• Ferrite Cores

A variety of 'High Flux' Cores, Material: FeNiCu


'High Flux' Core Size 1:
Outer diameter                    28.0 mm
Length                            13.0 mm
Inner diameter                    15.9 mm

'High Flux' Core Size 2:
Outer diameter                    28.0 mm
Length                            20.0 mm
Inner diameter                    15.9 mm

'High Flux' Core Size 3:
Outer diameter                    34.7 mm
Length                            12.8 mm
Inner diameter                    20.6 mm

'High Flux' Core Size 4:
Outer diameter                    58.5 mm
Length                            12.6 mm
Inner diameter                    34.0 mm


Ferrite Material FeNiCu is not a best specification for use on VHF / UHF as Materials 43 or 61 from NiZn show higher Impedance per size ... but it is sufficient even for demanding applications:

A single size 1 High Flux Core was used by the V31EME DXpedition on a 432 MHz 25 elem. Yagi lasting 3 moon paths with 0.9 kW in WSJT enabling even a CW EME QSO with this single Yagi.


Size 1 and 2 cores fit nicely on Cellflex LCF 12-50
(15.8 mm coax to 15.9 mm core inner diameter)

Size 1 and 2 on H2010 (10.3 mm coax)



These are surplus cores with material analysis but no other then the above
specification available. Plus plotted S11 Reflection in dB see here

• Cooling Bars & Fans


I occasionally get a 700 x 290 mm size heavy cooling bar into my shop.
Which I cut into 3 slices and offer them here.

QRO cooling bars

Used heavy quality cooling bars with are suitable for
QRO SSPA pallets on copper base layer (sandwich) up to > heat 1 kw dissipation with fans

• Size 290 x 232 +/- 4 mm x 92 mm
• Solid plate thickness 17 mm
• Weight approx. 9 kg or almost 20 lbs
• Plate surface fine milled and plane

Holes in surface are M5, outer fastening is M6.

A typical cut, grinded along but not fully, cuts will vary per individual bar.
Mid pieces have 2 cutted sides. These are used and cut to slices cooling bars.
I wish to make this tranparent an clear. I can mail photos on request so
you see what you get.
