Re: Cybernet PTBM121D4X problems
Did a fairly comprehensive test on all 3 bands, i left sig gen on whilst i swapped
radios to try and make sure it stayed where it was, the only adjustments i made were between bands and the fine control when i tested on that perticular channel.
the colt is pretty much bang on frequency wise. i sorted that at the weekend,
it was pretty close to start with.
the results are as follows with 3 positions on fine control as there is sometimes
a small peak at the 2pm position plus full anti clockwise and full clockwise.
27.525 777 anti/c s8.5, 2pm + of +30 c/wise s9 to +30
colt 320 anti/c s7.5 both 2pm and c/wise read s9 to +30
27.205 777 anti/c s8.5 2pm s9 to +30 c/wise + of +30
colt 320 anti/c s8 2pm and c/wise s9 to +30
26.855 777 anti/c s8.5 2pm line before + of +30 c/wise s9 to +30
colt 320 anti/c s7.5 2pm line before + of +30 c wise s9 to +30
did find a funny thing with 777 when i switched it on and it was still on ch50
i could hear the sig gen on it and an s7 signal and the sig gen was on 27.205
ive heard the 777's are a bit iffy image rejection wise, i soon lost it when i switched band down 40 channels to ch10 mid then went up to 20.
overall i looks like not a lot in it
the colt does tx on all bands but very low on both am and fm less than quarter of a watt flat out !
