Another way to check for linearity is to use pink noise as an input: all frequencies in the pass band simultaneously. A perfectly linear system would reproduce exactly the input spectrum as the

Be careful when conducting 2 x tone tests.? You can easily manipulate / skew? the results by? manipulating the tone spacing.? ?Manufacturer's would do just that, years ago, to minimize IMD3 and

Dimanche, 19 Janvier, 2025; 1148 EST Dear Francois, XCVR = Transceiver, a Transmitter and Receiver in the same box. Often referred to as "Tx or TX," and " Rx or RX" thus:

Francois, I've been experimenting with a RFZero board. RFZero is an Arduino based signal generator with many, many different applications. The RFZero team has written Arduino scripts available for

I would like to understand your participation but I am already very constrained by the use of abbreviations and certain words that Google does not translate for me. · xcvr xcvr's ·

U can test a xcvr? with a 2 tone....? but not a linear amplifier (the exception being if using a xcvr with Class A, like the yaesu, and even that won't work in my case, since the MK-V only puts out

Francois, There are a number of 2-tone software apps that could drive a computer sound card with very high quality output.? If you have a computer (or laptop) near the workbench or shack, maybe

Yes. No problem. vk6apk@... 73, Alek VK6APK.

Alek, Can I send you an email on this? I possibly would be interested in it, just need to talk to someone and see if we still need it or not. Thanks

Bonjour Francois, The last two-tone generator I purchased was a kit from Elecraft. Hal Mandel W4HBM

Hello Do you have any recent experience of buying a generator of this type. Please send me references of such a product. Thank you -- F1AMM Fran?ois

The relay control on the GM3SEK board became messy when using tetrodes or triodes with handles. There was also external parts that there were not documented? that had to be added externally for

Yes. I bought the complete WD7S kit years ago and then decided that it was much simpler to include the features that I wanted in my amp constructions without the board. I still have it here, as I

For simple GG triodes,? do u really require a triode control board ?? ?The step started HV supply, and step started? fil supply can be done? without the triode control board.? ?Ditto with grid

Mine are? the model..... ODC-15A? ( 15 vdc input side, and a huge plus / minus range)? ?and are rated for 250 vdc @ 1 amp on the output side. The other version is called a ODC-15, and output side

Alan, Jim, I sure like that. I downloaded the datasheet. I'll look more into these. Thanks! Bob W4JFA [email protected]> wrote:
