Retevis is giving away THREE radios for their 16th Anniversary! Click Here to enter!
One of my friends from another forum knows Anthony personally and relates that he goes out of his way to make sure he's not causing problems with others - either fellow radio operators or the general public.
That type of attitude pays off.
One wonders how long the shenanigans raged before the FCC was galvanized to action. Or what the final straw was.
In cases around this area, idiots jam and act the fool for years without a hint of attention.
Then there's the crowd which turns Ch38 unusable as long as skip's up.
And the...
If an RF signal generator is available I'd inject a test signal right before the 1st mixer then work backwards towards the antenna connector.
If that inductor is bad, wouldn't be the first time for this symptom. L41 in the TS-530/830 series Kenwood hybrids and a couple of them used in the Tempo...
I too had an early 2950. A "tradio", passed around from owner to owner.
Once I got the previous owners out of the thing it was a good rig. A buddy of mine had to have it more than me so he offered some things in trade. One of which was a Nato.
Galaxy used to advertise in the radio mags way...
It was an adventure on Usenet and several other radio related sites I'm familiar with.
A couple others jumped on that bandwagon as well. Textbook example of the term "overcompensation".
As a user of all radio services/allocations to which I have legal access, I'll say this:
If I can't hear you splatter into or don't find you operating illegally on an amateur band, I simply don't care.
If you're operating on another (non amateur) service that you aren't licensed for, that's...
Bob,
A 10x probe should attenuate whatever you apply to it by 10 times. In other words, if you set the scope's vertical deflection to 1V/div with that probe attached it will take 10v to deflect an entire division.
What is the scope's maximum vertical deflection setting? I'm thinking...
Slightly off-topic but still noise toy related:
Anyone remember the TI SN76477 sound effects chip? Used in a LOT of video games of the 70s and early 80s. I still have one in my junk box.
One of the electronics mags of the period had a noise toy construction article. I played around with the...
How familiar are you with troubleshooting - specifically, tube PA circuits?
For starters, have a look at all voltages involved with the final. Specifically, screen grid and plate. Be careful. Are any of these dipping as you transmit? And when looked at via scope, are they clean, stable and free...
The best way I can describe DSP artifacts is that it sounds like you're talking under water. Very low levels of DSP filtering (just enough to remove the most bothersome background noise) aren't that objectionable. Get more aggressive with the filtering and it's definitely noticeable.
What I do is apply some with the solder pencil of my rework station, hit the part with hot air (lower temp than required to melt 60/40 or similar solder) or use a Thermo-Tweez handpiece with the appropriate tips. After the part is removed, flux and clean pads with a Sodr-Xtractor, melt some...
I try to keep those frequencies in the memories of any receiver that's capable of storing and scanning them. Have heard traffic a few times over the years but none in English.
Another favorite thing was monitoring 27540 for packet radio transmissions. I had many megabytes of those exchanges...
