Pardon my butting in, Jeff... what is the Lynx? I'm guesing that it's a large network. Some details? And why would they charge such an exhoribant (sp) fee to join and mantain a membership?? _Ray_ --- Squish v1.11 * Origin: Deep Space 417 - Exploring The Final Frontier...

I picked up one of these via an Internet dealing. A fairly nice radio, actually. It's a 2-meter "all-mode", narrow and wide FM, and both upper and lower SideBand, as well as CW. Just as a note, I'm glad that it's not exactly what was listed in the manual. :-) It called for this to be able to transmit only 144-146, while receiving 144-148. Well, this can xmit and receive 144-149. :-) What I'm wondering about, also according to the manual, the listed sensitivity for this old dog is "more than S/N 30 dB at 1 uV input (50mW)" on FM. It lists 10 dB at 0.3 uV on SSB. Outside of getting an amp with preamp, which I'm thinking of anyway since it's only 10 watts out on either FM or PEP, is there any way of tweaking the sensitivity a bit more? I've had a few QSOs where they could hear me just fine, but I couldn't hear them very well. (I know, improve the antenna first, but had to ask this, too. :-) _Ray_ KB0STN --- Squish v1.11 * Origin: Deep Space 417 - Exploring The Final Frontier...

How many are willing to climb a tower to do otherwise? I build VHF/UHF yagi's for a commercial customer. Fortunatly, I can tune them while on or 1/2 wave above the ground. If I tune an antenna with the swr bridge at the antenna and then place the swr bridge at the other end of the coax, there's a difference. 1.2:1 at the antenna, 1.9:1 at the tx. No amplifier, No antenna tuner, no etc.. Now what do I tune to get 1.5:1 or less at the tx? RW>> ... It's not bass unless you can feel it! JE> JE> Bass is meant to be felt, not heard!

No problem. I'm not much into Resistor type antennas although I have designed a 23cm one using rhombics. I feel the resistor robs the antenna of power. EX: Anyone can get out on all HF bands with this simple antenna: It's a Cantenna or Dummy load to match the power output and a random wire. It's a perfect match for every frequency the transceiver can produce and you can still get out fine. Of course the power to the random wire is just a small percentage of the power delivered. Basically it's a 'work all bands at 1.5:1 or less' antenna. Is it good? For the radio it is. Fort getting out and making contacts ... well ... not really. -WS --- XRS! 4.50+ * Origin: KB4YLY, Moderator (1:374/73.2) --------------- FIDO MESSAGE AREA==> TOPIC: 188 HAM TECH Ref: E4C00007 Date: 04/07/97 From: WAYNE SAROSI Time: 08:19pm \/To: ALL (Read 4 times) Subj: Field day -5 Field day antennas and kits : part 5 Rotor use on field day: Somehow, rotors have been deemed off-limits in some unsaid word by amateurs during field day operations. This is nothing more than pure BS. If you have a beam antenna then get that rotor under the beam and use it, especially if you are running 'A' for field day. If you believe an amp or two draw on a generator for 30 secs is going to ruin your power source, well ... what can I say. Even in an emergency condition, it is not necessary to run a wire antenna and have a car battery as a source of power every time. But that may be all you have. Rotors work and they work well. Pre-preps include quick disconnects on control cables, lubrication of the bearings, U-bolt de-corrosion and lubrication, pre-testing as a MUST before using a rotor on field day or in emergency use. Rotors can be stored in storage boxes made of wood or old luggage. SOME NOTES: o Do not over rate your rotor. - Light duty means light duty. Don't stack a 10m and 20m beam on a rotor built for a TV antenna. o Do tin the wires before attaching them to rotor and/or controller. - Frayed wires are shorts waiting to happen. o Do not attach the control wires with the control box powered. o Do disconnect via the QD connector when lightning storms are in the area. (MOLEX) - Power down the rotor and use the QD. It's the one item we seem to forget in a lightning storm. -WS --- XRS! 4.50+ * Origin: KB4YLY, Moderator (1:374/73.2) --------------- FIDO MESSAGE AREA==> TOPIC: 188 HAM TECH Ref: E4C00008 Date: 04/07/97 From: WAYNE SAROSI Time: 08:21pm \/To: ALL (Read 4 times) Subj: STATS at my BBS Just to let you all know : HAM_TECH BEAT HAM FOR THE FIRST TIME IN HAM_TECH ECHO HISTORY on The Bear's Cave BBS 374/73 in weekly stats, 1.3% to 1.0% I'm happy! :-) Thanks! -WS --- XRS! 4.50+ * Origin: KB4YLY, Moderator (1:374/73.2) --------------- FIDO MESSAGE AREA==> TOPIC: 188 HAM TECH Ref: E4C00009 Date: 04/06/97 From: HARVEY HARBICHT Time: 09:12pm \/To: WAYNE SAROSI (Read 4 times) Subj: Field Day -3a >Field Day Antennas & Kits - part 3 Parts 1 and 2 never showed up here.
