Send in your QRP Pictures!
|
Hi everyone,
Right now the group's header image is just the default Groups.io image. I'd like to change that up! Send in your favorite picture of your QRP rig or QRP related activity. You can put it in the QRP Pictures folder in the Files section or add it as an attachment here. Once I have a few I'll make a collage of them and make that the header. Thanks! -- Ryan Flowers W7RLF

Sent some pictures of the Ugly Weekender Transceiver I built in 2014. I'd like to have more projects to send but I have no photos of them (for some damn reason). I want to do more things with tubes. Ed AE7TE On Thu, Nov 7, 2019 at 10:28 PM wb6ogd <garywinblad@...> wrote: Working now, thanks! |
¿ªÔÆÌåÓýEd, If you want to do more things with tubes you have lots of choices
but may I suggest building a true clone of the PARASET, or
Philmore NT-200 Novice transmitter.? These won't be fast or cheap
if you want a true clone but they are fun to build and use.?
Besides they hold lots of history.? There is a lot of support for
the PARASET .? The NT-200 puts out a very usable signal.? Both for
the most part can be reproduced with parts after doing some
scrounging.? Refurbishing a transmitter such as a Heathkit DX-60
can be interesting and fun and actually cost you less then doing
one of the two above suggestions.? Here you would replace poor
tubes, replace out of spec resistors and caps such as tubular
paper ones as well as the electrolytic capacitors.? Then clean the
radio, controls and switches.? Sometimes repaint transformers and
covers too.? Lee, w0vt? On 11/8/2019 10:22 PM, Jon Edwards

You guys are awesome- thanks so much for the support in uploading your photos. Six photos gave me enough to build a header banner for the group. Go to the groups main page to check it out:
/g/qrptech Feel free to keep uploading, the more the better! It might be cool to have a builders gallery too, and they can be used for that. -- Ryan Flowers W7RLF

Lee, Not really interested in refurbishing. I want to make something my own. This is almost like the OMs who answer my homebrewing questions with "why not just go buy ___?". I know people mean well but I would rather make a boatanchor than buy one. Actually, I've been making some mild steel enclosures to build skill for my eventual 50-lb radio. I'm wanting something more capable than a one-tube oscillator-amplifier. At very least, a MOPA transmitter. I'm also not going to buy FT-243 crystals (too rare and too constricting). I'm either going to figure out a VFO, or I'm going to drive the oscillator stage with a DDS generator. At very least, I'll buy some QRP crystals in the HC-49 case, 3D print or scroll-saw some cases, and build some up that way. If I were using smaller crystals, I'd limit the oscillator stage to 45-75 volts, meaning the crystal heating should be low. Right now I'm finishing up a 6SN7 twin plex receiver. It will do until I can make some kind of superheterodyne rig. A full-blown phone transceiver might be a bit much for working in tubes. I'm not sure what I want to do but I get very little time to build, let alone operate, these days. Ed AE7TE On Fri, Nov 8, 2019 at 9:22 PM Leland L. Bahr <w5drc@...> wrote:
