#3 sweeper version. this is good dave n4lkin

Tough for many to work with because they won't. Homebrewers are going to have to? learn a few SIMPLE and CHEAP tricks to solder devices like this. I've been using this process for several years

You can always buy the board for a little over 17 Euros.

Fantastic work, Nik. I’d definitely be interested in 2 or 3 smd or th boards, unpopulated. I’m curious to see how the 8307 fares. In my experience they need a fair bit of shielding. 73 de

or maybe just a front panel knob to do "power level"?? Heathkits had one of those..... In this case, it might have to be RF, but if you went with a composite logarithmic, stepped the gain of the TX

The best solution would be to get the transmit power amp chain to behave, giving uniform power out across the bands. Failing that, the PE4312 attenuator would be good, though a tough package? for

I will rattle through your kindly provided steps once I have a sleep. tiredness and absent mindedness got me into this pickle in the first place. On that note a VERY BIG THANK YOU. And I will get

If locking were accomplished in software then one would have to press the encoder and could shift the frequency. If the button on the ground wire will work that seems like and nice solution. 73,

The AD8367 is more than twice as expensive as the PE4312, though the AD8367 datasheet does show how to implement AGC with it using 2 additional chips.? So if you want to include AGC with programmable

It could also be done in software. Jack, W8TEE To: [email protected] Sent: Tuesday, February 20, 2018 2:38 PM Subject: Re: [BITX20] Replacing the Rotary Encoder #ubitx If one wanted to lock

Thanks That seems to be better. So all one would to even out the power is to change C93 and C94 and put a a 110pf across T11 primary. Thanks Lawrence

SV1AFN makes some great products That’s all I can add here lol Joe, KD2NFC

Yep. There is a similar AD8367 that has a larger attenuation range... 45dB that can work too. Just need to add it to the list. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ

Hi Jerry I am happy for others to use the Gerber's, but idd say let me actually order and test a batch first, then you can go crazy, just leave my callsign on the board.... Otherwise I am happy. O am

Excellent find! Power into Q90 of the uBitx is less than 1dBm (best guess, perhaps -7dBm?) and at 50 ohms. The stage at Q90 might have a gain of 15dBm, I'm not sure without checking my simulation. So

The style is KF2510.

OK, stupid question time.? Let me preface this by saying that although I'm a EE, I've only recently gotten my Technician's license, and I've done nothing but digital design since taking my

If one wanted to lock out the rotary encoder, like some rigs which have a lock button for their tuner. Could one just break one of the encoder lines with a switch, say the ground wire, and get the

Ordered 12/22/17, received PayPal shipping notice on 2/17/18, received uBitx this morning 2/20/18 (St. Louis, Mo area).? Took one day processing in Cincinnati. Dave, W0DF
