Homebrew equipment by JR3XUH - More than 40 of equipment; rigs and test devices.

144 MHz preamplifier with BF981 - Design of a preamplifier for 144 MHz with 1 dB NF and 23 dB gain using BF981. This amplifier is using a low cost silicon MOSFET (BF981 from Philips) to give more than 20 dB gain with around 1 dB noise figure on 2 meter.

Low noise preamplifiers  ^pop - Lot of projects of preamplifies from HF to VHF and UHF by yu1aw

U301 FET preamplifier - This FET preamplifier has been around for almost 25 years. It is extremely reliable and can handle several watts directly into either the input or the output without failure.

23 cm GaAs FET preamplifier - On 23cm the best way to obtain a good RX-sensitivity is to use a GaAs-FET in the front-end, since these devices show very low noise figures.

Receive only processing equipment - One of our most popular products, receiving preamplifiers are used for achieving top signal band performance in competition operating, low noise longwave reception, repeater applications into the UHF region, or lab use
