80m ARDF enkelsuper vossenjachtontvanger door PAØNHC
Radiovossen jagen gebeurt vaak met 2m-apparatuur. Maar een echt goede, goedkope en kleine 2m-vossejachtontvanger bouwen is lastig.

80m Band Direct Conversion Receiver by DL2YEO
The first differential amplifier inside the NE592 is used in this application (unlike it's normal function) as a symmetrical mixer.

80m DC Ontvanger door PA2RF
De DC ontvanger heeft de prettige eigenschap, dat met een minimum aan onderdelen een maximum aan resultaat te bereiken is. DC staat in dit verband niet voor gelijkstroom ( " direct current" ), maar voor Direct Conversion.

80m HF Receiver door GØUPL
Sneak preview of the receiver. Construction uses the "ugly" method and the receiver is currently unfinished.

80 Metre Receiver by EI9GQ
This 80M receiver design includes the necessary switching to allow the SSB filter and first I.F. amplifier to be used for transmitting. The receiver stages from R.F. input to speaker output will be described in detail below.

80-meter Regenerative Receiver by K9PPW
I included this schematic of one of Bob's homebrew projects, an 80-meter regenerative receiver that uses only TWO transistors. This receiver is quite sensitive. The goal here was to make a receiver that has SMOOTH regeneration control, that doesn't "pop" into oscillation and "hop" frequency or pull as the gain is increased.

80 m SSB/CW superheterodyne ontvanger door PA2RF
De hier beschreven ontvanger is er één gebaseerd op het superheterodyne principe. Ontworpen om radiosignalen uit de 80 m amateurband (3.5-3.8 MHz) te ontvangen werkt deze ontvanger met een relatief hoge MF (8.867 MHz).

80 meter vossenjacht ontvanger door PE7M
In dit artikel beschrijven wij de 80-meter vossenjachtontvanger zoals wij die hebben gebouwd op de VRZA radiokampweek 1999.

Home-Brew Regenerative Receiver
I acquired this piece of "junque" some time ago. The tubes are a 6V6 used as the regenerative detector, and a 6SN7 used as a dual triode audio amplifier.

Integrated Circuit Receiver by SMØVPO
The CA3123E is a simple single superhet receiver and is designed for operation in the medium waveband. I have used this IC up to 4 MHz with 100% success.

'One Chip' Receiver by GØFGI [G3YCC]
The circuit is of an 80 meter band one chip DC receiver, (excluding the AF stage). As you can see the design utilises the NE602 as VXO/mixer. It is economical with components.

Regenerative TRF Receiver by EI9GQ
I have received several e-mail messages from people looking for a design for a very simple receiver.I decided to use a computer sound card as the A.F. amplifier for a simple TRF receiver.

Rescaling the MRX-40 Receiver for 80 Meters by K7SZ
Last October I found myself on a flight to Tyndall Air Force Base in Florida ... Before leaving, I put a request on the QRP-L e-mail reflector for ideas or designs for a companion receiver kit to match the NoGANaut 80-meter trx.

Signal Frequency Beat Frequency Oscillator by VK3YE
The days when you could listen to amateurs on a simple shortwave AM receiver are with us again, thanks to the development of this one-transistor, frequency-agile signal frequency beat frequency oscillator.

Small 80m direct conversion RX by VK2ZAY
I used the same unit that I built as a prototype for the LO in this project. I've added a buffer, mixer, an AF and RF amp of my own design, to make a very usable and quite compact 80m receiver.

The AGC-80 by KE3IJ
Here's a Regenerative Receiver project that I designed for the 80 meter Amateur band, but which can also be used in a wider-tuning configuration that covers approximately 3 MHz to 10 MHz, for Shortwave (World Band) listeners.
