Why stick to 12v ?? Best efficiency will always be at higher supply voltages ....also more tractable output impedances. Alan G3NYK -- Original Message -- From: "Stefan Schäfer" <[email protected]
Hello Stefan,LF The tx is still on,freq.8.970.025Khz, power 100 Wat,but there is no radio amateur around,so the step to your grabber,(396km) is to big, henny pa3cpm 73's Hi Alan, In a few weeks i am
Hi Stefan, Ah I wasn't thinking of /p operation....you need a mule to carry more batteries :-)) Alan G3NYK Hi Alan, In a few weeks i am /p in EI for 7...10 days! I'm thinking about beeing QRV on LF w
Could these help in getting the efficiencies higher in LF amps? Granted, these are low power devices. Looks like they are on the right track. http://electronicdesign.com/article/power/Power-MOSFET-Kn
These FETs can be used as a very low-loss electronic switch in 12V circuits but are not suitable for a easy PA design (running at 12VDC). Maybe they are difficult to get. An alternative which is easy
Hi Alan, In a few weeks i am /p in EI for 7...10 days! I'm thinking about beeing QRV on LF with a "travel-equipment". This might be a 100m kite antenna and a LF TRX and a 12V PA running at up to 30W
