Ahh the good DP0GVN station in the Antarctica. Looks like we reach the same stations abroad.?

The bands are not dead they¡¯re ?just not doing SSB :)

Boy Scout activity event

 

I am looking for some ideas that can be used in a 30 minute window, or less, to introduce ham radio to a dozen scouts. My idea is to employ a few HTs in simplex mode, divide the the groups into 2 or 3 per team. Have each team search for something ( not defined) using the HTs and clues to where the something is located. Each team will have a licensed operator with them during the activity. Also this will be an evening event in a church activity building. Any ideas welcome. This is an opportunity to spark interest and get involved for the scouts.

Great news from HF Signals!!
I asked: If I order a BITX40 now when will it ship?
They replied: It will ship immediately

Order submitted. Thanks for all the replies. I will update here when it ships.
Re: ?BITX: CAT connection

 

I have set mine up through the USB to work with N1MM logger Plus and it works just fine. As said before set it up as if it is an FT817 and it will do everything even the CW keying.
My uBitx is set up as radio number 2.

Presently I Am using Memory manager the new version 1.1 (I think) to set up, the WSPR beacon but cannot get the uBitx to load the settings I Have uploaded with the Manager.

Does anyone know how to do this?

Re: weak signal fun #ubitx

 

People love to cry that the bands are dead, but do very little to make activity. Combine that with poorly built stations and folks who don't like to work for contacts or use digi modes, and thats what you get...

The bands aren't dead, things like WSPR and FT8 very much prove that. Just different conditions that require different tools.

OOPS???? I went and looked,?? I thought mine cost $135 but that was with a case and faceplate.

So, I would sell it for $90 plus freight,? no case (has my call sign on it).

I do not know if mine is a 40 or what but I bought it about three months ago. I am not going to build it I am going to sell it. ?

Hi folks. Was getting ready to order another Bitx40 and noticed that my order wouldn't ship until after December 25th. I guess I'm wondering if that is correct lol... thinking (hoping) that's a misprint.

Re: HF Signals still back ordering? #bitx40 #ubitx

 

Timothy (and TR),

My board has etched in copper "Bitx40v3 (C) HFSIGS.COM, 2016"
I doubt that PC board has been updated since then, if so it wasn't mentioned in the forum.
D15,D16 have a little diode symbol in the silk directly under the component.
That might be what you see in the photo and figured was a component marking.

If he's a hired gun, he probably gets all the dog boards that other folks give up on.
Not surprising he would run into the occasional head scratcher.

On my Bitx40, there was some sort of short under C107.
Must admit, that took me awhile to figure it out.
Removed the cap, it ohm'ed out fine, didn't see anything?wrong with the board.
Cleaned everything with alcohol, put it back, and all was well.
Perhaps a solder whisker shifted over a few microns in position during shipment,
or some solder flux picked up moisture?
But these do get checked out at HFSigs before shipping.

Would be interesting to take good random poll of forum members, see how many?
had trouble with the boards as received.
We hear tens of people with trouble in the forum, but there are thousands of boards out there.

> I get the feeling though that I was the only one who gave half sensible answers to is queries a while back.? (many by PM).

I vaguely remember somebody talking about stuff not being right and buying all new crystals.
And I may have posted my best shot at an intelligent response,
though I've been pretty busy these last few months.
Seemed the wrong approach, but wasn't going to argue.
Lots of people think I take the wrong approach too.

Jerry, KE7ER

Re: Apparent component swap in design and assembly of pc board v3 #ubitx-help

 

¿ªÔÆÌåÓý

Really? R37 and C32 are in series, so the order makes no difference, although the schematic is drawn incorrectly. Fix your schematic.

According to the schematic v3, capacitor C32 should be connected on one side to pin 2 (emitter) of Q32 and resistor R36 and the other side to R37.?

Correction can be made unsoldering both components and swapping them again.? Just the wrong silk screened references will remain.? Any advice will be appreciated.? Thank you!


Re: Apparent component swap in design and assembly of pc board v3 #ubitx-help

 

My V3 board was from the 2nd batch late last December and is exactly like yours.

The boards are updated continuously - the schematics, not so much.

Advice?? Wire is up and run - mine works beautifully!

Jerry;? ? at the D16 posn I appear to be looking at the SMask on the PCB - best photo that I have. at D15 there appears to be shiny solder but there could be no component placed.
