I forwarded the information to the GQRP club forum which started a wave of panic buying, mass modifications and loads of fun! All the radios in the special offer are now long since sold out, but thanks to an email from Alan Edwards we now have a new source.
The "Gelert" range is stocked by lots of camping retailers. Alan got his from Great Outdoors who have a store in the Chester area. Click images for larger photos!
There are several canned IF transformers, and a plastic-cased kHz ceramic filter. Tuning is via a polyvaricon variable capacitor, i. The tuning knob is not geared, so tuning CW could be tricky unless the band could be narrowed somewhat. Features and Specifications Basic information about the capabilities of this little radio, and band coverage measurements from two radios vs the instruction sheet. Read more How to open the radio without breaking it! On the back there is a flap of plastic which flips out and allows the radio to stand up on a table.
When the flap is flipped, there is a small screw behind it which must be removed. Next, notice a small switch on the righthand side of the radio, next to the tuning thumbwheel. Frequency Counter board Lots of connection data for the frequency counter board, how to use it, how to dismantle it, etc. He used a zener and a miniature 9mm pot to add a fine tuning control to the radio. Superdrg radio goes DX! Read more.. More modification ideas Superdrg radio on Topband! Richard Constantine G3UGF discovered that by fiddling with the band selector switch between first and second positions MW and SW1 bands , at a certain setting it is possible to tune Topband from kHz to 1.
This appears to be some shorting in the switch doing wierd things with the oscillator circuit configuration. Rick Peterson 2E0JSI also reports that by sliding the switch to the far right it appears possible to tune He says: "80mtr enthusiasts may be interested to know that padding the blue tuning can with 56pf and re-tuning, the radio works well on that band.
The downside however is that you loose 30mtrs and top band. When using an SA to mix a The cores have limited adjustment range and stiff adjustment, but are stronger than most ferrites.
He broke a nylon adjusting tool and resorted to a normal screw driver. Pulling pin 1 of the frequency counter ribbon low with a 3k resistor selects the high resolution 1kHz range on the counter. Trevor removed the transistor above the ribbon, inboard of the volume control and wired a 2k7 resistor from ribbon pin1 to the low pin on the tone switch under the tuning cap.
He has not yet found any sign of front end filtering on SW, so the image responce might be wide open. CDCB datasheet - this one is in Chinese?
Equivalent to the UTC UTC datasheet - equivalent to the SC This is the IC that was originally thought to be in the radio. Similar to UTC Design GO travel clock radio. There is a pin to control the resolution! It can be set to display 0. This is more convenient for amateur band operation. Last Updated on Monday, 22 December
