Today we made continuity and DC test of the front panel assembly consisting of:
CPU board
LCD&switch board

All tests passed OK and tomorrow face panel’s CPU will be flashed for the first time

We recently received first ten sets of printed circuit boards for RGO ONE HF transceiver.
So till today we managed to populate some of the boards. Rgo one consist of 20 pcb’s … so a lot of work lies ahead.
LCD&switchboard – finished:

LCD&switch board component side:

IF/AF (intermediate 9MHz frequency – audio frequency) board

Search and pounce in LZ DX contest with RGO ONE. Testing new features – DTR/RTS keying from N1MM contest logger; Testing temperature management with new FAN cradle.

Here is in summary what happened after Dayton HAM vention.
We noticed some issues in spectral purity in RGO ONE transmit part. So we had to move it back to design stage and for almost three months we dealt with these problems. We had to redesign RF MIXER, power amplifier and some other boards in order to improve spectral purity (now it is far better than -43dbC requirement) and linearity.
TX mixer SA612 matched to 50ohm with transformers. Balance potentiometer was implemented.
Amplifier between TX mixer and band pass filters was removed. Additional GALI-74 stage was involved after BPFs.
TX/RX antenna switch in LPF board was changed in order to block positive feedback and improve final amplifier stability.
Power amplifier board P55W includes the following changes: Predriver and drivers were changed to ST microelectronics PD85004 (they are far better than RD06/RD15); Output transformer has been redesigned with Fair rite 43 material core and ratio 1:9.

On receive path – gain distribution was properly adjusted so now the receiver is more quieter.

We recently tested the equipment in LZDX and CQ WW DX contests and it performed great. (LZ2RS Rumi worked with RGO ONE transceiver in category SO 15m QRP)

LZ2RS is getting ready for this year CQ WW DX contest CW part SO 15m QRP

So now we are proceeding with first lot of 10 pieces which will be fully assembled and aligned. I hope they will be ready till mid january.

Upon received feedback of ready to use transceivers we plan kit production for next year.

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.

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 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

Rgo ONE HF transceiver has built in CW iambic memory keyer.
1. Speed 5 – 45 WPM
2. Keying mode – Curtis A; CMOS B (Accu keyer;CMOS keyer but with 30% more tolerance)
3. 4 memory locations with 128 symbols each
4. Beacon mode
5. Normal/reverse paddle
6. Eligible dot/pause ratio (0,9 – 1,25)

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:
