First 10 RGO ONE transceivers available soon

Thanks to all who wrote me with questions, interest, expectations and positive “WOW” feedbacks.
This urged us to move fast forward and start production of the first ten ready-to-use units. We plan to have them finished till next months. Then next lot will be 100 units probably some of them or most of them will be in a kit form with populated SMD boards with small foot print components.

At the show in Dayton we revealed our target price for the kit base version – $450-$550. Hope to keep it as low as promised but final price will be available soon after first units come to alive.
First units will ship from Bulgaria, then for US customers will try to have stock in US.

So far we have two samples that we tested already in real conditions and worked several contest (LZ2RS helped with this task). They were presented locally in Bulgaria and on Dayton HAM vention 2018.

We’ve been working hard for almost three years to see what you saw… A real performer HF 50W CW/SSB transceiver. We are 4 people in the team.. Other teammates are very good in industrial electronics manufacturing and helping very much with electronic PCB design, parts delivery, microcontrollers and other things.

RGO ONE day one at hamvention 2018, Xenia OH

After the successful presentation start of RGO one we made some contacts on 40/20 meters. Here is a short video of a special event station for the hamvention – W8BI

RGO ONE on Dayton Hamvention 2018

RGO ONE homemade transceiver will be presented during this year HAM convention in Xenia, OH (18-20 may 2018). We welcome everybody to visit our booth #8014. Congrats for friends from AMECO who will give us a shelter.

Right after the HAM convention in Dayton pricing, configuration and availability of the radio will be known

CQ WW 2017 with my all new QRP transceiver

CQ WW DX contest 2017 participation.
First QSO’s with my new transceiver Rgo One.

Here are the results:
Band     QSOs     Pts    ZN   Cty  Pt/Q
3.5       235       265     8      44     1.1
7         275       405    16     58    1.5
14       108       188     12     42     1.7
21        55        103      12     22    1.9
Total     673       961     48    166   1.4
Score: 205,654
1 Mult = 3.1 Q’s

Band conditions were pretty good (though I haven’t heard stations on 10m).

Here is P40L on 20m:

Here is 6Y0W on 20m:

IF/AF unit

This unit includes the following:

  • intermediate frequency IF amplification – MC1350
  • optional crystal filter
  • RX product detector – SA612
  • AF preamplifier – LM837
  • RX MUTE and sidetone input circuitry
  • AF final amplifier – SA58631
  • Fast IF 134kHz Automatic Gain Control scheme – SA612,LM837
  • Optional AF filter board

 

MIC amplifier, DSB, CW modulator unit – SSBGEN

In order to form DSB/CW modulation on TX, a SSBGEN board is used.

It consists of the following parts:

  • Microphone preamplifier and TX audio amplifier – TL082
  • Switched input: LINE IN or MIC (MUX 4053)
  • DSB modulator – SA612
  • CW drive level and form circuit – ½ of MCP4631 dual digi pot
  • SSB drive level (mic level) – ½ of MCP4631 dual digi pot

 

BAND PASS FILTERS

Six band pass filters were built to cover 10-80m bands on RX. Schematic utilizes Skywork solutions AS169 PHEMT GaAs SPDT switches, used in modern wirelless equipments. In order to perform individually “fine tune” a variable coil inductors are used. The module fully meets project CLICKLESS concept as there aren’t any mechanical switching components. MCP23008 serial controlled I/O expander is used to engage needed filter. The board has a provision for two optional filters.

Custom made control knobs

Three types control knobs are used in this project:

MAIN dial knob – for VFO frequency tune

capture

ENCODER knobs – various functions

rot-enc-knob

DUAL CONCENTRIC knobs – AF/RF gain control

dual-conc-knob-fit

 

FACE PANEL MOLD PLASTICS OR ALUMINUM MACHINED

To bring more professional and stylish appearance we decided to design custom front panel especially for this project.

argo-one-face-plate-silkscreenface-plate-new-measures-1

Next question was: Injection plastic mold or machined aluminum

First, we made one prototype of machined aluminum in order to test if everything in design is right on the place

Then we start building (ordered) our face panel plastic injection mould. It is known that this was pain process and it took almost 3 months to build it .. after three revisions here it is now ready to “SHOOT” our plastic panels

We made some samples of all three materials available: Glass filled polyamide (black colored), Glass filled polypropylene (grey colored), ABS plastics (white colored)
