I got many request from friend to listed full set of transceiver module on ebay. Its already pushing me hard to realize it as soon as possible. Really hard to worked with my “pneumonia” problem since last year, I didn’t smoke but its happen to me because the air conditioner bacteria. I have a full day jobs as a SAP consultant. Yes, It mean lot to do but I tried to build it as soon as possible, and this post is the progress.
Nothing new design of this BritX, its just some variance of famous BITX, I just added and replace some component exist on local, plus an audio band pass filter to make better audio in receiving. Everything is generic design but, my big job is to make all module work together in all band, its not easy, at least for me. After some PCB design, prototype testing, testing and again testing. Its worked now.
The transmit test result with 13.8v supply with dummy load after lowpass filter:
1. 160m 16.3Watt
2. 80m 17.7Watt
3. 40m 25Watt
4. 30m 20Watt
5. 20m 24Watt
6. 17m 22Watt
7. 15m 19.3Watt
8 10m 8.3Watt
Yes power out is getting low on the 10m band but its common for IRF510 mosfet. Using RD16HHF or RD70HHF will be a better with flat RF output on all band. For my friend thats already bought my RTC03 on eBay, please be patient this complete set will be list there soon.
RTC03 + BRITX + BPF/LPF + PA20
