80m Projekten - SSB Zendontvangers

Klik voor vergroting3.5MHz 10W SSB Transceiver by JF1OZL
In week day I operate 7MHz CW on my shack. But in these days, on the 7MHz , my signal skips out from Japan and I can't contact any station after 10 o'clock. Therefore I decided to make 3.5MHz SSB and CW rigs.

Klik voor vergroting3699 kHz LSB transceiver by OH1TV
This project is real but at the same time a joke. In OH-land the rag-chewing channel on HF is 3699 kHz LSB. Many people meet there every day, sometimes all day. And more are just listening. In fact those hams would not need more radio than this single channel LSB transceiver for 3699.00kHz.

75 Meter Ham DSB Transceiver by KE7HR
With the success of the 75 and 80 meter ham band experiments that I had done in the past, I wanted to have a simple and inexpensive transceiver to bring underground.

Here's 75 Meter QRP SSB Transceiver. In general, the transceiver switches the 4-element 1500 ohm xtal BPF ends between the inputs and outputs of the two SA602s to reverse the signal flow for R/T operation.

Klik voor vergroting80m DSB transceiver by PE1JPD
It is a DSB transceiver with an output of 5W. It is build around 8 noval tubes of the EF/EL series using a lot of material from Amroh, a form manufacturer of electronic components in the Netherland.

Klik voor vergroting80m SSB & CW QRP superhet transceiver by S56AL
The 80m SSB & CW transceiver design is based on an already proven concept used in ATLAS amateur transistorised transceivers from 70's.

Klik voor vergrotingExtra simple DSB 80m Transceiver by ZL2BMI
Back in the mid 1980’s I designed and built various 80m DSB transceivers. Some of these were initially published in the NZART magazine; “Break-In”.

JUMA-TRX1 is a direct conversion HF transceiver based on the previous JUMA-RX1, JUMA-TX1, JUMA-KEYER1 projects. It is driven by a stable DDS VFO and has the following features.

Klik voor vergrotingNano - The Traveller’s Rig by KANG. K. P. S
Lately I had a feeling of necessity of an 80 meter portable rig for use during traveling and camping that proved to be the main impetus behind the development of this little transceiver for portable use.

Klik voor vergrotingSimple QRP transceiver for 80m SSB by OH1TV
I have many rigs for QRO and QRP, old and new. But still I wanted to build myself a simple SSB rig and feel the homebrewers satisfaction, when on the air with such a rig.
