The most simple way to reduce the ...Hello Richard, <br />The most simple way to reduce the power of a Rig with a fixed power, is to build an attenuator. I have developed power attenuators for an input power of 500 mW to 5 watts. An attenuator of 10 dB can reduce you power from 5 watts to 500 mW. These attenuators are build with good available carbon resisitors of the E12 series.<br /><br />If you build the attenuator with <b>9 resistors</b> (1.6 W with resistors of 1/4 W), but you use <b>1/2 W</b> resistors and <b>CW</b>, then the maximum power will be 1.6 x 2 x 2 = 6.4 W<br />Pse see: http://a29.veron.nl/pa1b-06.htm#att10<br /><br />73,BertBert, PA1Bhttps://www.blogger.com/profile/14064917598289627232noreply@blogger.comtag:blogger.com,1999:blog-6578979601685683195.post-71142730787719462592011-12-04T19:09:51.064+01:002011-12-04T19:09:51.064+01:00Hello Richard, When I started as a HAM, I used a h...Hello Richard, When I started as a HAM, I used a homebrew 40 mtr QRPp transceiver with 500 mW and worked many European countries, with an Inverted Vee.<br />Recently 15 m and 10 m are giving much better propagation. This is great fun. On these bands you can use a simple wire antenna. I have made many normal and contest QSO's on holiday using wire antenna's of 10m or 20m, together with my very simple homebrew holiday tuner.<br />And please remember: Propagation is doing more than any antenna. hi<br />Good luck in QRP, 73, BertBert, PA1Bhttps://www.blogger.com/profile/14064917598289627232noreply@blogger.comtag:blogger.com,1999:blog-6578979601685683195.post-61104310520809740392011-12-02T22:51:37.209+01:002011-12-02T22:51:37.209+01:00I have QSOed several QRPp stations recently.

An increasing amount.<br /><br />Right now I can't go below 5 watts but am expecting a used SW-20 rig to arrive which will get me below my current QRP power.<br /><br />Congrats on your contest results.Dickhttps://www.blogger.com/profile/10984094559146508871noreply@blogger.com
