15m Projekten - Zendontvangers

Klik voor vergroting15m CW Transceiver by PY2OHH
15m was always my preferred band, in spite of propagation going down, we learnt much from this project. I haven't indulged into making QSOs because I have little time to run the radios.

Klik voor vergroting15m Pipit QRP CW Transceiver by G3XBM
The rig is a simple direct conversion transceiver based around the OXO transmitter by GM3OXX with an SBL1 or similar double balanced mixer based direct conversion receiver.

Klik voor vergroting21MHz 1W SSB and CW Transceiver by JF1OZL
I made this new transceiver to operate CW and SSB with one box of machine. In Japan we can get from 10.595 to 10.695 10kHz step CB-junk crystals very cheap.

Klik voor vergroting21MHz 2W DSB transceiver by JF1OZL
About one year ago ,on 1998 my QSO friends said to me that he made this projects and he got 1 watt and he could make QSO with his local station.

Klik voor vergroting21MHz Transceiver by JA6UVF
Deze pagina is geheel in het Japans, maar met een beetje inzicht en de links onderaan de pagina valt er wel wat van te breien.

Klik voor vergroting3 transistor 21MHz CW transceiver by JF1OZL
I made CW 1W transceiver with only three transistor. I could make QSO by this machine with Saga, Asahikawa (domestic far distance city),and Indonesia and Taiwan.

Klik voor vergroting5 valve ssb transceiver for 21MHz by JF1OZL
See another explanation about ssb rigs in my homepage before you read this page! I will explain about the differences from the another machines.

Klik voor vergrotingCorner of the NO6 transceiver by JA6HIC
Even the HF band SSB transceiver that I made became the 6th unit with this transceiver, with the repetition of improvement.

Klik voor vergrotingTHE OTAKUCHI / 21MHz QRPp CW Transceiver by JJ1SLW
I checked my QRP note and found interesting note; PIXIE2 modification for the simple small transceiver to fit the case of "TAMAGOCHI", the popular virtual pet. BINGO, that's it!!
