"Spy" transceiver with two tubes. NEW DESIGN!!! 

Extremely interesting two tubes 80M band transceiver in a handy box. I always enjoy what you have created. I hope to make a CW QSO with you using my classic transceiver when the propagation is right. Thanks for sharing with the world on your excellent achievement....VA7VB

Wonderful creation! I used to sit and observe my HAM neighbour as a young boy . He was kind enough to allow me to listen and observe . He was a U.S. Army Retired Colonel who was General MacArthur's Communication Officer. He was teaching me Morse Code when he died in 1966. Your videos have awakened an interest in radio and HAM devices that I've not had for almost 60 years. Thank you!

Ok, this is awesome! I thought your separate tx and rx videos were good, but this is another level. Thanks so much for sharing 👍

Very interesting concept! Your videos are always excellent. Please continue to share your work with vintage German equipment!

Only two tubes, and full break-in operation! Plus 600-Hz offset and side-tone -absolutely fantastic! I must now build one for 40-Meters :-) Thank you Helge ! -KK7JD-

Helge.. every time I come back to your channel, you did something new amazing. this is a so elegant solution .. I am really impressed

simply amazing, I would love to build on...I only lack in the electronic component experience...fantastic!

Simply brilliant, I loved the way to generate the beat signal on RX using the same crystal as to generate the carrier on TX. And all in a tiny box. a fascinating experiment 73 of EA1FLL 👍

keep it up! These miniature tube projects are really fun!

Congratulations! I am very happy to watch this homebrew two tubes transceiver making the first successful QSO and the extremely satisfaction smiles that you exhibit after the QSO. I assume that you are extremely happy and satisfied. Great job...James VA7VB

Nice little rig! I want to make one too😀

This vacuum tube technology could survive from being obsolete in the 21st century. Especially from a tin lozenge box.

Very nice little transceiver, amazing. Kind of a tube version of a Pixie 😊. How high is the supply voltage, I can’t find that info in the video or on your website.

Excellent job Helge....hpe to see you on the air for QSO 73

Great project. Super, You are big men.

Hello dear OM the Reception part works very well now please give me the diameter of the RF coil for the Transmission part and the number of turns Thank you again 73 jean-jacques F6ggz

Excellent Job.... 💯👌

Thx u

Nice work.

Så morsomt og vellykket prosjekt - artig. Gratulerer med et så bra resultat i et så liten boks :-) Hvor har du kjøpt disse boksene ? 73 de LA1HU

perfect..

Thanks

Beautiful. W5NU

Thank you dear OM for your answer one last question please for the coil of the EL90 if possible the number of turns and diameter of the coil many thanks 73 qro jean-jacques F6ggz

This is cool would be fun to play with on the air. I wander if it can operate at higher frequencies like 17m

Fin video Helge -og et interessant prosjekt. Når jeg ser på skjemaet så er det en ting som kan forbedres: du legger inn en kondensator mellom volumkontroll og gitter på første rør, og en fast motstand mellom gitter og jord. På den måten vil arbeidsbetingelsene for røret være uavhengig av volumkontroll. 73 de Asbjørn, 5MT.

Hi, something more about output audio transformer? Size/source

hello dear om i am interested in the assembly of your 2 tubes transceiver can you give me the number of turns for the coil of the ek90 tube and the 6aq5 a big thank you 73 qro jean-jacques f6ggz
