Re: Trouble Oscillation qcx 40? #40m #alignment #problem #qcx40
¿ªÔÆÌåÓýHi, Gianpi The next thing to check is whether or not the volume control
thinks it's a volume control. Measuring from the three lugs on the
control to ground, one should check zero ohms to ground, the
opposite lug should check roughly 5000 ohms to ground (it's a +-
20% part) and the middle connection should sweep smoothly from 0
to 5K as the shaft is rotated. Volume control connections and an
occasional broken control were somewhat frequent problems
initially. I eliminated the problem with mine by putting it into a
box with a separate front panel, with the connections made with
stranded wire. My radio box also has 2 6-volt NiMH battery packs
in the bottom for 12 volts, and a charging/charge control
connector on the back. 73 Jim W4JED On 6/11/22 18:50, info@... wrote:
Hello James and thanks for your reply. To reply to your question yes, also with the volume control at zero the tone is loud and clear.... Increasing it, along the rotation seems it's vary just a little bit but always loud. I'm finishing my trip in Florida in 2 days, and next Tuesday I will be at home, and if helps. I could make a short video to give you more info about. Let me know in the meanwhile if there is something else to test it. Talk you soon. Best 73 de IK1TTD Gianpi? |
