I haven't mounted it yet, but the fan has no noise itself. In fact, when I applied the voltage, I thought it was broken. It's very quiet, but it doesn't move a lot of air, either. I need to experiment

Yep. Good catch. TNX. john AD5YE

John, Your current statement is correct but in the last sentence of your previous post you said " The type 61 cores will take a few more turns than the 37 type cores for the same inductance. They have

Mike: The convention may have changed, but with Amidon and Micrometals, the standard convention has been for "FT" (meaning Ferrite Type) - 37 (size; ~1/3 inch) - 43 (meaning type 43 material. So a 1/2

John meant type 43 cores instead of type 37 cores below. Mike K5ESS

Yes that's also because the PTTsense line is missing. 73 Allard PE1NWL

Hi, Just saw that that you have used T50-2 cores. T50-2 will not work it is powdered iron core inductance will be very low use FT50-43 or smaller FT37-43 ferrite cores for the transformers.. FT37-43

Hi! Disconnect the 1uF capacitor at base of AF preamp Q4 and isolate if the whistling is due to audio stage or RF combined. 73 Rahul VU3WJM

Hi Allard: The PTT sense is not connected, I looked through the instruction must have the missed that part about connecting the PTT sense to make the scan mode work also I am wondering about top line

See this post: ??/g/BITX20/message/23973 ( /g/BITX20/message/23973 ) There are other grounds flying about meant to be return paths for signals. ?That's why it is

Ross, Normally when you press the Function Button 4 times scanning should start. The bottom line on the display should then read "freq scanning". Scanning will normally stop when: - the tuning pot is

First of all thank you for letting me in! i have already mounted the kit and i have troble finding where to connect the black wire at the moment it is not connected and seems to work ok

Indeed!

For the transformers in the BITX40Module, Farhan uses FT-37-43 cores.?? That is type 43 ferrite material.?? He has ten turns trifilar on those cores.? 10 turns on that core is about 34uH.????

Huseyin: What you are looking for are FT-37-43 and FT-50-43 cores. These are not powdered metal cores; they are ferrite cores. The red, yellow, and white cores are powdered iron; they work ok in BPF

Hi Allard: I really all the features of version 1.13, however I can not get the scan work, I have typed in all the parameters. When I go back to normal and try to start the scan mode nothing happens,

IMO there's no one "right" way. Either way is correct. I own several older rigs and they use different methods. For example Yaesu FT-901 has RX offset, Kenwood TS-830 has TX offset. But in all cases

I once asked Peter Parker directly through Youtube about that, where he said "power supply noise filter circuits may be your best friend here." I found that if you power the PA separately, you can tap

I'm pretty sure I made a check out to Dan's Small Parts. I don't think he has an email address. I had to use snail mail for everything and never did get a response by phone. That said, I wouldn't

I agree with your analysis, however by turning off the 12 volt supply I never have to be concerned with a faulty diode or any other problem. The 12 volt supply is not needed and it is a minor effort
