Is it really hard? - VHF RX

om... Hello, I'm trying to find some simple receiver (or at least a converter) project for 440 or 144 MHz to build. I'm interested in CW mode. But there's nothing. Is it very hard to build something for 70 cm or there are another reasons, that I can't find anything? Julian, I do not know where you are looking. IF you have an HF transceiver there are VHF transverters available from both Ten-Tec and Elecraft http://www.tentec.com/Amateur.htm Elecraft will have a 440 transverter available in the near future http://www.elecraft.com/XV/XV.htm Hamtronics - VHF and UHF kits since 1962 Receive converter kits (less enclosure) are only $ 49 USD http://www.hamtronics.com/ Greg w9gb |

They sell kits for 50 MHz and up, up, up. http://www.downeastmicrowave.com/ Reliable outfit, reliable gear. They've been at it for many years. |

Julian,
No, it is not particularly difficult to build for 144/432 MHz. All you need are good low-noise devices, short leads and a little determination, which I'm sure you have plenty of. For starters, why not have a look at the simple 144 to 30MHz converter on this site - http://homepage.tinet.ie/~ei9gq/vhf_conv.html This should give you an idea of the style of construction needed. The only component that you may have trouble with is the overtone crystal but there are other ways of achieving the same end. 73 de Joe, G3LLV |

I do not know where you are looking.
Google of course, but it seems getting worse and worse... IF you have an HF transceiver there are VHF transverters available from both Ten-Tec and Elecraft http://www.tentec.com/Amateur.htm Elecraft will have a 440 transverter available in the near future http://www.elecraft.com/XV/XV.htm Hamtronics - VHF and UHF kits since 1962 Receive converter kits (less enclosure) are only $ 49 USD http://www.hamtronics.com/ Fine, but notice, please from where I am writing ( .pl is for Poland). The costs of shipping, a local tax and zoll payments will rise price about 75%. That's first notice. The second one is I want to build it myself. That's why I choose homebrewing group. |

We got good crystal producer here in Poland called Omig, BTW they are IBM supplier I think I'll find something. |
