I often go searching for technical information on consumer electronics. I want to get a look at the user manual for a new radio before I buy it, or I want a searchable electronic copy. Persistent digging has led me to a website, Device.Report, with a phenomenal database of information, including FCC type certification test results, product teardown photos and user manuals.
There are a multiple ways of searching the site. I use a Google search on the model number like this:
site:device.report “HRD-701”
It returns what I want most of the time.
There is a search built in to the home page, https://device.report/, but it required the brand. There there are also index pages for many brands, including these:
- https://device.report/choyong
- https://device.report/eton
- https://device.report/grundig
- https://device.report/hanrongda
- https://device.report/kaito
- https://device.report/lijiani

Dear Kevin,
Am just about set up to do a signal report test on the Eton Elite Exec. So far I’ve determined the LINE OUT (stereo config) jack supplies around -22dBm on either channel with the radio tuned to the noise between stations.
Have also determined some Continuity pathways, to wit:
The external stereo headphone jack (3.5mm with Tip, Sleeve and Ring) has the connection from the Ring conductor to the radio internal ground plane which also serves as RF Ground on the External Antenna 3.5mm Stereo Jack.
Have determined the connection of the five different solder lands connecting the External Antenna 3.5mm Stereo Jack, thereby refuting another observer’s declaration of the External Antenna Jack needing a Two-Pole (Tip/Ring 3.5mm MONO)plug.
Have determined the D.C. impedances surrounding the three poles of the External Antenna Jack, in that Tip1 has infinite resistance to the Sleeve, or “Tip 2,” forward and reverse meter probe polarities.
Have determined Tip1 has a 50 ohm impedance to RF Ground, front to back when the front end selector switch is on DX, but changes to 268kOhms, Frontways and Backways with the switch in LOCAL.
Have determined by rotating the TUNE control on the side of the radio the VFO will continuously tune from 150KHz through 30.0 MHz without need to select a band from the front panel buttons.
Have determined the FM band will tune from 64.0MHz through 108.0 MHz, inclusive.
The next set of tests will determine the radio’s response in dBm through the LINE LEVEL 3.5mm Jack, through an adaptor to dual BNC males, into an o’scope front end that portrays Ch1 and Ch2 in different colors to allow superimposing the wave forms.
I need to determine the effect of an antenna connection to the External Antenna jack via the Tip1 and Sleeve conductors, throughout the radio bandspread.
I need to determine the effect of operating the DX/LOCAL slide switch on that connection, throughout the radio bandspread.
I need to determine the effect of a close-coupled connection to a superior outside dipole antenna to the internal ferrite rod antenna throughout the radio bandspread.
None of these parameters and connections are addressed in publicized form by the manufacturer. There are plenty of people lauding the radio, and plenty detracting, but there are few objective analyses to support contention.
Lastly, Eton Incorporated has not seen fit to answer any of my politely addressed questions, nor have they seen fit to furnish me with a wiring diagram or circuit schematic, which in themselves would go a long way to determine the viability of this product.
Great website. The FCC ID database is a great resource as well.
