http://www.cebik.com/trans/ser.html Two short pieces of 75 and 50 Ohms cables will do the trick! You might also use UNUN transformer with 6/5 windings ratio or narrowband L/C match. Just keep a stron

ZX3S might have used one of the advanced logging features to spot everything he worked with hidden telnet window! We have seen side effects of FCC database instant access in the recent cases of WP2Z,

will volunteer to coordinate a WRTC in conjunction with that event. I hope you would not apply famous K4VX 1996 CA attitude "rules are cast in stone"! PY are doing a great job with an open process a
Take RG-59 75 Ohma coax, make 5 turns, extend inside wire for one more turn each end (7 altogether). Use coax shield for 50 Ohms input, inside wire for slightly un-balanced but isolated 100 Ohms outp

You also need two NPN transistors for COM TXD/FSK and RTS/PTT, 4 x 3K3 resistors, 2 x 10 nF RF blocking capacitors and stereo cable from AF OUT to line in! You can always make it more complicated wit
I often use EXCEL for log sorts looking for UBN. SH5 does that but produces too many potential errors. Google is useful lately with VHF hams appearing on deregulated HF, especially in RTTY contests.
cannot work you for credit in the contest! If one of you is calling, there have to be at least 20 more listening, and if I work one of you, I'll immediately have a pile-up of DX stations, and lose m
Jose, I like your professional examples of variuos cross checking and error rate levels as they are all linear :-) I did some log checking for multiops at K1B and 3V8BB and corrected obvious errors.
I asume this is a tech question but didn't notice any tech answer yet. ARRL test shows respectable IP3>20 dBm and that was soundly verified at 3V8BB on 40 m SSB with BCI. DSP CW filter was also fun t
<5KHz spacing which is what CONTESTERS need. In a contest, you're often <2KHz away from your nearest neighboor (on phone) and less than 500Hz away on CW. I experienced that radio congestion in Silic

W4ZV: Not American patriotism...American innovation. Nobody mentioned innovative Patriot radio "made in USA"!? Others are 1970 technology with "roofing" filters backtracking to 9 and 4 MHz respective
W4ZV: The 16 bit A/D you mentioned would not even allow the current dynamic range of the Delta 44 (24-bit) Minor difference being whole 60 MHz input range instead of 96 kHz VFO DC translation! 73 de
W4ZV: Close-spaced strong signal performance, phase noise, etc. in a single RX version should be better than we can imagine today. That good "single RX" has multiple frequency conversions inside! Eve
VK2CZ: I hope Montenegro has far better fortunes with proper recognition than the 2nd last 'NEW' country to come onto the ham radio scene. Specifically 'Timor Lorosae' or in English 'Timor Leste'. Da

W0UN: And at no time did any capacitors fail the 200 watt test -- or even get very warm. I guess you were lucky! I made W3NQN filters with a big VU mica caps for 2 kV and they all failed on 7 MHz and
