I am talking to a local on 38 LSB. I am cutting out after about 2-3 seconds of
talking. He says I am fine for about 2-3 seconds, and then just go dead. Not
happening on AM. I switched power mics, with the same result. Also happend on
USB. Then I went and put the radio in the car, and the problem went away. The
local said it's my power supply not having enough juice. But it's 12 amp
constant, 14 amp surge. It's a PyramidPS-14KX. Again, I am running barefoot with
a HR-2510. Is it the power supply? Should I add more caps for filtering?


I need a little more information. Do the radio lights actually dim
when this happens?

No.

Hmmm.... I suspect that this is not a simple insufficient current
"power supply" issue. The power supply may be related, but there's
something else in the mix that we don't know about yet.


I does seem to sound like a power supply issue, but
you should be able to talk farther from the mike (Which allows the
radio to not peak as highly) and if it's a simple supply problem, at
some point the radio will work ok if it isn't putting out full power.

The 2510 should not draw more than about 5 or 6 amps, depending on
whether the radio is totally stock, or whether the ALC has been
cranked open (Which will allow a 45 to 50 watts peak SSB output).

I have not modded this radio. I am waiting on a dummy load. I do have a
question. How high can I DK it and how how can I turn up the ALC, without
overdriving the final?

Is this the older version of the 2510 with the MRF-477 final in it?

If so, the radio is capable of between 45 and 50 watts of peak SSB
power (with the ALC cranked open). For best power with some protection
from distortion, you can safely run it up to between 35 and 40 watts.
It's also capable of about the same peak power on AM, which means that
you should not set the carrier power above 12 watts, if you want to
maintain enough headroom for 100% modulation.

Be careful though, the MRF 477 transistor is no longer manufactured,
and there is no direct replacement for it. So if you blow it, your
choices become limited. You might be able to locate someone who may
still have old stock of the '477 (at a premium price), or you can
retrofit another device, which can be done, but usually at a loss of
peak power out.

Dave I am hearing CBers on AM in the 10 meter cw band right now.
Thanks for helping another unlicensed outlaw get his peaked up tweaked up
illegal rig on the air to join them. Putz.


You're welcome.

There you go Dave, you have "enabled" an outlaw Cber
and he even used the 56 in a 55 mph zone excuse. Proud?

Depends on the state. Most states give you 10% leeway for differences in
speedometer calibration. Oregon doesn't have speed limits in most places,
opting for a less strictly enforced posted speed (difference is the posted
speed signs say SPEED, whereas hard limits say SPEED LIMIT). In either
case, if conditions are bad, you can get a speeding ticket for going slower
than the posted speed (ie, doing 50 in a 60 zone on ice).

No they don't. The speed limits signs or laws do not say 55 or 65, +/- 10%.

That is nothing more than the descretion of the cop that tickets you.

In Pa. they are required to give 5 MPH to take care of "Speedometer"
and speed measuring inaccuracies. In addition, just to avoid court
challenges to the precise accuracy of the speed measuring equipment
(Usually VASCAR on non-state patrolled roads, and RADAR on state
police patrolled roads), most of the cops I know tell me that they
unofficially give people 9 MPH over the posted limit before they start
pulling people over. Of course there might be a new hard-assed rookie
who might not be so "kind".......

That depends on the state. Some states (I believe Maryland is one)
have what they refer to as "Zero tolerance" 65 MPH. They can bust you
for 66, or so I've been told. I don't know how many cases have been
fought over speedometer or other potential speed inaccuracies and how
well the "zero tolerance" aspect has held up.

Most car speedometers are not so accurate that a 1 MPH difference is
all that hard to believe. Just putting one size larger tires on your
car can make that difference.

People have fought a speeding ticket on this basis and have won.
That's part of the reason why Pa. gives some leeway. Most cops don't
want to have to appear in traffic court when the chances are good the
case could get thrown out. However, it's a lot harder to make a case
for speedometer inaccuracies when you're 10 MPH or more over.

Oh, because someone else breaks a "law" you are entiltled to break any
"Law" you see fit. Grow up Vinnie, quit trying to rationalize your
behavior.
