I restored one last year. Recapped checked resistors and transistors. I had a dirty micro switch for the DOT, turned out to be dirty cleaned it and it works great. Case paint is in mint condition.
Great video, Jeff! I just restored an HD-10 for use with a DX-60 and HR-10. Vintage gear is my niche in the hobby. 73, Mike K 0 Collects Radios eXclusively
I built one of these back in the late 60's and used it daily. I connected a Brown Mfg. Co. dual paddle key to it (the internal key leaves a lot to be desired). I still use it today. 73 Magazine article here: www.nostalgickitscentral.com/heath/73-index/articles/HD-10-3-66.pdf
Do you know if I can use my Heathkit Model HD-10 keyer with a more modern transceiver? I have a new Yaesu FT-DX10 - I am afraid to connect it - not sure if the voltage coming off the Heathkit keyer is incompatible with the modern solid state rigs???? I also have a Yaesu FT101EE - and it works great on that rig. Any help appreciated!!!!!! Ron WB9EGG
The keyer should not damage the transceiver - it's more an issue of whether the transceiver will damage the keyer. The HD-10 works with with grid-block keying or other transmitters that use negative bias, provided it does not exceed 105 volts at 35 mA. The FT-101 models use grid block keying so it works in that case. The FT-DX10 is a modern transceiver and likeley not using negative keying as it is a modern transceiver. It might work if you reverse the polarity of the leads from the keyer.
@@jefftranter Hi Jeff, Thanks for this quick reply and information! When you say "reverse the leads" - do you mean to use the ground as the "hot" lead and the keyed line as the ground?? My Yaesu FT DX10 uses a 3 contact 1/4" male - it wants the tip to be the DOT and the ring to be the DASH, and then the sleeve to be the COMMON. My manual says key up voltage is +5.0 Volts DC, and keydown current is 3ma. Does that tell you anything further as whether it can work or is compatible?? Ron
@@RonPurser Yes, you would use the ground as the hot lead and keyed line as ground.However, if the ground line of your FT DX10 is at chassis ground , this is probably a bad idea as the keyer's chassis will be connected to the rig's keyed line and not ground. Another option is just to use the paddle of the HD-10 and use the FTDX10's internal keyer, but it looks like that would require some rewiring of the HD-10 and it would then no longer with the FT101EE.
