I enjoy the QSO night very much, it has exactly what I like in ham radio.? I enjoy listening in and hearing different conversations around the country.? I like the CQ format instead of a directed

I listen most Sunday nights and will jump in when I get my disemboweled BITX40 back together. Last night conditions were horrible here, but I heard a number of CQ-BITX's, including Willy. My question

This thread is your opportunity to comment on the format and operation of the BITX40 QSO Night, which is our "net". Any comments or suggestions are welcome.? Some ideas for discussion: Is the day

BITX QSO Night, Sunday, September 3, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere Join us as we make contacts from BITX40 to BITX40 on 7.277 MHz in 40 meters! To participate, call

I'm also interested in a BITX-6 for portable operation. ?Allison KB1GMX built one 10 years ago, she reported the need for an additional RF amp stage, a better BPF, replacement of the first 2N3904

Very nice. ?Good complete explanation. Thanks! I've never quite figured out the difference between PIN and regular diodes. Apparently a PIN goes into some sort of free-wheeling mode where it

??? How would one educate an antenna? The word would be "taut" - ain't English wonderful? Particularly Brit-glish. Take the King James Bible's "strait the path". No, it's not a misprint or typo - a

Hi Jerry, The diodes are BA479G and are available from Mouser. ?They are PIN diodes, designed for RF attenuation. ?The voltage controlled RF attenuator in the diagram is variable, attenuating

I doubt you need any special PIN diodes, as the RF signal voltages never exceed the bias voltages. So all diodes could be 1n4148 or 1n914. ?If I am right.

Scratch that, the chokes are there only to block the incoming RF signal.

That looks pretty good to me, may try it. The Bitx40 probably has more RF gain than is required (if you have a decent antenna hooked up to it). So a simple attenuator like this is a good choice,

I set up portable outside the house for about three hours starting at 19:00 Pacific time. I heard a few murmurs on 7277 KHz, but nothing that I could copy. I put out lots of CQs, but eventually

Called CG BitX for 45 minutes on 7277 from my southern Oregon location beginning at 7pm Pacific time. No stations heard. Thomas W Noel KF7RSF

Hi Jim I was looking for such AGC: Thanks for sharing.- 73 – LU5DNM De: [email protected] [mailto:[email protected]] En nombre de jpkellyburbank@... Enviado el: domingo, 27 de agosto

If you want to try a nice alternative to traditional heat shrink, check out the "Liquid Tape" sold by Lowes, Home Depot, amazon.com and others. A four ounce bottle with brush applicator is only a few

I made a few contacts at 7 EST. Then I switched to the 3905 CCN 40 meter net. At net start, quite a few stations could hear me and work me. However, by the time my turn came around, at 9 PM local,

Yes, these look right. Thanks Kevin.

It should be 82. Jack, W8TEE To: [email protected] Sent: Monday, August 28, 2017 5:58 AM Subject: Re: [BITX20] U3 on W8TEE Schemtic In?B40AssemblyManual03.doc R1 is listed as 10 ohm not 82,

You're usually better off buying from their website rather than their ebay store. www.taydaelectronics.com Vince. -- Michigan VHF Corp. http://www.nobucks.net/ http://www.CDupe.com/

Yes Tom, I am using a velocity factor of .8 for the foam core RG6. The stub is around 7.9 meters. The antenna is coated wire. Listened late with nothing heard, but did roam up and down the band a
