Subject: [UltralightDX] Portable Ultralight Radio DXing Case - July 2021

Recently I have been on the lookout for a suitable carry case for my ultralight radios. I have found that carrying my 3" FSL plus all my radios was overkill, mainly when I find I am mostly DXing "barefoot". 

My local Bunnings has a range of cases and I found that this one was the best size for my needs, it cost $16. The foam that comes with it is pretty poor so I replaced this with a much better piece of foam, this cost $33. The total is under $50. I also added the velcro strap to help keep the case closed securely.

I have setup the foam today with cutouts for my three main ultralight radios plus spare batteries and charger, ear phones and notebook / log sheets.

I am very happy with how this has turned out and think it will serve me well.

I have a Tivdio V-115 - the AM and FM performance is so-so, with odd digital noises popping up here and there. On the other hand, the recording function does a very good job, better than comparable products from Tecsun, though not as good as a separate, dedicated recorder such as one of the Tascam models. The speaker sound is surprisingly good for a radio of its size. The user interface is quirky and you can't press the buttons too fast, otherwise the radio will just ignore you.

First Impressions:
I recently ordered the Retekess V-115 FMAMSW Radio off eBay, for under $30 it seemed like good value and the built-in recorder to an SD card seemed like a feature I could make use of.
Physical – The radio is fairly small / light and seems to be built as well as you would expect for a radio at this price point.
Usage – from my testing so far, it seems to work as I would expect and pulls in signals “barefoot” as well as my Teac PR130. I feel so far that my Digitech AR-1733 still has the edge in RF performance.
Issues – So far, I have found a few issues. The tuning modes are that you either manually enter a frequency via the keypad or you use the auto tune modes, you can’t scroll from frequency to frequency, say from 531kHz to 540kHz, you need to either enter each frequency or use the auto tune modes, these only work on the strongest signals so for serious DXing, this is a huge disadvantage. The display backlight is VERY bright which means it is not easy to use in bed, it lights up the whole room, this reduces the “wife approval factor” as it looks like aliens are in the room. I have also noticed that the buttons are hard to press and have a noise with them, this also makes bedtime use less than ideal. The recorder works well but names the files RAD001, RAD002, this means I need to keep a record of what frequency each recording relates to.

Overall, I am on the fence with this so far, while it has some good features, the tuning mode is going to be harder to use and the file name for the recordings is a pain.

Re: ABC DRM Transmissions

Richard Allen
 

I agree.  They only reason I can hear DRM is because it was included in the software I use to listen to my WiNRADiO SDR.  

You can have a listen to the difference between DRM and AM by going to:  https://www.drm.org/what-can-i-hear/

It seems their is a push to put DRM receivers in automobiles in some countries.  Here in the USA a lot of modern car radios can receive digital signals (not DRM) which are piggy-backed on the existing channels in the FM (88-108 MHz) band.  The receiver in my Toyota Tacoma can receive them where available.  They have tried something similar on the AM (540-1700 kHz) band here but it has fizzled.

Five Days In:
Sound quality from the internal speaker and ear phones is good.
- Tuning method while not easy to start with is making more sense as I use it.
- Excellent battery life, I have only just needed to recharge it after 4-5 days of heavy usage.
- I have grown to like the backlight. While it is bright, I have managed to get use to it.
- DX performance so far is solid without being amazing. I am yet to test it with my 3" FSL.

Spot on Art and pretty much what I have also found.

One question, when you use earphones, does your internal speaker disconnect? I have noticed with mine that even with earphones connected, the sound still comes out of the speaker.

I bought mine for $18 via Walmart. It's a good $18 radio and is a nice utility backup to my more DXing portables.

It is also slightly bigger to be considered as a 'Small portable' which is here in Europe 500cm3 (30,5 in3) as maximum size. The Sony is 506.013 cm3.

We are cleaning out our house getting ready to move.

I found an old Sony ICF-SW10 12 band radio.  The tuning knob was missing but a small plastic
plug just happens to fit into the location.

It's dimensions (w/h/d) are:  Approx: 162 x 93.8 x 33.3 mm                                   
                                              6 1/2 x 3 3/4 x 1 5/16 inches
