700/800 MHz Public Safety Band Penetrates Buildings Well!

 In a response to my post in the HamSCI (Ham Radio Science Citizen Investigation) Google Group, N8SBE mentioned that 700-800 MHz is quite useful for first responders as it penetrates structures well. Within building coverage is of vital importance to firefighters. According to him, building owner is required to place repeaters inside to assist coverage as well. Skimmed through our National Frequency Allocation Plan 2022 and found that 614-890 MHz has been allocated for fixed, mobile and broadcasting services. 806-811 MHz frequency and 851-856 MHz paired frequency has been allocated to Public Protection and Disaster Relief (PPDR).


There are also other frequency bands mentioned for PPDR applications. I presume that it will correspond to the first responder use mentioned by N8SBE. In the introduction of NFAP 2022, it has been mentioned that before any part of the spectrum is put to use in India, a licence is required to be obtained from the Wireless Planning and Coordination Wing (WPC Wing), Ministry of Communications, unless such a requirement is exempted by the WPC Wing. Frequency allocations may be different in other global regions.

Six Button Wireless Mouse vs Three Button Mouse

Image
 When I started using computers long back, mouse had only two buttons, a left and a right button. Then came three button mouse with an extra scroll button. I have read that there was also a single button mouse, but I have not seen one. Now here is a six button mouse, that too a wireless mouse with a USB-A Nano Dongle and 2.4 Ghz wireless connection. In the earlier era, mouse had a rolling ball which would gather dirt and sometimes stop functioning well. Now we have optimal mouse which uses a red light source and an optical sensor instead of the rolling ball. The wireless mouse works on a single 1.5 V, AA battery with a projected battery life of one year!

Debut Ham Radio Technical Discussion Net on 7065 kHz, 1:45 am UTC (7.15 am IST)

Image
Started by calling CQ on 7065 kHz using my automated CQ call which I had described yesterday. VU3RFT joined first followed by VU2EHA. Had a good discussion on Center Fed and End Fed Dipole Antennas. VU2EHA and VU3RFT participated. All of us were using inverted V dipole antennas. VU2EHA had 40 and 20m dipoles on same mast. VU3RFT was using 1:1 current balun. I mentioned that I am using 40/10m center fed dipoles with 1:1 current balun. VU2EHA asked about 15m dipole. I suggested that the 40m dipole will work well on 15m as it is an odd harmonic. He mentioned a problem because his IC-718 does not have an autotuner. We lost propagation at around 7.35 am IST. Wonder whether there was a geomagnetic storm? Number of waterfalls on 40m band decreased very much at that time. Planning to try again tomorrow at the same time. SWLs can monitor at  http://vu3wew.ddns.net:8073/ , the OpenWebRX by VU3WEW, located about 10km from here and likely to pick up my signals very well. Being a WebSDR, it can be

Building a Tape Measure Yagi for LEO Satellite Operations

Image
 The Moxon Yagi which I have been using for my LEO Satellite operations had a Moxon rectangle for VHF and five UHF Yagi elements which were passively coupled to the VHF Moxon driven element. The gain was not that high when I thought of working SO-121 QRP satellite. VU2TEK had good success with his Tape Measure Yagi which motivated me to go for one. But I don't expect the same success as he was operating outdoors, pointing the Tape Measure Yagi in the direction of the satellite pass. I am planning to use only in a mast mounted fashion which will limit its usability for satellite passes to a short period of about 4 minutes. I have chosen the DK7ZB design which I have been looking at for a quite a long time. That design has 5 elements for VHF and 8 elements for UHF with a boom length of about 1.5m. First step was to get a wooden reaper to use as the boom. Earlier it used to be available in all electrical wiring accessories shops. But now with the usage of PVC channels for wiring, I w
