1. SEPTEMBER 2014 SCOPE THE PALOMAR AMATEUR RADIO CLUB NEWSLETTER Good News From PARS I am writing to share some absolutely INCREDIBLE news with you Last night August 5th 2014 the Poway City Council approved an amateur radio ordinance that allows a ham to erect up to a 65 ft high amateur radio antenna with just a building permit This is an incredible victory for amateur radio For many of you who have followed this saga for a City that has never allowed anyone even the Federal Government to erect anything over 35 ft this is amazing Poway hams began the quest for this solution since 1999 Over the past three years and recently with the assistance of the ARRL and an exceptionally gifted attorney Poway hams prevailed THANK YOU THANK YOU THANK YOU Here in Poway we are extremely grateful for the support we received from hams throughout San Diego County Their attendance at the Council meetings gave clear indication to the Council members that this matter needed to be taken seriously We Poway hams thank you for taking the time even on a nice summer evening to attend what had to be one of the longest meetings in history I must remind myself that we saw Democracy in action It is like making sausage but in the end we got great bratwurst Again thanks for your support 73 de NN3V Charlie Come to the Faire November 2nd 2014 PARC will participate in the Carlsbad Street Faire Save the date and2. it s a two level squelch on off indicator The battery level indicator has three levels but it seem to respond linearly to battery life left Channels can be displayed as a frequency or a 7 character alpha numeric name The radio had both A and B sides The display mode for each side can only be frequency or alpha numeric for the entire side and cannot be intermingled I found this to be a major functional annoyance The radio supports both VFO and memory modes like typical ham radios but since it does not have second knob all frequency memory tuning is done via the keyboard I did not find that very pleasing since pushing the Up Down buttons is much slower and less comfortable than a rotary knob Configuring typical operating modes such as repeater shift tone and tone squelch is all done via the built in menu system Getting in and out of the menu takes a minimum of 5 key strokes To rapidly switch modes this can get quite tedious Programming memory channels is the most counter intuitive procedure and mastering it will take a number of failed attempts The most practical approach to programing memory SCOPE page 6 channels is to use the USB cable I tried the Boafeng software unsuccessfully but did have good luck with CHIRP The scan rate in either VFO or memory modes is done at a rate of roughly two steps per second Compared to typical radios this is obscenely Slow For all intents and purposes the sca
