qsl 3d models

His instructions can be found at http://www.qsl.net/wd4bis/DstFuse5.pdf. Crenshaw's design is based on the Radio Shack 270-1802 project box, but unfortunately, these boxes are no longer widely available and even when they are, users still face the...

A detailed guide is provided at http://www.qsl.net/dk7zb/Quadlong/4xoblong-2m.htm. Printing the parts using any material without support is possible. To assemble the antenna, you need one top holder, one dipole holder and three identical holders. The...

I do not recommend making clips for bars less than 30mm wide with these files.If you are looking for Yagi measurements, use the very resourceful website of DK7ZB:https://www.qsl.net/dk7zb/start1.htmWhat you need:For the Yagi:- Bar to mount the clips...

Steele. While this is definitely less efficient than a straight dipole would be, a 120 degree bend seems to provide a decent radiation pattern according to this article on qsl.net. Realistically, this a 3" freestyle quad -- it has more than enough...

All the electronic components and radio information were sourced from https://www.qsl.net/py4zbz/DCA.pdf. I modified some of the parts to make them easier to assemble, and adding nuts and bolts should complete it. I use a hiking pole as a tripod to...

The basics of using this design can be found here: https://www.qsl.net/py4zbz/DCA.pdf Specifications for the GOES Satellite Repeater Link, which orbits geosynchronously, are available at: https://www.goes-r.gov/users/docs/GRB_downlink.pdf A similar...

For reference, I followed this PDF guide to build my double cross dipole antenna: https://www.qsl.net/l/lu7did/docs/NOAA/DoubleCross_137Mhz%20AntennaMARTES.pdf Please note that the picture orientation gets distorted in Thingiverse's image viewer. ...If...

... are from an eBAY kit, search for "25 Pcs Set Multicolored Momentary Tactile Tact Push Button Switch Round Tact" also, this handy web tool by IN3OTD is useful to work out values using two resistors. https://www.qsl.net/in3otd/parallr.html

There you can also find [this PDF](http://www.qsl.net/py4zbz/DCA.pdf) on which my antenna is based. **This project is absolutely beginner friendly** if you are willing to put some effort into it. You might need to stock up on some gear however...

I used a camera tripod with the adapter shown here **Wiring Diagram** https://www.qsl.net/l/lu7did/docs/NOAA/DoubleCross_137Mhz%20AntennaMARTES.pdf Page 3 This will tell you the spacing, lengths and tilt. For NOAA, use: - 510 mm long antenna...

Today I'm excited to share my new case for the frequency meter designed by Wolfgang "Wolf" Büscher (http://www.qsl.net/dl4yhf/freq_counter/freq_counter.html). You can purchase the frequency meter kit for approximately 3 Euros:...

To utilize this design, you will need the following components: - 19mm OD x 1.2mm thick aluminium square tube - 10mm OD x 9mm ID aluminium round tube - As many "OpenEleV1" elements as required - 85mm of 22mm PVC conduit - Two 2x Choke.stl components...

Traps: 100pF, 4.9uH, 21' outer wire length\r\n\r\nBoth have 32' inner length, and are fed with 75ohm.\r\n\r\nMy goal is to make these traps using the coax trap design discussed\r\nlater in the chapter.\r\n\r\n# My Antenna\r\nUsing:...

These are the fastening elements and balun box with sealed cover for the DK7ZB dual-band (2 m and 70 cm) antenna https://www.qsl.net/dk7zb/Duoband/duoband_2-70_2-3.htm.This design has been made for the 20 x 20 mm boom.The tunable (+/- 1.5 mm) rod...

Duoband DK7ZB Yagi 2m/70cm with 2 Elements on 2m and 2 Elements on 70cm and one Feedpoint * 4,12dBd on 2m * 5,4dBd on 70cm Original design: https://www.qsl.net/dk7zb/Duoband/duoband_2-70_2-3.htm ----- VNA measurements taken in a home room - so they...

These precision guides were engineered to craft a Quadrifilar Helix Antenna (QFH) using an infinite balun design tuned to 137.5 MHz for the NOAA 19 Satellite as described below: Original Build Guide:...

Radio amateurs received QSL cards from Sputnik, which is a large size document available at https://www.thespectrummonitor.com/October2017TSM.pdf Here are some models of Sputnik:...

The antenna is based on this PDF file: http://www.qsl.net/py4zbz/DCA.pdf. Usually this kind of antenna is mounted on a roof or so, I designed it to be foldable so that you can take it pretty much anywhere and so that it doesn't take up too much...

Based on some research (https://www.qsl.net/ik6bak/dynamometer.html), it seems that users want from 5 to 50g. This all depends on the travel. To get to 20g, this means a spring rate of 0.37lb/in and to get to 50g, we would need a preload of ~7.5mm,...

These are just red and blue leds in a row and the naming “full spectrum” is a bit misleading.  If you measure the luminous flux 200mm beneath the led strips, you should get around 10.000 lux.Wago 221 splicing...
