The radio can pick up the antenna's re-radiated signal via induction. Sometimes placing the whip near the feedline or the end of the wire -- without touching it to the wire -- will improve reception. I did this with a Radio Shack portable in the 1990s and got decent results (the radio was the DX-370, a portable with no EXT antenna jack).
A discussion thread about portable radios for medium wave (MW) and long wave (LW) bands, with suggestions, reviews and tips from users. No direct answer for fm sw mw radio, but some radios cover these bands as well.
A user shares their experience of downloading the programming software for Quansheng UV-K5 radio from the manufacturer's website and warns of possible malware. Other users comment on the risks of buying from China and using virtual machines.
No. Portable radio features vary by make and model, as do the specifications. Transmitter duty cycle will vary widely. It's frequently not even specified in portable radios, as typical commercial or public safety use doesn't come anywhere near 100%.
An excellent overall value for a radio that usually sells for just less than $20. The Sony ICF-38 is a portable with speaker and good sound, and also DX's well. It has a hot IF chip in it, and I think it has an extra RF amp but am not sure. Acts like it. Sells for around $25. The Sangean PR-D5 is an excellent MWDX radio.
Create a standard where a basic radio is built into the SCBA to allow communications. This nonsense where every fire fighter needs to be carrying a $7000+ multiband portable radio with AES256, trunking and all the other crap is just down right silly. NFPA should have focused on a standard that stuck to one band and built it into the SCBA.
I'm restoring my '72 Pontiac Ambulance and was given a box of GE goodies, including a MASTR control head already jumpered to power on as if it had a radio behind it: green standby, red PTT. I also was given the old PE, that I was going to use as my ham radio, while adding to the look. I am already using my dad's '82 IC-27A as a mobile in it.
Sangean has a newer radio the ATS-909X2. Earlier versions of that radio were known for being a little "deaf" but this one seems to have overcome most of that problem. C.Crane has decent radios as well. The Skywave SSB is a very nice small radio. The swling post has radio reviews.
Portable / Mobile radio lifecycle expectations & costs Whoops. Edit. Missed the fire service part. I believe NFPA has draft guidelines based on NIST tests and real world scenarios since their standards on radios are due soon.
For the money, being able to rotate a ferrite rod on the radio, the built in DSP and the tuning ability to grab 72 stations on MW with the PL-360 sitting inside at 3AM is more than enough for me. I have not tried the same test for daylight hours during the summer, I am sure it would be a lot less and horrible listening except for strong stations.
