Re: BITX QSO Afternoon/Night, Sunday, January 21, 3PM/7PM Local Time, 7277 kHz in North America, 7177 kHz elsewhere
Here in mid-west look for us on
7178 and 7278. South of the border stations on 7177 and strong
carrier on 7277.

Well worked a few stations even a new General /AG Larry in VA
Also got K9ABL David in KY
I will try and get back on for the 7pm but might be a bit late.

Not hear any stateside on 40m i did try contact with W1NA on 3,799 MHz? with my bitx on 80m with 10w but I not make it Chris G0WFH?

Mic Preamp install, bias resistors
#ubitx
HI Group.
I am about to install an SSM2167 Pre-amp, Should I remove the bias resistor R60(4.7k) and then re-install post amp at say a 2.2k for the lower 5V the amp uses?
IIRC, the SSM2167 Spec sheet? mentions a 2.2k bias resistor for electret mics...
Thanks in advance.

Re: Mica Cap replacements for WA2EBY Filter?
I used this paper.??
You print the image in reverse to scale on that stuff, iron it to the copper clad, and then soak in ferric chloride. Getting a good etching mask is where all the trickiness is. I think lots of iron pressure and heat really help.

Jack, W8TEE
I just etched the filter board! Not a perfect toner transfer, but not too bad. The traces are solid and pass the beep test. :)

David N8DAH can just make you out about 2x3 at best. Heard K9ABL much better. Poor east west prop right now from Barrie.

So, finally I did it - BITX40, diode D& blown (nice light and smoke)
It is "off the shelf" radio - I made it few months ago - and now I take it to upgrade software etc..
Power on - and smoke. but raduino still works.
so I disconnected power connectors from mainboard, rechceked polarity - all OK. Turn on - Raduino is OK.
I dedoldered diode, reconnected power to mainboard - all OK.
Just courious - what happened?

The issue with small speakers for communications use is that you want something quite different from HiFi speakers in several aspects.
While I use headphones exclusively for operating, I do like to “read the mail” (listen) while working in the shop.?
The key is proper frequency response, good absorption of sound off the back of the diaphragm to limit distortion caused be the reflections hitting the diaphragm, and proper strength magnet to control the voice coil movement.
For our communications headphones we build a metal frame, Mylar cone driver with Neodymium magnet that provides high sensitivity but huge dynamic range, 200-6000Hz response to cut off noise that is of no value and quite fatiguing to listen to and the Mylar cone (diaphragm) is not disturbed by moisture and temperature changes to give excellent control over the voice coil positioning.
I could make available to the community a kit with a 50mm, 32 Ohm driver, foam dampening and mounting hardware (3mm standoff’s, Screws, lock washers and nuts) 2 mounting points, if enough people are interested. I can make one and show how it could be installed.
?Output can be attenuated even as these are easy to drive and the uBITX has tons of output.
Dave WI6R Google “radiosport headsets”?

Think you have to take into the baffle effect of the panel that its mounted behind, mine sounds good, saying that I did plug it into my Yaesu SP-8, decided that the 3inch speaker was far better.

Make sure the brand is mega watt and not the cheap Chinese knockoff. The cheap ones don’t have proper RF filtering and they use cheap fans.?
The fan on my mega watt 26amp was noticeable too and I complained. They sent me a fan that was quieter, less cfm’s but it did the trick. And I’ve been using it with a 100W radio doing digital modes and it hardly works up a sweat.?
