Speakers arrived the other day. Supposed 2" speakers are more like 1.5", 40MM. 4Cm. Have not tried one out for sound yet. Wayne WA2YNE

Cheap way to have slow and faster tuning with an encoder is to have a two-size knob.? Smaller part tunes faster and larger part does fine tuning.? Those with a metal turning lathe can make a

I think I found a good tapping point. C215 before the filter and shield to ground. C216 seemed like there was a lot of noise, I don’t think it was more signal, just more noise. C214 looked ok but

When used in matched pairs, the dots should be together.

I bought a new tank. I only use ammonium persulfate. glenn

Arghghh..Glenn? Jaycar or Tricky Dicky strikes again.? I saw some very nice tanks built by a guy called Adam Seychell in Melb for personal use. you use ordinary glass say 4 mm think for all the

No.? The dot is likely for matching or grading. Allison

Hi Fabian, I think for sure your BFO is set wrong.? From reading other people's posts on this forum, it seems like the BFO is not always set correctly at the factory.? And also it seems like it is

Tom: In many cases, the steps/rev is a function of cost. Also, mechanical encoders are less expensive than optical encoders and optical encoders usually don't have the feel of "detents" as you turn

Buffer board for Si5351 now etched and assembled.? Fitting to come. The sharp eye among you will see the left side buffer chip has a short between two pins, now cleared. Parts are all 'small', caps

Would tapping across c212 do the trick or maybe c210 so I’m not connecting directly to filter. This looks a lot like my commercial rig except there is variable inductors? Tuning cans before the

Yes, the filter is working. I always thought it odd to put the tap there.? The RTLSDR does not need the gain and its just the wrong spot. It would be better closer to the antenna but then gain the

Is it possible to replace the stock encoder with one which tunes more steps per revolution? ?If so, any recommendations? 73, Tom ?W1EAT

Hi Fabian, maybe you can try to use attached Memory Manager config file. It's the one from my Raduino with out of the box settings. ?I haven't changed anything. You can try to load this one and see

I answered in my post about this but didn't want it to get lost and buried so am posting this??separate.? I posted the schematics in the picture (Sunil's AGC folder) and the instructions in Files

Thanks Ashok, I'll try it Andy

Ok thank you! Have you read my describtion of the last receive test? When you read the part of i say bad ssb and much bad AM signal sounding then what do you think about? Is my only issue just the
