how to improve antenna for portable radio?
网页2023年11月2日 · 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).
best portable radio for MW and LW - RadioReference.com Forums
网页Location. S.E. MI. Apr 7, 2022. #3. For MW, my first choice would be the CCrane Radio 2E... IMHO by far the best portable for AM broadcast band DXing. It has a large ferrite antenna and also provision for an external antenna. This is my go to radio for AM BCB DX. If cost is an issue, almost as good and for less money is the CCrane Radio EP.
Is anyone into vintage multiband portable radios?
网页2023年4月15日 · I’d classify a vintage multiband portable as a solid-state radio with an analog tuning dial, a built-in telescopic whip antenna, a carrying handle, and the ability to run off batteries. At a minimum it should be able to receive AM/FM, plus at least one shortwave band. Many also added the VHF police and air bands, and some even added a VHF TV ...
Quansheng Quansheng UV-K5 Radio... downloading software.
网页2023年12月21日 · Feb 1, 2024. #7. In Europe the Quangsheng UV-K8 (8) or UV-K6 is verry popular as you can flash custom firmware to this radio. I use github.com to flash Egzumer (v0.22) or UVMOD direct from the browser to the UV-K5 (8). Works like a charm and it’s a big improvement over the original firmware.
What is the true duty cycle of a portable radio?
网页Oct 31, 2018. #5. alcahuete said: No idea if the radio components themselves can, as the duty cycle does not refer to the radio itself. The duty cycle refers to the battery, and the length of time the battery will last between charges using a 5-5-90 cycle. If a battery is 5-5-90 rated for 8 hours between charges, if you go 10-10-80, for example ...

Best radio for MW DXing? - RadioReference.com Forums
网页2015年2月5日 · The Sangean PR-D5 is an excellent MWDX radio. You don't need an external loop to DX with it. The narrow bandwidth may not be for everybody -- the 4 khz bandwidth makes for terrific selectivity for a portable but muffles some of the highs, which may be an issue for some people. Sells for around $70.

网页2020年12月14日 · You might want to look at the Jay Allen AM Portable Mega-Shootout. He rates the EP-Pro in the top category with the likes of the RF-2200 and CCRadio2E/3. Considering the CCR2E is $170 and you'd be very lucky to find a used RF-2200 in good condition for under $200, the EP-Pro at $90 looks to be a bargain.

I'm willing to sacrifice a little coverage or performance for a shorter ...
