Hi Warren, I have carried out the M0BMU mods to my G0MRF amp. The improvement is extremely good. Not only does the PA run cool the output is greatly increased. I have run mine at 600 watts into du
Jim, One further question, can I tap the secondary per the original G0MRF design so as to have lower power outputs available by switching taps? Tnx & 73 Warren On Sat, Dec 15, 2012 at 3:55 PM,
Dear Warren, LF Group, It's a long time ago now, but... The multi-stranded winding was mainly used because it is much more flexible and so easier to wind onto the core. I used a salvaged LOPT core as
Thank you Jim, Stefan, Mal Good information! I will be putting it into practice soon! 73 Warren On Sat, Dec 15, 2012 at 3:55 PM, James Moritz <[email protected]> wrote: Dear Warren, LF G
Hi Warren, I use variable PA supply volts & can take power level to exactly what level I require. 73, Gary - G4WGT. -- Original Message -- From: [email protected] Warren Ziegler To: rsgb_lf_group@blac

Dear Warren, LF Group, It is possible to add taps to the output transformer for different output powers, although adding the extra bits of wire will tend to increase leakage inductance and make the c
Warren I have used Litz wire, for the application that you describe, plus other different types of wire around 3mm thick and it makes no noticeable difference since there is so little wire involved.
