Make your own dummy load
Had a friend (we wont name him) pop into the shack today with a beautiful TS-520 in almost mint condition. It even had a DG-5 digital readout. Only problem was he couldn’t get it to transmit.
After a short time i asked him if he had noticed the SG on/off switch on the rear panel. Nope was the reply. Well there’s the trouble it needs to be ON to supply power to the screen grids.
After much laughter and a generous amount of joking i asked if he had a Dummy load to use to “tune up” the old girl prior to transmitting. No not yet was the reply.
I told him i was sure i had a good design for one somewhere and proceeded to search through old AR’s and QST’s until i found just the thing.
A great design from Ross VK2KVV that was published in the Feb 1999 WIA Amateur Radio Magazine. Its called the HF-MT Dummy Load . HF-MT stands for “High Frequency Milo Tin”.
I remember making a similar one years ago and this is just the thing to get your home brew juices going.
I present it here in PDF format for your enjoyment and education
