I am very happy with the "features" on either radio. On the other hand, the biggest problem I find in our area (Denver, CO) is that the TH-28A seems to have way too wide a front end in the high intermod areas. When I get downtown with my TH-27A, I fight intermod, the TH-28A and my wifes TH-78A (dual band) get almost intolerable. This will be a problem with almost any hand held. The new Kenwood models are supposed to be better on power than the TH-28A but I have not had to chance to try one. 73 -- Joel KG0IL ------------------------------ Date: Sun, 20 Mar 94 20:19:17 PST From: ihnp4.ucsd.edu!pacbell.com!sgiblab!swrinde!emory!europa.eng.gtefsd.com!library.ucla.edu!news.mic.ucla.edu!unixg.ubc.ca!nntp.cs.ubc.ca!mala.bc.ca!oneb!ham!emd@network.ucsd.edu Subject: HTX-202 To: ham-equip@ucsd.edu I'm considering the purchase of the Radio Shack handheld as a spare handheld, especially since they're on sale 'til the end of the month for $259 Can. Can anyone tell me if other, larger batteries will also fit on the RS radio? It doesn't look like much capacity to me... Thanks, Bob. Robert Smits There is *no* idiotproof filter.

In the manual for the 440S, it lists the AT-250 as optional equipment. I got the manual for the AT-250, but it does not address how to interface it to the 440S. Anyone know how??? Please help! the AT-250 works (tried it out on a 430.) Thanks!

That should be about 1500.00 There is just no radio that stacks up to it at that exact price range. And has anyone but me had problems with those noisy-high distortion Audio output amps in the ICOM xcvrs? My hearing is real good in the upper freqs..(ie 16K) and the odd harmonic distortion in that range gives me real bad listiner fatigue in short order. The IC-751a series is real bad about it.. 73 Bob AA5PB ------------------------------ Date: 21 Mar 1994 22:02:02 -0500 From: ihnp4.ucsd.edu!dog.ee.lbl.gov!agate!library.ucla.edu!europa.eng.gtefsd.com!howland.reston.ans.net!news.ans.net!hp81.prod.aol.net!search01.news.aol.com!not-for-mail@network.ucsd.edu Subject: Strange Amplifier Interaction To: ham-equip@ucsd.edu I wonder how well the vertical is grounded. Even better yet, is it roof mounted? Since the TL922 uses a standard PI output network (the tune and load caps are in shunt), it could be that the grounding path is --> along outside of coax, to amp, thru tune/load cap, then to chassis ground and finally earth. The frequency selective effect would kinda hint that the transmission line is a part of the return circuit. If the vertical is BONDED to earth....then ignore me completely, I don't know what I'm talking about ;-) scott nx7u@aol.com ------------------------------ Date: Tue, 22 Mar 1994 02:02:22 GMT From: ihnp4.ucsd.edu!dog.ee.lbl.gov!agate!howland.reston.ans.net!math.ohio-state.edu!magnus.acs.ohio-state.edu!csn!col.hp.com!srgenprp!news.dtc.hp.com!hplextra!rigel!pooley@network.ucsd.edu Subject: Yaesu FT840 To: ham-equip@ucsd.edu Does anyone have any opinions/experience with this radio?

There've been several postings over the last months asking for comparisons between these rigs. I've also narrowed my choices down to these two if (when?) I ever replace my Drake rigs. One thing that almost never seems to get mentioned however... How do these rigs sound on the air! At the risk of starting a flame war, I'll venture the opinion that, in general, I find Kenwoods putting out among the best sounding signals on the air. I've got to admit that I enjoy hearing the reports of superior audio quality that my Drakes seem to get on sideband, and I'd hate to give that up. I like putting out a good pleasing signal! If it weren't for that factor, I'd probably lean towards the Yaesu. As it is, I'm not sure. Any thoughts or comments on the transmitting audio qualities of the major brands on sideband, particularly these two radios?
