Jel drug YT1NIV postavio negde šemu ovoga ili gospodin YT1NIV to samo prodaje?

Retevis / Tytera / Odg: Retevis - RT3, poboljsanje modulacije
Jun 28, 2017, 11:23:02 PRE PODNE
Probao bih i sam, samo nisam siguran da bih mogao obicnom lemilicom da zamenim SMD komponente. A i trebalo bi poruciti nemam nista SMD :

Retevis / Tytera / Retevis - RT3, poboljsanje modulacije
Jun 28, 2017, 10:42:34 PRE PODNE
Zdravo,
naleteo sam na clanak u kojem je opisano na koji nacin se moze izmeniti RT3 da bi se dobila malo bolja modulacija.
Zanima me da li je neko ovo radio i kakvi su rezultati? Citiracu ovde tekst iz clanka jer je na mods.dk a tamo je limit na jedan post na dan.
"After having a look into the schematic I gladly recognized that the MD-380 has a mic compressor, or let’s better say a 2-stages mic amp limiter. This I only know from the WOUXUN KG-UVxD yet and they sound very good and are never overmodulated or distorted. With slight mods they run even better with a powerful FM modulation."
"By increasing the bias resistor of the electret capsule audio dynamics come alive.
On the other side the mic compressor timing is a little too fast which causes a little “rough sounding†audio on each limited peak. So I slowed down the 2-stage mic limiter a little bit which ends up in a good compression and the rough audio effect has gone. The mic compressor is still very fast and does not have the typical pumping effect or slow release on the decay period."

Retevis / Tytera / Retevis RT3 - previsoka voltaza punjaca
Jun 20, 2017, 08:19:05 POSLE PODNE
Zdravo,
pretrazivanjem interneta u potrazi za informacijama svim mogucim i nemogucim a vezano za Retevis RT3
naislo se na odredjeni blog u kojem kolega nam objasnjava zasto je voltaza od V8.53 previse za Li-Ion bateriju
koja se nalazi u ovom uredjaju. Naravno, tu je i kako sniziti voltazu na odgovarajucu.
Pa reko cisto da podelim ako neko nije naisao jos na ovo:

Ima tu jos kojesta pa eto, 73!

Zdravo,
ima li neko RDT codeplug fajl da mi pošalje da probam neke skriptove dok ne napravim kabl da svučem codeplug sa uredjaja?
TIA, 73, Filip YT7FMS
