Bandspread

[LA1HU]

Hello all paraset friends

After practicing the paraset on reception, and thinking about how difficult the RX is to tune, I think I will choose to only prioritize the 80m band. Preferably get a band spread that covers the cw portion of the band from 3.5 Mhz to 3.6 Mhz, but preferably a little over but not too much.

Does anyonehave experienced in this to share ? schematic, etc. i would be glad to hear from you.
Thank you for your feedback

I found this - maybe this will turn out ok for me.
(Will send you a email Henk in case you have the RX coil parts and caps. for me?)

Btw. it does not look like paraset.co.uk is active anymore. Tried to send them an email but could not be delivered.

I put a series 40pf mica cap with the tuning capacitor. Added a 70pf trimmer capacitor i parallell with the series caps, and adjusted that to reach 3500khz on receive.
A better approach would have been a 10pf tuning caps, to better coincide with the 0-100 marks.
