mcmichael: Super Range Portable four: Demonstration

I don't have a suitable Lead Acid Accumulator (yet!), so for LT filament I have two sets of two 3500mAH NiMH combined with 1N5818 "dropper diodes" which under load gives a reasonable voltage. Fully charged the NiMH terminals are about 1.4V (2.8V for two). The recommended end point is 1.1V (2.2V). On load the fully charged cells deliver slightly above 2.2V (they should not be connected to charger while in the Radio Set even if a Lead Acid).

Here is the Daytime Reception of LW on Youtube in the Midwest of Ireland of RTE1 and BBC R4. It also gets one French station quite readible on Daytime LW. I will add the MW at night as we only have one low power  MW station at the other end of Ireland. Few radios pick that up here!

Replica Winner 120 (80 "budget" Alkaline AA cells) and 9V GB (6 x AA cells) packs are used.

Poor lighting, but after Dark, so the UK MW in the Midwest of Ireland

Demo on YouTube at someone else's house on the City outskirts.
