Subject: sdr receivers DR1 (30 kHz -70
MHz) and DR2 (30 kHz-35 MHz) by YU1LM/QRP
Hello SDR
OMs,
As I promised 2-3 week ago I published SDR
receivers no SMT components based on 74HC4066 chips outstanding performances.
I had a lot of problem to publish new site version. Now links are OK but site
is not looking regular. I tried whole week to solve
problem but without success. This article is first part of three article
related to SDR receivers and transmitters.I used SDR
receiver from Alberto I2PHD as basic program for testing and measurements and
software is working really very good.
I wish
successfully realization of SDR receivers DR1(30 kHz-70 MHz )receiver without any coil and without
image rejection and DR2 (30 kHz- 35 MHz) with image
rejection also possible realization without any
coil.
