Antenna recommendation for nursing home setting
|
I've been prepping my FRG-7 to lend to a gentleman who lives in a 12 x 13 ft room in a nursing facility..
I'm looking for suggestions of what sort of antenna to set up for him. Do I need to connect to all 3 ports or just one? I modified the radio today and installed an IEC socket with integral EMI filter mostly to improve the ground situation and simplify cord handling. Thanks, Reg |

Hi, could you please document or show some pictures of how you did the emi socket I also have being thinking of doing the same as i have a spare emi socket sitting here unused at the moment How did you cut the metal chassis etc?

With mine I was very impressed that it was quieter than my long wire, as being completely off grid rural, I? suffer horrendous interference from the PV controllers. I bought this just? to try, and now is? in constant daytime use. There are a few dips and bumps in its frequency range, but nothing of consequence. Circuit wise, it uses a balanced video amplifier IC , so any common mode noise, ie, local noise is cancelled to a large degree.. I recommend opening the unit and turning the gain down to improve the signal to noise ratio. There is no need for the 20 or so dB gain it is capable of.??

I made a cardboard template that just fit the socket. I moved it around until I found a good location surrounding the power outlet and marked it off with Magic Marker. I then used a nibbler to cut the bulk of the metal away followed by some clean up with a file. If you have any interest in the radio as a collector's item I recommend mounting an EMI filter under the power transformer. I was going to do that and had even mounted the filter, but then I realized I could find the IEC socket. Finding a cable clamp to fit would be a long exercise in "hunt the wumpus". And I like IEC sockets whereas I despise permanent cords. The nibblers are shown on top. I actually used one of the yellow handle ones with the spring and clamp removed for some of the detail work because I didn't have the other at the time.

Thanks for the suggestions. I'll have an SDR H field probes, spectrum analyzer etc. available. It will take Bill a while to learn to operate the FRG-7 so I'm going go with ~85' of wire stapled to the ceiling with very lightweight staples to start with and then I'll hang out with him with my Icom 705 connected to the same antenna through a splitter. The waterfall on the 705 will be very helpful in helping teach him to operate the FRG-7. Though he was a USAF radio operator. So the PLL and preselector may be perfectly natural to him.

Re the EMI filter did you find this to be a benefit and if so what noise did it help with?

No idea at all. I stapled 100 ft of #26 stranded wire to Bill's ceiling today in a rectangular pattern and ran out of wire just before i ran out of ceiling. I'll go check how it's doing tomorrow. It was really a "I have an IEC EMI socket" and it provided ground and power line common mode EMI suppression. It's very much an "actual miles may vary" world.

just a thought, since there is so LITTLE SW activity today and HF hasn't been the best since march may you could look at other options. Maybe a digital hotspot and a small HT Allstar, Dstar, Echolink, IRLP, DMR, Wires-x, Fusion, P25, NXDN...... on and on and
on... just a thought

The demise of SW broadcasting has been very sad. Bill was a UASF radio operator before getting a PhD and becoming a professor of entomology. He's now in the memory care unit where my brother in-law is staying. Poor guy is surrounded by zombies who don't know who or where they are. He has issues, but nothing like the others. I had an FRG-7 I had aligned sitting on the shelf and thought he might have fun fooling with it. Cost about $3 for the wire.
