Glenn, I have the names of some vendors i've looked into, you might like to yourself, and readup on the info: GLB GREGORY ELECTRONICS 1952 Clinton st. 249 rt 46 Buffalo NY 14206 Saddle Brook nj (716-824-7936) (201-489-9000) (kits,boards,everything) (good used commercial stuff) Micro Control Specialties Hamtronics (div kendecom) 65 moul rd 23 ELM pkwy Hilton ny 14468-9535 ? Groveland ma 01834 (716-392-9430) (617-372-3442) (boards,kits) (rpt's,boards,new) Advanced Computer Cntls Yaesu Cupertino ca. Paramount ca. (408-749-8830) (213-633-4007) (controller stuff) (complete rpt, or less cntl's) Spectrum (215-631-1770) (boards, cmplt rptr's) I suggest you call them , get All the info then decide, I am the Technical person on a machine w/ abt 150 members, and only qualify to answer about spectrum.(censored)Actually i think there receiver, and xmtr boards are ok, but OVERPRICED, as far as their power supplys, well i'd be happy to get more than a year before they checkout. not the best designed i've seen, my schematics are filled with changes They've made. Their autopatch boards are "old as dirt" logic, have to retune 567's when room heats in summer. I've said enough , you get the point. I've just researched what your about to and i think i'm going to go with micro control, they were the only ones that sent me a schematic without asking for one, also asked me if i'd like names and numbers of others in my area using them, to ask what they thought of the stuff. I'm impressed with the receiver spec's, reads as the best on the market, i'm skeptical of most but this one looks GOOD, and I cant afford less than the best receiver. The transmitter seems well engineered also, their machines are the only ones that i know of that have a deviation, meter as well as basic's. and their simple machine is abt 1200. not bad considering what spectrum wants for NOTHING. quiet tmos transmitter transistors, and 7 helical resonators in the receiver seem like an ok basis to build on. Yaesu has a nice no meter simple machine for about 899 (w/o dtmf,ider etc, as you want) but the receiver scares me, the specs look poor, ie: ".5 or better" ?? i cant take a chance on the better. hi hi and the selectivity was about -6db at 15khz i think(maybe 12) but the kendecom receiver was abt -105! not bad, for same khz.(im talkin two meters now but if they cant do well on 2, can 440 be better?) Well good luck, im going to drive up to the boston area in about a Month to pick it up(i've ordered one), and i'll let you know what the shop looks like up there, if you like. I've been to spectrum MANY times and i'm not impressed, a few years ago they were ok, but since i think all have left, and the new folks dont impress me on the phone. I Grilled the guy at kendecom and he still had the answers i wanted. Next duplexers, never heard of tx/rx systems but, i know celwave/ phelps-dodge are harder to tune, and need 6 cavities, compared to wacom, I have 641 wacoms, just added 150w final and their still holdin their own. hi hi Wacom only uses 4 cavities, and has pass band tuning on top and reject freq. rods on side. EASY! to tune... And if you have any problem Kit Parsons WILL spend the time on the phone you need, EXELLENT customer service, nice club discounts. They get my vote. One more thing, the icom repeater, well it looks good in the pix but try buying it without THEIR controller, and why waste the money when you want yours in there? also after reading the net lately, think i'll skip icom for a while. Too many back 4-6 times till fixed stories. hihi Good luck and if you remember, let me know how you make out. ....es best 73's ...de ka2qhd ...johnd Greatly appreciate comments on kendecom as theres still time to cancel.
