Between Nako and Tabo on bikes 2010 From Nako the road climbs another 300m to 3800m to get around the stream that erodes away the road a little bit more each year. Before long the road will have to climb to 4000m if they don't bridge it somehow

From Khab at the confluence of the Spiti and Sutledge rivers to Nako 2010. Now the new Bridge is in use and the hotel being constructed in Nako is the place to stay. It was really good in 2014.

Hello! For me, when the RF gain is 10 hours, the sound disappears completely in USB mode.
And most of the weak signals also disapear. There is a sweet spot but more than 10 oclock. Around 2pm works for me.
@@91dd018 Thanks for the quick response! Then it's not a unique case. They thought I bought the wrong one. Very good radio. 73!
Anywhere someone can point to what all the values in the service menu do? I've seen lists and have a excel sheet listing them, but some are a bit ambiguous. I think from what I've heard out of mine the gain of one of the IF stages is just too hot. On a 250ft balance line fed dipole I pick up a lot and sometimes can hear some stuff that's out of band or whatever that shouldn't be there, basically images or intermod in the radio if it's at default with the RFG cranked. The work around def makes it more pleasant to listen to.
turning down your RF gain is not a fix!
Its a work around
@@91dd018 better to go into the menu to RXNR and select level 3 or higher
@@WPGinterceptor460Interceptor Some radios with lower serial numbers do not have a problem but for those with the issue it is obvious and the noise can be controlled somewhat by setting the NR to 3, but your S meter will still show 5 to 7 with no signal, just the noise. The mod listed here will knock the noise right back and clean up the signal.
@@91dd018 and weaken an incoming signal
@@WPGinterceptor460Interceptor If you have not got a noise problem with your radio and have not done the mod then you can't really add value to the conversation because you don't know what you are talking about. We are talking signal to noise and clarity of the received signal. Of course reducing the RF gain will reduce the strength of an incoming signal but if that incoming signal is masked by noise and reducing the RF gain allows you to copy the incoming signal without it being masked by noise, then use the RF GAIN. Why do you think they make RF GAIN adjustable and give you a knob to adjust it with?
Not working for me. Got the same radio ??.
You will need to be a bit more specific? What did you do?
Did you have the noise problem to start with?
@@91dd018 I don't know if that's noise or it's very sensitive receiver in those radios. with RFG set to max I have white noise at S5 and if I move RFG like you did it that hissing noise won't drop so drastically like in your radio. Did you change anything in the engineering menu. For me to drop noise to the same level as you did I would have to move RFG to 12 o'clock.
@@myszaca Yes. I changed the setting of item 52 (RFG) in the service menu from 86 to 105. That is why I uploaded the video.
@@91dd018 Ok. That makes sense. I wasn't sure why your radio reacted so quickly to drop the noise. Thank you for the tip. 73's.
David Donaldson, Where could I buy a Maxlog M-8900
waiting for maxlog to release them
Donald, where would I buy a Maxlog 8900?
David. I bought an equal radio. I do not know the functions of the menu ... F9 - U9 - L9 - BU and CT. Can you tell me ? Thank you.
OK David. Thank you so much.
the Hi-Cut works well
It surely does!!! ;)!!!
Yes it can work as small step vfo clickety click
That Dang clicking.... can it work as a small step vfo?
Wow, thats a impressive DSP.. Going to have to look into one now :) Wish i could find that 5555N for sale here in the US... 73
Amazon $209.99 to your door in two days with Prime!!! LOVE IT!!!
@@TheTurbo930 noisy receiver
I can you tell me how to work the echo delay I can put the echo on but it is repeating to much on mi maxlog m8900
I have both the Anytone AT-6666 and the Maxlog M-8900, many things alike and a few differences. One thing I appreciate about the Q6 is that the mode stays as set on each channel but not with the 8900. The PBT of the 8900 is not really a true Pass Band Tuning and the current version, mine and yours, tracks both RX and TX. I think it is more of an audio bandwidth. Offset can be had on CW with the Maxlog but you have to change the clarifier to offset, at least it stays in a channel 'memory'. Down side of the Quad 6 is that there is no CW mode! Where I live in the States, the 'Superbowl' can be heard daily on 27.025 and both the Anytone and the Maxlog have low channel 'bleedover'! I'm still learning both but these are a whole new class of rigs! Good showing Dave!! mechanic
Thanks for the video Dave. Could you please do a video showing the size difference between all three of those radios? Cheers
I have gone one better! Check this out. dd182003.wordpress.com
David Donaldson Thanks Dave! Great stuff. I just saw your latest post arrive in my inbox (I am subscribed to your blog)... This might be my next purchase, 5khz steps, small and 12m - 10m. Will be a good friend for my awesome Optima Mk3 ;)
MostlyPostie Just want to streamline some of the programming first. Still a good set regardless. Much easier to use than the Anyclones but the AT5555N does look very promising. Piss off the Channel selector and reposition the clarifier to in place of it, use 2 of the bands as VFO's with a split feature, bigger heatsink with fan, tighter filter on RX and we would have a radio!!!! But it is pretty good as it is too...
