You may need to adjust the length of your antennas for best SWR, especially if you are not able to install them in a straight line. Otherwise they should work as well as indoor antennas ever do, so lo

If you are going to Hamvention you should go early if you can to catch FDIM. The vendors night is open to all; you have to register for the talks and banquet. QRPARCI is also offering streaming member

Now it Hz too much!

An EFHW works best if you have at least one tall support. A typical portable setup has the feed point near ground level (near the radio) and the far end elevated. You can also elevate both ends and ru

If it was long enough ago you may remember hearing the old 850 Hz shift RTTY, rather than the 170 Hz shift that is now usual.

I've been having a look at the HW-8 schematic. There are a number of things that would have to change in a modern kitting, in some cases to the extent that the result wouldn't really be an HW-8 any mo

By the time you have made all the changes suggested by AC9XH you no longer have a reboot of the HW-8. You have a rather different radio that should have a different name. I think the old school VFO wi

I'm not convinced that it would sell. First, there is the problem that air variable capacitors and reduction drives are expensive nowadays. You can use surplus components in a one of a kind homebrew r

Dave Crike's home page for his kits is at https://sites.google.com/nm0s.com/home/qrp-kits (NM0S.com does not currently resolve, though the Google link suggests that it once did.) The buying links ther

Yes. But most of that long list of prizes is only available to people who attend. Exactly ONE prize is available to people who pre-register but aren't there. OzarkCon sounds like a lot of fun. I wish

Those work well with most boards. They're not ideal for boards that have large components near the edge. I have one and often use it, but sometimes I run into a board where it won't work.

Companies can get permission to redistribute their QST reviews. But I don't know how much ARRL charges for the privilege. I wouldn't expect it to be steep for a ham club like 4SQRP.

The Internet Archive has a number of old Callbooks, the newest one being from 1997: https://archive.org/details/1997_Radio_Amateur_Callbook/1997_Radio_Amateur_Callbook_District_0/page/n127/mode/2up Th

Likely not for the same reasons though. Grainger sells primarily to businesses; they were probably having a big sale on that Weller soldering iron because it's being discontinued. They have other mode

Frequency response of a filter won't tell you the entire story, though the worst offenders are well in the past (and good riddance). One reason that many SSB radios from the 60s and 70s sounded bad wa

The only single band one for 40 meters that I know of that is available new right now is the MFJ-9440. Each model is a bit over $300 (prices vary by band for some reason), which feels like a lot to me
