Re: add yourself to the new BITX operators map
OK, that was a bit off base. ?Looking again, map doesn't show anything more than a pin till highlighted with the mouse.
I don't care if we standardize on just a call or call+name or whatever.

Re: add yourself to the new BITX operators map
Yup, great idea!
Thanks for setting up the map.

Fine with me if you put any info whatsoever in the pop up tag.
A first name would be friendly.
Maybe a URL to a website fully describing all the stuff you have done to your rig.
But I'm not going to update the map every time I try a new antenna or PA supply voltage.
Though might give some indication if I ever get one of these: ?Just so you know, my rig has been modded with a ?custom front panel. ?Back panel too.
If for some obscure reason you need to know my license class, you'll have to check in with fcc.gov
I'd prefer an uncluttered basic map.
Maybe there is something meaningful we could do with the colors,
but I can't think of what that would be.
Color preference, perhaps.
I like blue.?

Re: Making PSK31 Contacts
I agree with Clark. Increase the size of your heat-sink,
especially if you are primarily using digital modes
It is easy to do. Use a computer cpu sink, or go to some place
like Tractor Supply and buy a strip of 3 in x 1/4 in aluminum
and cut your own.
Sometimes you can find them surplus; the best ones I have found
were originally designed for voltage power converters. They have a lot
of dissipation area in a small footprint. Another good place to look is
in linear power supplies, especially the strips used for the amperage
bypass transistors. Sometimes one can also find good ones in old
stereo amplifiers as well (less so in old TV sets).
Always remember to isolate the IRF510 as the tab is "hot".

Re: Other 2 line displays
Phil:
Regarding displays, what you are looking for essentially is a
HD44780 compatible 2x16 lcd display. Usually they are either
back-lit or not. They can have a parallel or serial interface.
You need a parallel interface, 2 lines x16 characters, 5x7 matrix display, with back light.
They come in many colors, mainly green, blue, red, or some variation
of these colors. One of the usual generic part numbers is 1602.
Lots of them now-a-days are pushing serial interface. This may be built-in or add-on.
They will not work with the Raduino, though the serial add-on board is easily removed. The
built-in serial interface is not compatible.
They are available all over e-bay, and cost about $US2.00 each. The only reason one
might want another is to change the color, I guess. Note that something like a 2x20 or 4x20 display
(HD44780 compatible) will also work; they will have more spaces or lines than you need; that's all.

Re: add yourself to the new BITX operators map
Great idea Doug,?
1. need to sign in to Google first to add address.
2. to use as a differentiator of stations¡.some ideas
use the color feature to show something different about your station? Stock BitX40 vs Mods vs 12v or 24v on PA, ?Region, Lic Class (make a difference on contact freq), or anything else that would be nice to know about each other. ?
also, the identifier line could include First Name, or 1 or two other unique ID¡¯s¡.
thinking to make it a pictorial database

Seeing the topics for regional operator lists got me thinking.? If words are good, pictures are better.? I set up a google map that you can add yourself too to help visualize where everyone is located.? I was going to add people that responded to the other topics but out of respect for privacy (and my laziness) this should be entirely opt in only.? The map is only accessible with the link below.? The interface is reasonably intuitive but I will do my best to explain how to add yourself.
go to type your address in the search bar on the top of the map (the box with the magnifying glass to the right)
hit enter or click the magnifying glass
verify the location displayed
click add to map at the bottom of the box that pops up
now click the pencil/edit icon at the bottom right of the box
change the highlighted address to your call sign and click save at the bottom left of the box
you can also add more information to your spot if you choose to

I am making this sound much more complicated than it is.? If anyone can describe the process better please do.

Re: Calling all Midwesterners.
John,
I did just that with mine. ?I added a jack on the back of the rig to plug in a 24-volt supply when I¡¯m operating at home.? The 24 volt connection pulls in a relay that moves the PA power from the 12 volt bus to the 24 volt input.? I¡¯m getting
over 10 watts out on voice peaks, and you are right about the heat dissipation.? I¡¯ll be adding a bigger heat sink to the IRF520 this weekend.
Hoping to connect with more BitX¡¯ers on Sunday night !

Re: Calling all Midwesterners.
For Nick, and Sean. Number one thing I can suggest is push 24 Volts in to the final. It's very easy to add in another supply jack for powering the final separately.? Double power in = triple power out, greatly improves your QRP signal strength. And you don't have to do the alignment process again. It's not going to change that much. Be sure you have enough heat dissipation. Combine this with a high antenna and you could topple W1LY as QRP king of the mountain.
My problem is they hear me, but I can't hear them. I wish all BITX'ers would include 24 Volts as a switch in option for when it's needed. I used the extra hook up wires with one set on each DC Jack, and just open the box and swap connectors on the board. You'll need a higher voltage supply and a buck converter to step it down to 24V.?
Sean, I think you are one of the closest stations to me and we should be able to hear each other even with 12 Volts barefoot.

Must be 2 line as the menu, comes up on the lower line, and would rather just a plug in replacement.
On the search for hardware, seems to be a bit of a short supply, mainly knobs. Need a decent sized knob for the tuning control.
Just trying to work out the front panel layout, and either front or back may have a USB socket for updating the Raduino.

Haven't been able to make any contacts yet. Tried with a home brew end fed wire with home brew L-match. Also tried with a home brew magnetic loop. No one ever comes back. Seems like everyone I try to call is running something like 800 watts and may have attenuators on. :( Same thing with calling CQ.
Meter shows power and no reflected when tuned. I may try a dipole next but I do not have the space for it.
