For Sale / Wanted / Barter / Swaps only - Crystals
« on: January 24, 2021, 1714 UTC »
I have the following crystals I would like to swap if anyone interested.

(Marked) 5836KHz - Tested in TX 5836.85KHz Believe this is a HC6
(Marked) 6205.208Khz - Tested in TX 6206KHz  Believe this is a HC49
(Marked) 6245.83KHz - Tested in TX 6246.60KHz Believe this is a HC49

Would like to do a one for one swap for the above for other parts of 6.2MHz - 6.4MHz (but not 6.4MHz!)

Please note not looking sell only swap or if you have some for sale please let me know

Thanks

It's under 10Watts and antenna is a Inverted-L, so not ideal for this band

The RF Workbench / Re: Someone had Corsair II AM TX experience?
« on: January 17, 2021, 2024 UTC »
Sorry to resurrect a old thread!

A few years ago I had a Dave Martin built Corsair that I purchased off someone from Facebook and remember it having poor audio, I don't know if the guy I bought it from had played around with the insides but it sounded distorted on air so I sold it on!

Recently I came across some pictures I took of the insides of the one a sold and seeing a post on another forum of someone who recently built one I decided to order the bits and reproduce my own.

I built the experimental gate modulated version to roughly the same size and layout as Dave's versions with images I had and found on the other forum. This did have the same issue with distorted audio and they only way I could improve it slighty was putting a 10nf capacitor across the 1uf capacitor but wasn't great.

Today I finished a 2nd version of the experimental gate modulated version but the layout is completely different and I can say it noticeably better with no distortion to the ear that I hear.

So can confirm the experimental version works ok  :)
