Wireless ham radio frequency counter

thingiverse

Frequency Counter Enclosure.\nIt is designed for use with internal 9v battery and any antenna wirelessly.\nA 6.5mm hole was drilled in the top case to fit a SMA type connector, an option I designed but not required.\nThe enclosure was tested on VHF-UHF antennas from RC and Ham radio supplies, producing best results with the largest one. The frequency counter worked great and precisely on HF, VHF and UHF bands with that same antenna.\nIf no antenna is available, a simple wire can be used.\nA wired version of this design is available here: http://www.thingiverse.com/thing:1160233\nWith these frequency counters, my 11m Ham radio is perfectly PLL aligned, using a simple multimeter and them.\nBOM:\n-4pcs M3x10mm and 4pcs M3x20mm bolts are needed for the box. Two 20mm bolts must be replaced with 25mm ones if the optional 35º angle holder will also be used.\n-Frequency counter board: A low-cost model (11€ as of now) works from 0,1MHz to 2.4GHz and displays 8 digits.\n-Switch type: This round switch has a 20mm diameter hole for mounting.\nThe enclosure is powered by a standard 9v battery with a connector.\nContribute:\nDonations are welcome because this design has taken time and effort, and I would really appreciate it if you found this useful. Your support will be appreciated and help improve future designs.\nMake a donation here: http://villamanydonate.blogspot.com\nThank you!\nPrint Settings:\n- No raft was used.\n- There are no supports in the design.\n- A resolution of 0.25mm was set for this print.\n- An infill percentage of 20% is specified for printing with PLA material.
