Rough bunch....Dang! oughtta see me type after 3 or 4- 807's Better yet, rip cw....lol 73 all Dean

Whoops, had a type-o on my web page. The Chinese rigs are coming with 7.023 crystals. I see some of the Epay places list them going from 7.023 to 7.026 but with HC49/s "rectangular AT Strip cut"

You have got to be kidding - the webpage says the crystal is a 7027 and states that it in the *extra* class band. Extra class is below 7025 kHz, so I don't believe the author of that webpage

Looks like you saw many of the same things I did during the build. http://kc9on.com/ham-radio/chinese-qrp-kits/ One thing I can't check was the output. Would be interesting to see if a LPF is

To get a feel for the value, go to EBay and search for J-37, J-47, J-38. In my mind, if I used this key as a novice or one like it, which I did by the way, and I would like to have it for old time

Don't forget: Tonight is the July SSS. Get on the air from 7:00 pm until 9:00 pm (Ozarkcon time). Show everyone how much better your CW is after Field Day. The rules were in a previous email and

I fired up my Chinese Pixie last night. The receiver is surprisingly sensitive, with MDS of about -115 dBm. The sensitivity comes at a price, though. The 5 kW AM station 20 miles up the road from

Wayne, Way to go my friend!!!!! A very good radio tale of victory!!! Nice picture with the story —— it should end up “Somewhere”:-) cu es 72, Bart W0IIT Pittsburg, KS 4Sqrp=#72, FP=#11,

The July sprint is this coming Wednesday evening local time (July 15th, EDT - 8:30-10:30PM, CDT - 7:30-9:30PM, MDT - 6:30-8:30PM, PDT - 5:30-7:30PM), which translates as Thursday, July 16th, 0030 to

Don't forget (like I almost did)! The Second Sunday Sprint is this Sunday, from 7:00 - 9:00 pm CDT. We need lots of activity, to make up for the poor showing last month due to the weather. Let's

Converting an RM][-80 to an RM][=60 is on my to-do list. There are some things to consider. The main consideration in addition to frquency accuracy and stabiltiy and the offset frequency. The

Curt, 60m is very popular with SOTA ops for NVIS mode contacts. Here in the UK, The G-QRP club and Kanga offer crystals for 5MHz. I know that some of our frequencies are the same as US

Add a mixer - and rather than crystals, use a DDS controlled by a Raspberry Pi. The RF section from the mixer to the final output is no more difficult than for more simple rigs. 60 meters

I finally got back to the workshop last night and built the Chinese Pixie I'd bought a couple months ago. Here are my observations: 1. The parts supplied did not match the schematic. Too many

Interesting idea -- but it has its challenge -- I can't imagine that an appropriate xtal exists, that precisely matches one of the allocated 'channels' in this band, if indeed one can be found to even

How about a single frequency rig for 60 meters? I wonder if a pig rig v2 could be built for 60 meters

My ISP is acting up again today (Mediacom, the company we love to hate). So this is the second try, hope it gets thru. I lumped last nights and this morning's checkins into one email so
