Ceramic Resonator Regenerative Transmitter - Receiver for 7 MHz CW

Building on the ceramic resonator regenerative receiver recently described this transmitter-receiver uses a 7.160 MHz ceramic resonator in a companion QRP CW transmitter. Housed in the same box as the receiver it allows operation in the bottom 60 kHz of the 7 MHz CW segment.
Note: At 2:26 there is some text in the diagram which may be unclear around the choke in the collector of the BD139. The text reads ‘3 turns choke FB’. It’s 3 turns on a 6 hole ferrite bead.

Nice little rig! I know because I recently build it. The audio was to low for me, so I build in a small 386-amp. Missing a sidetone when keying, so a simple one-tr osc is inside. The RX is easely overloaded at evenings, so I put in a switch with an 18 ohm Attenuator, when needed. I was getting over 0.8 Watt at 12 VDC, and over 1 Watt at 15 VDC. An PSU-power box from an old computer is a good idea if You have. An very good building- info how to build this station can be find in SPRAT magazine #174 Spring 2018. Can be recommended by me, it is a small nice QRP box. SM2BYW. Jimmy

Very good job Peter... you seem like a very talented guy!! congratulations!!

[@RazorRadios]

Excellent work Peter!

Nice video 73

[@neiltan1939]

I just watched this today. Saw you video about the receiver alone yesterday. Thanks again for an excellent project and youtube video. 72 de wa4chq, Neil

[@raafatalheety826]

Thanks for you 73 from baghdad yi1hxh. can you ssb trx the same regenerative received with dsb transmit.

[@tonystephen6312]

Long live c.w. and regens!

[@tonystephen6312]

You could call it the - PURRFECT 40!

Is possible from LNA block made regenerative receiver from DRO ( dielectric resonator osc. ) on 10GHz band?

[@cx5fk]

Nice CAT 73

[@ksushchyk]

The regenerative receiver already contains a generator, I wonder if is it possible to turn it into a simple transceiver using the same coil for tuning both to receive and transmit?

[@jimmyjonsson2871]

Look at www.sk2au.org There You find an small article around this station.

[@Andre-PY4DR]

I just didnt understand exactly how the spot button works... if you could please explain?! That'd be nice !!

[@Dazzwidd]

All it does is run the transmitter oscillator and buffer stage for as long as you hold it in so you can listen to the transmitter frequency in the transceivers earpiece, enabling you to set the heterodyne correctly.

Best fo unknown from india

[@af4k]

Do you have a fixed circuit diagram or other details we can try to use to duplicate this?

[@Dazzwidd]

All that is required to build it is in the video. Just pause it and sketch the circuits out.

[@af4k]

YOU are SO LAZY!!! Sheesh! So now each person has to do this work.

Nice video de Yi1hxh rafat
