Re: Pins and colors
Don't cut it! Just label it. Use it power something. It won't work for a lot - the small plug is 'mini' where most 'phones etc. are 'micro' (hard to tell at just a glance) - but it should go in the

Re: Am radio stations
I'm running high side VFO like Allard mentioned and don't have those images anymore. Allard any plans to add BFO to your code? I'm missing out on all the cool features in my hacked up version. 73 Pete

Re: A Good Book
EMRFD sells for $49.95 plus shipping direct from the ARRL. Those high priced volumes are probably remnants from when the book went out of print although it was still highly popular. After many

Re: Schema: [BITX20] Interface
CAT control should be trivial. There are numerous projects out there to emulate Icom or Kenwood rigs. Choose one you like and emulate that one.

Re: A Good Book
Well, I found a copy - brand new softcover with cd-rom - on eBay for $46.11 after shipping. I don't think you're going to beat that - I've crosschecked all my sources. The next best price seems to be

Re: A Good Book
Greetings, One of the most compelling reasons to find a copy of Experimental Methods in RF Design is that there are bibliographical References at the end of each chapter. These References point to

Re: Strange noise
Do you still hear this noise when the antenna is disconnected? Is it in both LSB as well as in USB mode? 73 Allard PE1NWL

Strange noise
Well, I finished installing sketch 1.17.1, added the function switch, and did the PTT sense wire-up. All went well, all new functions work, but now I get a strange noisy loud interference from about

Re: BITX40 Sensitivity
YEP! Had a QSO with a guy in Alabama, he was running 500W, I was running 5W. 20M SSB. Says a lot- my rig probably cost less than his microphone. ($65 for a Bitx20 V3SBL1 and a junked SSB CB for the

Re: BITX40 Sensitivity
The term I heard is "alligators"! Very big mouth and small ears! IMHO high power is useful in controlling a pileup or in bad condition skeds! Raj, vu2zap

Re: si5351bx, a very small set of routines to handle the Si5351
Will come out with a v1 of those si5351bx routines with the following adjustments: ? ? PLLA will have an even integer divide, and integer mode bit set ? ? si5351bx_rdiv will become a 3 element

Re: Interface
I pretty much did everything that Joe VE1BWV suggested for JT65. ? One additional note... one of the purposes of the 600/600 ohm transformers is to isolate the radio ground from the computer ground.

Re: A Good Book
I suggest you download a sample chapter and see if the author's writing style is to your liking. Sometimes the Table of Contents and/or Index of the book is available. ? ?KM4NFQ I agree totally.

Re: A Good Book
Hello Andrew, May I suggest that you go to your local PUBLIC LIBRARY and see if you can obtain any of the suggested titles, to see if any of them are suitable for what you want a GOOD BOOK for? I

Re: BITX40 Sensitivity
I have a much simpler test for sensitivity. I have done careful research and decided that there are a lot more stations that I can hear than stations that can hear me! I wish the folks running the

Re: CW mode delay
Hi Greg, don't worry, I will keep semiQSK included in the firmware. I'm only considering to add an extra user setting so that the operator can optionally choose to use manual T/R switching instead of

Hope the signal generator is not in parallel with antenna. Try with another cable. Many times I have been chasing ghosts when the problem was a frayed connection in the BNC. Same thing happened with
