Wonderful... scouts and spies... all kids must learn Morse Code at certain point of their progression. They play with it using flashlights, why not use the real thing, introduce them to CW.

Hi, a friend wants to replace his 30+Y old stuff. I said experienced hams use Rigol stuff, which good models would you suggest that do not cost a leg to be used with modern and vintage PA/rigs?

This sounds like a ton of fun! How about a ham radio escape room? Make up a fictional scenario whereby the kids must assemble a radio station to call in a rescue or pass on secret spy intelligence,

Mine is like yours, injecting a signal of around S3 was clearly audible anyway, that swap does not jeopardise anything.

AndyH, Yes rebias. Allison

Sascha, Have you checked the wiki and http://ubitx.net/ ? Info in both places. The bias at Q20 should not be about 6V. It should be more like 9V. Reason for this is the ideal bias is about 10mA and

Hi people, With respect to measuring uBITX harmonics and spurs, has anyone had experience of the OWON XSA1015-TG Spectrum Analyzer? Any comments? Thanks in advance and 73. Kevin VK3DAP / ZL2DAP.

If you are looking for a hands-on project I suggest the Clothespin Key- https://docs.google.com/document/d/1wGiIayfZiR6aSwtswXzSAYevBNEw-cT3si7MRxMvjeE/edit I would also suggest sending them home with

This is how I got started in ham radio in 1954. We did a field trip to W8FTQ's QTH in Medina, OH, to hear his weekly schedule with his son...in SOUTH AFRICA!! The hook was set and I've been licensed

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 :) Joe

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

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.

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

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

The Bands are far from dead .... People with damp shoelaces for antennas say they are ... Gw0wvl
