Cheap Broadband Preamp Boards
Hello. I was wondering if anyone has any experience with the cheap broadband preamplifier boards that are being offered for use with the RTL-SDR dongles. I'm thinking they may be an inexpensive option. Thanks.

James, The broadband preamps can easily overload from things as diverse as the neighbours door openers to LED lamps. What you need is a two stage amplifier with adequate filtering to just the two meter band. There will be very few such amps on aliexpress. SSB use to make some good ones. If you have basic soldering skills, you can take a stab at the preamps from 80s ARRL Handbooks (About the time when handbooks were full of things people could build rather than gawk at). - f
