Re: Usb sound card.
If you're using FLDIGI take a look at??
The PTT tone on the right channel eliminates the need for a USB serial adapter and relay circuit; you only need the mic and speaker wires between the sound card and BITX40. In my setup there is no difference in performance with or without the transformers but they're only $1 on Amazon so why not. |

Re: CW Offset does NOT work on Raduino_v1.14.1 for BITX40
TKS Allar,
OK but it is not a display issue. 800Hz frequency shift does not occur so I can not QSO with hi.. When I attach the voltmeter between "A0" and "GND" the problem is solved sometimes but not stable. hi... Maybe the "A0" PTT-SENSE signal line should be pull-up or pull-down? ja9mat hidehiko. |

Hidehiko-san,

The frequency as shown on the display is always the TX carrier frequency. In CW mode, the RX frequency is shifted by 800 Hz, not the TX frequency. 73, Allard PE1NWL On Wed, June 14, 2017 11:58, qrper72@... wrote:

Re: BITX QSO Night, Sunday, June 18, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
I have been listening to 7.277 a bit while sweating in the shack. So an anytime BITX40 calling frequency must be a good idea. Now, does anyone have a youtube for dummies video they especially like about qrp spots, and dx summit? I haven't focused my energy that way yet. I guess nows the time.
I heard Mexican activity last night on 7.210. It would have been no problem to work with it I had a regular radio. to be rude and talk over them with. Do the extras want to have a frequency just for them? it's okay if thay do. |

How about using QRPspots? ? to advertise frequencies in use by BITXers? This is also a good idea but it does not need to be limited to Sunday night at 7pm.? Anytime that band conditions seem good would be a good time to post at and . Post in this messageboard as well to see if anyone else is interested.? |

QSO night next 7178 & 7277
I agree that Spanish speaking stations operating on 7175 would suggest that we go up a bit.
7178 is better, going higher gets interference from group operating on 7181. A couple of weeks ago, I had a high power station tuning up on top of us. I cranked up the power a little and cleared the frequency alerting other stations that QRP is being used on frequency. Willy heard me and I guess the guy tuning up did too. I know that a lot of us don't have the power to fight back the QRM. I can go from 5 to 1000 watts. If we need to clear the frequency we will. I'm in Iowa maybe an East Coast station could do the same. Ed |

Re: Standoffs for mounting the board
I recommend you to assemble the standoffs with loctite 242. I think the best option is to use the bolts instead of tapping the ?enclosure? 72!! El 13 jun. 2017 3:55 PM, <davidzdeb@...> escribi¨®: Excellent! They have a M3 0.5 tap! |

Re: W8TEE VFO Board
Jack Purdum
Hi Ken: Yes, it would be under the OS License Agreements. As I said before, my goal is to get as many of you messing around with microcontrollers and the associated code as I can, and this board brings out a bunch of I/O pins that you can easily play with. With 54 I/O pins and 256K of memory, some of you are going to come up with some really neat stuff that we hope you'll share with us.

Release it under an Open Source license. A license gives you and others specific rights. It is very difficult for me to read. I had to copy paste the content of the wed page into a text editor to read it.The worst-case scenario is that the Chinese will produce the board for less than what you are asking for it, and offer free shipping to boot.

Re: WANTED VK3YE LED LDR AGC diagram

Try this, may help. tracks run left to right, breaks are where the blue dashed lines are. Did try photographing the tracks, but it does not help. Pot for S meter, depends on the meter. Phil - G7BZD On Tue, Jun 13, 2017 at 8:22 PM, philip yates <phil@...> wrote:
