Tony, The V6 RXTX kit arrived here in Japan today. I will check all of the parts according to the newest BOM list. And will build it as soon as possible. Also...
Very good Hidehiko. Please let me know about any problems you find with the kit. I am still working on the low power problem but think I have made some...
Tony, I have been following the threads about the low power. Is it possible to breadboard and take a trsistor of the proper value and feed thru capacitor from...
Hi Loren, I am now getting just over 400mW from my RXTX board with the output sinewave looking very clean and the Q2 collector waveform looking like a...
Tony, I should have proof read my post. Should read...take a resistor of proper value. Loren If I do not dream then it can't come true! Loren Moline WA7SKT...
Tony, Thats great. I have been so busy with my space probe receiving system I haven't had time to build any of my Softrock receivers yet. Loren If I do not...
My guess would be NO. Without the filtering, you can't quantify the amount of harmonic power in the output. Without the filtering, you might show 2X more power...

Art, Thanks for comment. I realize it wouldnt be useable power..Its just that there was so much power loss I was wondering if it could be isolated to the PA...
Hi Joe, thanks for your replies ... performance ... The balun core transformer is no more part of the input filter The balance will also be reflected by stable...
... I listen on 40M with my SoftRock, many signals are at -100dB to -80dB those are mighty tiny signals that would barely move the S-Meter on the sound card,...
Good Afternoon All, As of this morning all v6 RXTX kits have now been mailed. Please check your kit and let me know if there are missing or broken parts. I...
... Mine arrived in NW Arkansas, USA on Monday afternoons mail. -- Cecil KD5NWA www.qrpradio.com www.hpsdr.com "Sacred Cows make the best Hamburger!" Don...
Tony, you really have a winner with this RXTX board. It's going together very easily and the construction is very straightforward. It IS easier to do all the...
From Terry, WB4JFI: As Tony says below, it appears he has fixed the low-power issue with the PA. It has taken me longer than I thought to clean my board up (I...
Terry, I've been out of touch for awhile and have lost track. Does this low power PA problem also occur with the TX stack version? That's the kit I have, but...
Hi Chris, Yes, the low output problem has also been noted by a number of kit builders of the prototype three board stack. The change will work for either the...
The only parts shortage in my V6 RXTX kit was one 4.99K resistor....not a problem. Pretty darn good for kitting all those up, Tony. The close spacing of some...
Hi Mike, It sounds like your SoftRock is working properly. I have a Delta 44 interface module kit that replaces the heavy cable and breakout box with a board...
Hi All Have not been able to download any of the PDF files. IE6 tells me not no connection to the server could be established. Has anyone else had this ...
Good Morning All, Several have sent me e-mails in recent days to let me know know what parts were missing from their v6 RXTX kit. I would ask all kit buyers...
Tony, Would please list the part numbers that need to be changed or turns modifyed so that these parts can be omitted during construction and not have to be...
Good suggestion Joe. On the v6 RXTX kit the following parts will be changed: R1, R7, T1, R21, RFC1, C26, C27, C28, C29, C30, L4, L5. On the prototype exciter...
To Bill Tracey & others: First of all, thanks for all your help getting PowerSDR working for the Soft Rock RxTx unit. I have been working with Tony on the ...
So, I sent this long note about how to adjust image rejection, and at the end, Yahoo asked for my password again, and the message never showed up here on the...
Good Evening All, A number of people have contributed to coming up with a solution for the low power output and out of spec spurious emission with the v6 RXTX...
v6 SoftRock kit order received since October 28 have been delayed due to stock of several components running out. An order for those components was received...
Sorry for yet aother post, but those of you whoe elect to use the 28.224MHz SMT crystal will probably need to put R50 on the board. I found that the...
Tom, What programming language do you use to write these programs? Loren If I do not dream then it can't come true! Loren Moline WA7SKT CN86cx Member: ARRL,...
OOOOooooooooopppppppssssss Man did we let that get by us. Terry this is not an overnight fix and will require more thought than a quick answer can provide. ...
