very well and is intended for plastic.
It's
not cheap though.

Re: Shielding plastic cases
I cant understand why some go to the trouble of buying a plastic case and then have problems about screening and not get an aluminium of steel box in the first place. Obviously aluminium is easier to work with. A bit of exercise with drills and files to drill and file holes as required will do good to everyone. Just take it easy and remember to measure twice and cut once. Regards Lawrence On Sun, Jun 18, 2017 at 7:51 PM, Kevin Gilot <kevinemtid@...> wrote: Thanks for the photo. When I thought Tape I was thinking strips of 1/2 inch or so across the case. Not fully covering the inside of it.? More of a Cage rather than a Box. Okay, makes sense to keep of the stray RF and such.? |
