Just checked the calendar and the Puyallup Mike & Key flea market is on March 6.

Anyone from Intercept want to meet up with other Intercept people lets make a meet up place and time there.

Say the Icom booth at 11am? Or any other ideas. Idea for a talk in freq for Intercept?

Hope to see you there :D

I'll be there. On P25 on 147.54 :P

I have a booth, so it will be hard for me to meet up at the Icom booth. Drop by and see me, I'll have a bunch of P25 gear F/S. I'm upstairs normally.


Jim

I will be sending some people to your table actually.

For those of us who don't have P25 or Dstar what is a good meetup frequency?

Let us know what table you have Jim. Would like to meet you and check out your gear for sale.

I missed Puyallup last year for the 1st time in 20 years. Had to attend my mother-in-law's funeral that day,but that won't happen again :roll:

147.54 likely would be a terrible place to do P25, unless you like on-frequency NBFM traffic... Probably ought to go to an area of the band where that sort of thing would be better tolerated, say, 145.55 Mhz or so...

I will also be at a boot most of the day look for snoqualmie and solar stuff all in a row.

We have been using 7.54 P25 for years now.


Jim

Yup. In use all across the US and Canada. I know there is a few analog users of 7.54 down my way I ran into and just didn't know about P25 but once I gave them the story they had no problem.

For analog, I suggest using the Hamsexy/Batlabs frequency list:

146.495 w/67.0 PL BW1
446.495 w/67.0 PL BW2

We will also be on 446.025 P25. I wish this cheap radio I have would do MODAT!!

For those without P25 I will be on 147.540 no tone at the Icom booth at 11am.

146...Huh? Maybe in "Batlabland" but Puyallup is in Western Washington the last time I checked...

If one looks at an "ARRL" bandplan (which, by the way, is NOT standard nationwide) certain frequencies within the 2 meter ham band are INTERNATIONALLY set aside for Satellite uplinks and downlinks... CW and SSB subbands, EME, beacons, etc.....

The rest is "hacked up" for repeater outputs, inputs, packet, and FM simplex. And even some space for "Experimental, mixed-mode" stuff...
:mrgreen: from 145.510 Mhz through 145.79 Mhz... :mrgreen:

This is where it gets "weird" as how this is done differs from one region of the country to another...

Conventional simplex frequencies up here are "stepped" according to what the repeaters are doing! This assures maximum utilization of the available bandwidth between repeater output/input pairs and minimize interference to repeater stations when operating near those limits. As the repeater coordination gang decided more than 30 years ago to place FM analog (15KF3) repeaters on 20Khz steps in Western Washington, followed by Oregon and Eastern Washington... Up here we live in a "20khz step" FM simplex world...

Its amazing how many folks go through their ham classes and never receive this critical information... or for that matter, Extras who have been hams forever :bowrofl:

Moreover that Brad guy who moderates this forum also utilizes 147.540 Mhz... NBFM...Simplex...

Also one must bear in mind that the Puyallup hamfest is one of, if not THE most attended gathering of Ham radio operators in the Pacific Northwest... and nearly all of them have some sort of portable radio so they can yak with their friends while browsing the "junque"... thus creating one of the most "RF crowded" environments known to man, with the exception of possibly some of the busier communications sites... or 75 phone during an HF contest...

If you don't believe me, just bring along a spectrum analyzer and have a look... With all the "junque" containing non-linear junctions of some sort,
and all those folks with portable equipment transmitting simultaneously,
the intermod can get ferocious! Especially on 2 meters, as that is what 90% of the hams packing portables will be using...

On 440, intermod is less of an issue... but the lack of bandwidth allocated to simplex use means "co-channel" interference WILL exist!
Even with your favorite DCS code stuck in the box...

I have not personally surveyed the FRS channels to see what they are like during this event in the past, but I imagine they may get at least as busy as they do on a "good snow day" at the ski resorts...

Heck.. I have even seen folks using NEXTELs... :puke:

I might even be there...

what? I might have missed something here... I assume your reply or rant? was directed at KE7JFF? I could be wrong here. but this didnt seem like a nice way to tell someone your opinion.

and to correct some points... You said that ARRL isnt followed "everywhere" well it should be since ARRL is the manager for spectrum for FCC in the USA ..so hence the confusion on your post since the ARRL plan is followed by every major VEC that I am aware of obviously still technically a volunteer basis which still further confuses the post apparent harshness to someone not following "rules" my only guess is the stab at the 20khz "channelized" for intermod prevention. again no rules there but this aint CB and we don't use channels. :lol:

Second.. I dont see any frequency on this page that is out of the band plan....
http://www.arrl.org/FandES/field/regula ... an.html#2m
seems that everyone is using simplex and within 5khz buffer for edge of the "plan"

T3B01 (A)

What is a band plan?

A. A voluntary guideline, beyond the divisions established by the
FCC for using different operating modes within an amateur band

T3B02 (C)

Which of the following statements is true of band plans?

C. They are voluntary guidelines for efficient use of the radio
spectrum

T3B03 (C)

Who developed the band plans used by amateur radio operators?

C. The amateur community

G2B03 (C)
What should you do if you notice increasing interference from other activity on a
frequency you are using?

C. Move your contact to another frequency
