So you'd like a radio, but you can't afford a $1300 IC 7000. What's the alternative? Build it yourself!
This is a research page for kit radios...
manufacturers, designers, and kit lists
- Homebrew RF Test Equipment and Software
- http://www.danssmallpartsandkits.net/ hard to find parts
Design our own kit
It would be neat to have a cheap fixed frequency FM receiver tuned to the repeater that we could loan to new members.
- receive only
- fixed frequency(s)
- PL tone squelch?
DSP transceiver project
- http://www.tracey.org/wjt/temp/picastar-all.pdf 20 part article containing all art work
- http://uk.groups.yahoo.com/group/picastar/ yahoo group
potential narrowing criteria:
- must do both CW and SSB
- must support multiple bands or be very cheap
- xmit > 1w ?
- two dollar regenerative receiver
- QRP three bander: QST 10/1989 ARRL handbook ch 30 fig 2 $12.50 per board from FAR
- KK7B's Micro R2 receiver, QST Oct 2006 pg 28
- CW or SSB, 100khz in a selected band
- claims to be a better design, $80 for kit
- No Excuses QRP Tranceiver: QST 12/2002 pg 28
- home brew UHF D-STAR (does not work)
- MicroT2: A Compact single band SSB transmitter QST Dec 2006
- HiMite / RockMite http://smallwonderlabs.com/HiMite_docs.htm QST Dec 2005
- low power PSK31 tranceiver
- http://zao.jp/radio/sft66db2/ (single band, no dsp)
- http://softrockradio.org simple SDR kit, appears to only cover CW portion of the bands
- Firefly 20m and 30m cw optimized
Reasons for buying a kit instead of copying it and building it
It's a kit, you can make it yourself and just go get the parts, right? Here's why you'd want to buy a kit instead:
- Custom enclosures are cheap when mass produced; otherwise you gotta fit it in a box you found somewhere
- Some parts are hard to find, or hard to buy in single quantities
- Surface mount parts are more expensive to ship in single quantities than to solder on a PCB and ship the PCB.
- PCB's are hard to make. Yes, we can mill them, that works for two layer boards. But most people can't do that, and multilayer boards are still out of our reach.
