Hi Jeff,
Thanks for the information IT Works - I am sure others will be helped by your suggestion also.
Not being attuned to unix commands you were a great help

Thanks Again

Re: First Contact using BItX40 - Lithuania! #bitx40 (Tried 7.277, too much BCI here!) #bitx40

In the EU as you know we are limited up 7200. Maybe it would be just convenient to use standard qrp frequencies (CW/SSB) to meet other qrpers.

(Laugh!)  First contact with the BitX40 - 5126 miles!  (Shows the importance of good band conditions!)

Congrats Bob!
It's still amazing what results can be achieved with this little gem!

If I understand what you are trying to do, you must put yourself in the group which is authorized to use that port to get out (dial out) to devices.

Re: RX BCI filters

 

If anyone has been trying to order a kit and could not get the order through it was a slight mistake on my part please refresh and try it again now with the kit option!

sorry for the mix up and thank you Steve AA7U for bringing it to my attention.

Re: Ubitx v5, nextion 3.5 display, AGC, and 3d printed case for sale

Brent D
 

Can you link me to that case? I printed this one (link) but I'm getting electrical interference from the cable (I think). I couldn't find any other case that supports a 3.5 screen... most seem to be 3.2

Everything else I printed looks very similar apart from the face, so hopefully I'll only have to print the face and not the whole case.


Thanks much!!

Re: RX BCI filters

 

Filters have been release!

I will have plots and data up soon, working on getting better screen shots.

Looking for 180 shipped and will include any unused parts.

Ubitx v5, nextion 3.5 display, AGC, and 3d printed case for sale

jasonnp@...
 

Selling my Ubitx V5

Just not using it, so figured it could go to a better home.

Has the Kit projects AGC installed (it is hard wired for the slow setting)

Has a custom interface on the display that I laid out myself (Looks like most others just updated graphics)

Case is 3d printed but isn't 100% perfect, but still very nice.  

None of the wires have been shortened so if you want to change the case there is plenty of leads on all the connectors.

It's a project so it's not perfect and it's never done but I figure you understand that!

Thanks!

Re: 7.277mHz Sunday Afternoon

Bob Fischer, Fischer Technical Services
 


Thanks for the info, Skip.
I am aware of the MMSN.  They run noon until around 10 PM ET.  I check in with some regularity. 
14.300 is also home of INTERCON (the old Intercontinental Traffic Net).  They run 8 AM - noon ET.  I check into that one too.
BTW:  I checked into INTERCON yesterday morning with my uBITX.  Operating "remote" from a hunting camp in the middle of a wilderness area. (West Virginia Wildlife Management Area).  Operating battery-solar into an 84 foot longwire.  Net OP was W5WAZ near Houston, TX.  Also worked the Battleship New Jersey with the uBITX & same setup yesterday morning.
Amazing little radios.
I will be listening on 7.277 - just can't do it today.

Just to let you know 14.300 is the Maritime Mobile net frequency for both coasts. They are in operation most of the day with net controllers throughout the country. It’s not the best choice for operation and meeting place for uBITX users but could be used to possibly get a signal report.

I have listened a few times but never heard another uBITX on 7.277.  The posted net time is a little inconvenient for me.  I have another proposal:  How about uBITX addicts just "parking" our rigs on 2.277 MHz and listening.  I usually have mine on, with volume down very low.  I have been leaving it on 14.300 but 20M propagation has not been good lately.  I will start listening on 7.277 for a while.  I encourage others to do likewise.  Make your first CQs there when you sit down to operate.

Hi Mark,

Thanks for digging into that minimal detectable increase question. 

And yes on the frequency response of the ear, I may have sacrificed a few octaves to 60s music.

And for me, a 1dB difference was reliably detectable, so I would go by the 1dB figure if their recordings were correct (dB and not dBV or dBA).  Anyway, mainly I meant that one can hear power levels at the speaker a lot less than 125mW.  Of course it all depends too on background noise in the room environment, the speaker, etc. as  125mW in a  car going down the road won't get you far!

And if you want to get depressed (or impressed) by how much hearing loss you have or don't have:

Recall though that we need a doubling or halving of power to notice a  difference in volume, so you could actually be seeing voltages much less than this.

Mark, I don't think that is correct. I believe 1 dB is discernible to most listeners.
