Encontré toda la información para este proyecto en este sitio. www.sillanumsoft.org/Italiano/zrlc.htm Espero que te sean útiles

You can find all infos at this link: www.desertcoins.altervista.org/files/Coils-Details.pdf and the manual at: www.desertcoins.altervista.org/files/Grid-Dip-Meter-UK402-Manuale.pdf

thank you very much

unfortunately not, they were discarded parts for the Fiat-Allis tractor set-up where I worked.

you can download the pdf in the description link, then you will have to adapt the measurements with a graphics program, at the time of construction I drew everything by hand

What exactly do you want to know

puoi trovarlo sul mio sito: www.desertcoins.altervista.org/files/Amtron-uk-406-diagram.jpg

here is the original magazine where I got the project, www.rsp-italy.it/Electronics/Magazines/Nuova%20Elettronica/_contents/Nuova%20Elettronica%20212.pdf

It is a system of connectors made with 3D printers designed by me

vero e non ha mai bisogno di spray sui contatti ;-)

Assolutamente vero, infatti io ero squattrinato e fare la scala faceva parte del passatempo.

@@fabriziomarzi-cm6to beato te che lo "eri" soltanto :( io continuo ad esserlo, ho fatto un elenco dei componenti, devo vedere solo se ho un cond. variabile da tipo 90+90pF, il resto ho tutto, sono alla ricerca di progetti decentemente interessanti da fare... vediamo che mi invento per la scala, come stampante ho solo una di quelle che stampa le etichette su carta termica LOL come larghezza però dovrebbe bastare

@@fabriziomarzi-cm6to comunque ho dato un'occhiata più a fondo con i GDM e ce ne sono diversi di cui si trova lo schema, mi sono convinto a fare quello che si trova googlando "GRID DIP OSCILLATOR by SM0VPO" ha diversi vantaggi rispetto a quello che hai fatto tu (sembrerebbe), molti di questi "hack" si possono applicare anche al UK402 ma tanto vale che faccio l'altro, di condensatori variabili ne ho trovati di adatti, ma a me servono anche frequenze molto basse ed il UK402 non è garantito che funzioni sotto qualche MHz

Thanks you

For the look I was inspired by the Heathkit HD-1250, obviously mine is very handcrafted

it is homemade with little expense and recycled material, you cannot expect absolute precision but for me it is more than sufficient

It's not intended for exact measurements

sorry, my English is terrible, and google translate doesn't work miracles

today everything works with microprocessors but these devices still have their own charm

In the seventies somewhere I made one with an ECC85 tube in a very compact box. Unfortunately i dismantled it, I needed the double varco with ball-drive reduction for another project. Later I bought the famous Tridiper from Hanssen witch I still own. In that days I used it a lot for my homemade projects such as (hamradio-) receivers and transmitters

I often regretted having dismantled old instruments to recover components but I was a young man with little money, however many of my friends in the 70s used grid-dip to calibrate antennas.

muchas gracias, cuando un proyecto funciona me gusta cuidar la estética.

On the signal generator, sine generator and signal tracer I printed a panel on plastic adhesive sheet, in other instruments i used trasferible letters

@@fabriziomarzi-cm6to well done, very good result!

2 volt for mH and 200mv for uH

thank you

Thank you

Grazie

Thanks for appreciating again

In realtà era il vecchio Alesis Midiverb II che rimane ancora uno dei miei preferiti.

sempre una gran macchina!!! ;)
