In the UK complete 3400 MHZ IONICA 15 watt(20watt) amplifiers are sold for about 45 GBP. If you place a request at ukmicrowaves@yahoogroups.com maybe somebody has one left. G3PHO describes here how he is using it in his transverter http://www.g3pho.free-online.co.uk/microwaves/9cm.html Best regards Frans PE1FOT Titel: Re:10W PA for 9cm Bericht door: Zlatko op September 30, 2010, 10:11:53 Halllo Frans!
Thanks for fast, nice and usefull advaice! I try to cach some IONICA on Friedrichshafen this year, but other was faster :'(. Toshiba PA was to expensiv for mee :'( In meantime I recived gift from Lorenz/DL6NCI ( FLM3742-12 ) :D , and now I "must" make PA :). That is reason that I am looking for papers... I find on internet some summary listing for Dubus. In Dubus Technick 2 page 200 is some article from DK1UV " 6W 3456MHz PA ". That is probably older from 1984. From this time I have some Dubus magazine, but there is NOT this article ! Is interesant that is article in Technick book and NOT in magazine ??? I am not shure wich active elements is used there. That was before 1/4 century ;D ::) Mybee somebody have documentation from old RF Module MT 3,4 Z 10 WA ( ex DL2AM ) 9cm PA. ::) Old DB6NT 9cm PA ( wich still sold Eisch ) is with 3 x MGF0905.. and not interested for me. TNX & WBR !!!! Zlatko Titel: Re:10W PA for 9cm Bericht door: Zlatko op Oktober 01, 2010, 04:13:18 finded ! by DK1UV was tube YD1060 :'(
