The OM0ODB converter is dismantled after the conversion from a pure D-Star to a dual D-Star + DMR. HW bude MMDVM + Arduino TWO + Raspberry Pi B+. radio, duplexer, the source and antenna remain flooded
You get nan after rebuilding with this device?
Unless, which affordable devices support dstar?
Thanks
The story of VEASU… You can't rest with Chinese stuff? Not enough experience with a Chinese mobile phone?
OM0ODB does not support FM modulation, so you need something else
Compatibility: https://en.wikipedia.org/wiki/D-STAR paragraph “Transceivers—D-STAR and Analog FM Capable”
But for 60 € D * you can't even use it….
Dik.
That cell phone was a hit, I agree.
But also UV3R + for 25 € is a fantastic station, I will not allow it!
With 2-3W I will open Inovec and Sitno and make a reasonable QSO. UVB6 is also usable, although the receiver is weak there…..
Really that biquad would also like a few coax turns? After all, it is symmetrical and feeds asymmetrically. This has an impedance at the connection point?UV3R is also a very hardy radio, if he sees on Flarion BTS then within 300m from BTS the sensitivity is evil. I have this BTS (also UV3R to break for the bike) led the house, so my know… Yeasu VX2 no problem…
Anything built on the RDA1846 if it has something very strong in the ENTIRE band accepted, so it has tens of MHz parameters elsewhere on the received frequency… Tak staci Flarion, Tetra, Matra… The chip has a dynamics according to 85dB papers, but the UV3R input filters are designed so that they run a very wide band for UHF, and even before the chip there is a preamp over 15dB., which still significantly worsens the parameters of the beetle.
But you will only find out that it is a radio in a given place on a given noise frequency if you have led yourself to something even more normal for comparison 😉
For running in places with a strong signal from the local driver, it is radio ok, especially for that price, but…
I tried to improve the radio, helped, the radio is more usable, but miracles do not happen.

I have uv3r +, so maybe we don't have the same radio.
There is no bipolar at the input, what someone here once criticized, but any high tech dual base mosfety. When we go to sota together in the summer, we compare.
From the radio, co stands 5nasobok, I would also expect some better parameters.
A ten balun z koaxu k biquadu na 70cm ma, ci nema byt?We've had enough OT but I'll answer you later, with a balun, your biquad antenna will be less “skulit”. http://www.g0ksc.co.uk/creatingabalun.html
Your problem in your vertical practical design as I saw it from the car yesterday is, that you pull the drain straight down, which affects the impedance and the radiator. The lead should be L / 4 perpendicular to the biquad and then down.
Biquad without reflector has an impedance of about 100ohm, with the reflector it can be reached at 50ohm, distance reflector – biquad changes impedance and diagram. Due to your use, when no lobe is heading for your apartment, I would put the spotlight there, gain over 2dB gain, suppression of house interference and reflections. http://www.porady_ukf.republika.pl/strona/index1.html . With three reflector elements from 8.5dBd…
Next, please stick to the topics or create another fiber, this is not about antennas or Chinese FM series 😉 . Well thank you
Spat k teme, HW OM0ODB ready, MMDVM HW6.0 prisposobeny na V6.1, I'm struggling with a broken programming port, problem probably in 16U2 on arduino due.
The converter is already running in a trial operation with a reduced power of 5W and 35m of cable from me from the house – Dubravka. If there are no further inconveniences (and it was their par) so by the end of the week it could be on stable QTH.
Current clogged systems:
DMR, Translator ID 231111 – connected to Brandmester 2302 (with support from OK) https://brandmeister.network/D-Star, connected to DCS019S, after linking to another reflector will return after 10 minutes without operation sleep.
C4FM (Fusion), so far without network connectivity and untested, I don't have a C4FM radio, if someone has me and wants to try, please contact me.
The systems switch automatically, the active type of operation is allocated 10 seconds after the end of the session.
The converter transmits the CW ID in FM, so far everyone 5 minutes.
This permanent qth will be in Kamzik?

Well fajn.ja I have Yaesu ftm 100. I will try the C4FM mod. We are even quite far from each other Tono, however? 😀
You just forgot to write the essential thing,where to tune it.
Ake will be stable qth
? 🙄Operating parameters are available on the site:

73, OM5NAAha, so somewhere between the Old and New Towns, as well as the digital bridge between the old and the new world, the best of each. 😳

Chamois? Technically possible, one UHF part of the antenna free but… There is no connectivity, another antenna for internet over 13cm or 5cm = charges, use of internal network = charges, if you contribute tens of € a month, so it can be. LTE has a big ping there (he sees a lot of BTS) and HW and the flat rate is also not free. The frequency would also have to change, collision with OE3XNR and change of permit.
So QTH will be the same as YET, it is a reconstruction, not about moving, RPT operated as a pure D-STAR for a few months until September 😉
