Homebrew qrp HF transceiver. A description of my HF QRP transceiver. It is a multiband design. Output must be 5 Watt. I will describe the progress of its development. Tuesday, June 9, 2015. I have build the driver. It seems to work fine. I used a 1350p as variable gain amplifier. The signal out of the 1350p is amplified by a MAR2. Finally the signal is boosted to 10 milli Watt by a vhf power transistor that I happened to have. A 2n2219 would do as well. It works in class A. Friday, May 22, 2015. The band.CONTENT

Design and construction of a 50 MHz ssb transceiver. I was able to get a power module for 50 MHz for little money. It can deliver 20 Watt by 200mw input. This can restart the 50 MHz transceiver project that is on the shelve for more than a year. This pictures shows the current status. Working, more or less. It has been a long time after the last entry. Building was going on though.

Homebrew of a 144 MHz FM transceiver using PLL synthesizer. Sunday, October 3, 2010. On the web I have found a lock detector circuit for the 4046. I may build this someday. For Now I use a TX delay when repeaters are used. A good low noise preamp may help to improve sensitivity. The sensitivity is not bad but my yeasu is better. I hope the sensitivity can reach the same level. Then I can use the repeater in Bregen op Zoom PI3BOZ. Friday, June 11, 2010. Tuesday, June 8, 2010.
